The renowned German vehicle manufacturer Liebherr has introduced a brilliant grab for the mobile harbor cranes. This smart grab has been named as Smart-Grip that is said to have the ability for boosting productivity over twenty five percent. The company has launched a game changing technology that functions as a smart system that has the ability of optimizing the rate of grab filling in an automatic smart way. The smart-grip offers a variety of benefits such as zero overloads and exceptional performance.
The new technology introduced by Liebherr functions intelligently for increasing the filling rate and helps in avoiding overloads and saves on hardware. Conventionally, just seventy percent of the capacity of the grab is utilized because of sup-optimal angles of the grab and a material density that varies frequently. Attempting to get the 2 in the right way must be a tough challenge for the operators and demands a collection of various grabs to serve to different kinds of materials. Because of extensive and keen analysis, the company strived hard for bringing up the perfect model of grab-fill for a variety of material densities for optimizing the filling rates. The latest high tech system also includes an automatic component that adjusts the behavior automatically to suit the compression, bulk density, and granularity and other related criteria.
When the grab moves through the first few cycles of load, the filling is optimized automatically from seventy percent to the maximum capability available keeping in view the size of the grab, the load of the crane along with out-reach. The company states that the intelligent system can achieve the maximum rate of the grab filling in the initial 7 cycles. This system also works for preventing the overload which can result at the time of pulling load at the grab of a sticky kind of material. This leads to the overload of the crane and leads to shutdown of the pending work unless the system is reset. The mentioned special feature improves productivity on one hand and extends the longevity of the crane on the other hand by attempting to avoid the stress resulted by the sudden overload shutdowns and saves time and fuel.
The smart-grip avoids overloading automatically and besides this the crane has the feature of manual operating and can be operated for different kinds of loads in a manual way. If an operator of the crane wants to load forty ton truck for instance, he can manually set the system to fill the grab up with forty ton. Isn’t it amazing? The intelligent system might also be utilized for cranes manufactured by Liebherr in old times. The installation of the system has been previewed to be simple, easy, and quick.
Smart-grip is the ideal solution for optimizing grab filling rates. Liebherr has collected in-depth data and has done keen analysis and because of this the company has managed to deduce the ideal grab fill model via data mining. The system adjusts automatically and recognizes the bulk density and compression itself. It recognized the current frame conditions as well including the impression depth and kind of grab. The system makes sure that the grab fill rate is above seventy percent. Within 7 cycles, the grab’s total capacity is utilized.
The Dijon based Joly location has received the first Ruthmann T720 truck in France. This would be the first Ruthmann truck to be delivered in the country. The latest machine was taken for job in the Dijon’s historical central district where it was set to work on a 5 star hotel situated next to the Grand hotel de la Cloche in the city center. The building was established between year 1881 and 1884 and was protected from demolition in the 1970s when an order for preservation was placed on the walls and façade.
The new lift was simple and easy to work on the whole of the façade and the roof from one single position. The lift’s long telescopic job let to reach to the hotel at the back of the building where it performed repair and maintenance over the roof slates and gutters. The lift had the ability to work on the front and back of the hotel. After the work was done, the lift was moved towards Paris and was set to work on Brest.
This amazing machine has been mounted on an 8 into 4 by 4, has one axle on the front and 3 axles at the rear. Axle one and axle 3 are the steering axles and axle 2 and axle 3 are the driving axles. The wheelbase is a bit short that 4.5 meter instead of 5.1 meter. Because of such measurements, the turning radius is way better as compared to any similar combination. Moreover, in rough terrain, the driving axles provide the driving power right at the point where the load is for exceptional traction. The front over hang is less than two meters.
The T720 is the latest addition to Ruthmann’s height series offering flexible access in odd situation. All credit goes to its extended telescoping with moveable jib. The model has a working height of seventy two meters and has a maximum lateral reach of thirty eight meters. The design shows that the operator would have 21.4 meter reach at a working height of sixty eight meters along with a hundred kilogram cage load. The Ruthmann T720’s flexibility lets the work to be done behind awkward obstructions including pipes, building fronts, and wires and cables. With the help of this model work can also be done at depths measuring up to twenty meters below the surface. All thanks goes to the jib system and the telescoping and rotating of the cage.
The T720 is designed to offer customers the advantages of extended length. The operators now get additional 5.5 meter of upper boom length as compared to other models in the series. A new feature incorporated in the model is that 4 outriggers can be manipulated individually from the back on both sides of the vehicles. This feature is added for providing better decision making while jacking and increasing safety on the site. The simple and easy positioning of the outrigger pads also results in decreased set-up time. The Ruthmann T720 has compact and precise dimensions with a total length of only 13.7 meters.
Nowadays, cranes have become the inevitable part of construction and transportation of heavy machinery from one part to another. Due to the excessive use of cranes in modern world, a lot of companies have emerged to provide top notch services for repairing, overhauling, fabricating, rebuilding, hydraulic repairing and painting crane. Cranes are basically the major element of different construction operations. These are also associated with great fraction of workers’ death on site. It is estimated that cranes are utilized for more than one third of all types of constructions and maintenance work.
The professionals related to health and security, are giving their services to construction industry. In order to provide crane safety, it is vital to supply devices, training and skills to insure that the latest techniques are properly used. Whenever cranes are used in specific area, it is essential to check all the precautionary measures are applied. The experts have complete knowledge of crane support equipment, engines, winches and crane assembly, so the companies hire support for on shore or off shore projects.
Causes of Crane Mishaps:
OSHA has checked out the ratio of crane accidents and searched out the four basis factors which are involved in crane mishaps. These are
Power lines contact
Unluckily, crane workers and crew members can be electrocuted in case of working close to overhead power lines. In order to avoid electrocutions, NIOSH or national Institute for Occupational Safety & Health has observed the facts behind injuries. It is noticed that workers, supervisors and employers are not aware of overhead power line operations of cranes. As a result, they do not use safety procedures. In order to provide safety against the horrible injuries related to electrical shock, CSA has given recommendation for safety. The proposals are as follows:
It is compulsory that crane operator should not come out of his cab. While performing his job, he is bound to be inside cab
It is visible that the ground in the region of machine can be energized due to crane operation. It must be the rule that employees remain away from the load area, ropes and crane
It is the responsibility of crane operator to keep the crane away from contact through shifting it in opposite direction to avoid mishaps
In case, it is difficult to reverse the crane from contact, the operator should not get out of the cab until and unless the lines are de-energized
Requisites for Reducing Crane Mishap Ratio:
There are five requisites which are important to follow to prevent damages. These prerequisites are as follows:
Regular Maintenance of machines
Provide training to workers
Use latest tools
Supervise the workers
Last but not least, a rental company must be hired which has latest cranes and ability to understand the right crane for your task. It is reasonable to choose a company that gives surety of personnel safety and crane maintenance. It does not only provide a secure place for employees but also boost up company’s standard.
A crane is basically equipped with pulleys and cables to lift the material. Generally these cranes are used in well known construction industry. The construction cranes are either mounted or fixed. These cranes can be controlled by an operator, through push button or radio type control. Whatever is the mode of crane operation, it is the responsibility of the user to provide protection to crew.
Basic Cranes for Construction:
Wheel Mounted Cranes
Commercial Truck Mounted crane
Luffing tower Cranes
Tower Crane:Construction tower crane
It is an advanced crane which is particularly used for lofty buildings. Tower crane are appointed to lift up the materials such as concrete slabs, generator, steel structures, cement mixing machine etc. Mostly, tower cranes are positioned on the top most places to transfer raw material easily. Basically these machines are fixed to transfer material and to lift or drop heavy equipments.
Tower crane have 6 basic parts which are known as the base, the hook, slewing unit, weights, jib and operators cab. Tower crane can be arrived at site area through tractor trailer. First of all the crane is assembled. Jib and machinery are assembled later on. The next step is to add counterweight. In order to get the highest position, the crane keeps on growing one section at a time.
Selection of Appropriate Tower Crane
It is not a difficult process to choose the most authentic tower crane to carry out the function. It is noticed that almost 90% mishaps are caused due to use of wrong tower crane. The efficiency of a tower crane is reduced when it is used for inappropriate task. While selecting a crane, check the center of gravity to the maximum access of tower cranes.
Source of Great Productivity
These cranes can save cost as well as time. The procedure is easy; the work level is accurate and fast. Latest cranes have overcome the drawbacks concerning pollution and noise which are usually generated due to other cranes. These cranes provide more safety features and are best for site areas. There are different ways to perk up the productivity and efficiency through using construction crane. For example;
Crews that depend on manual labor for the execution of their job can get benefits by using tower cranes. As a result productivity is improved as well as the stamina of workers.
A more dedicated work is performed by using cranes. It can easily navigate the equipment and does not disturb the workers as well.
It is not necessary that the crane operator should be well experienced and proficient person, as the work can be performed with the help of remote control. It reduces the need of the workers. Cranes are multifunctional and a variety of functions are carried out by one crane. Otherwise multiple workers are required for lifting, transporting and dropping the material but the crane has decreased the use of workers.
Material can be easily transported to the receiving location and then transfer to location of need at the right time.
Cranes have three fundamental types which are Monorail crane, Jib crane and Overhead Gantry crane. The cranes have different designs which are particular for executing incomparable tasks at cost-effective rates. Here are some of valuable kinds of crane:
Kinds of Crane:
It is a single rail crane. It is used to transfer the material from one area to another. It has the capability to cover great distance in a short length of time. It can be attached with a roof structure or can be mounted through its own support or crane. It is helpful in transferring objects in a straight path. If the material is required to move from one part of site area to another, monorail is perfect to use.
It is a kind of crane where jib or horizontal member is preset and gives support to portable hoist. It has a limited platform and has traditional structure. Now, the improved versions are used such as Articulated Jibs and Cathead Jibs. Cathead jibs can change retractable type of arms which are ideal to move in a fixed obstacle like building column. To provide extra movement, the jib can move to and fro by an arch. It has free to stand structure which has made it mobile crane. Jib crane is specially used for fix work when items are required to move from one spot to next. Mostly it is used for packing material, lifting a product, moving an item out of the machine or from a work bench.
Jib cranes can mount equipments like hydraulic line tools and air tools. Jib cranes are suitable for small work site. If it is important to cover more distance, Gantry cranes or Monorail cranes are the right choice.
It is a steel based crane and perfect for the movement of heavy load horizontally. It can bear 350 tons of weight.
Overhead or suspended crane is different to Gantry crane as the trolley/hoist moves only. It is typically mounted along lofty columns.
It holds hoist in unchanging machinery that moves horizontally beside the rails, often fitted on mono girder or twin girder. The frame of crane is sustained on gantry system along with wheels and equalized beam that move on gantry rail, mostly vertical to the travel track of trolley.
Tower crane can be assembled to telescopic jib. The self erecting cranes are also included in tower cranes. These are capable to lift using jacks and best for telescopic use. No extra help is required for assembling these cranes.
Crane is available in different types and each is tailored to perform specific function. Sometimes the small cranes are used within a workshop whereas the tallest cranes are used for construction. In order to make the work feasible, special construction cranes are used. The cranes are usually fixed in the ground to avoid imbalance. The cranes are stable in nature and have protective measures to save the workers. The cranes are useful to save the time and help workers in performing the hectic tasks.
Gantry Crane is one of the most venerable inventions of modern era. It is designed to lift the profound substances and equipment which are impossible to lift by the layman. The cranes are accountable to transfer objects from one station to another with smoothness. It takes account of moving the goods up to towering height. It is excessively used in construction industry and production unit.
There are different sizes available in the market. The size and type are related to the functions performed by these Gantry cranes. There are many cranes particular for lifting objects and movement of material during the formation of buildings or bridges. Some of well-known types are Overhead crane, Overhead Bridge crane and Bridge crane. These three types have gained worldwide acknowledgement due to reliable assistance in work. Construction companies choose these types to get a lot of benefits. Some noteworthy advantages are mentioned here:
Easy to Transfer:
As compared to other cranes, Gantry cranes have a proper system for transportation. The goods and heavy entities can be moved from one place to another.
Easy on the Pocket:
The construction work is carried out within a certain budget amount. Gantry cranes always have a preference because of low investment and more benefits.
Capability to Lift Heavy Materials:
All cranes are manufactured with a limited range of weight. It is illegal and dangerous to put more weight than the capacity. Gantry cranes are powerfully built and able to hold weight up to 5 tons.
Lift Material for the Construction of Buildings:
When building or bridges or constructed, it becomes necessary to deliver the required material up to a great height. The crane can be adjusted to any height according to work structure and demand.
It is used in Gantry cranes for the effortless movement. The polyurethane is attached with rolling wheels for resilient and unproblematic movement.
As the Gantry crane has great demand all over the world therefore it can be searched out online. Moreover, the manufacturing department and factories select the rust resistant, hard-wearing crane for on-going projects.
Light in Weight:
It is good the Gantry cranes have manufactured with light material which helps in moving the machine. Side by side, the safety terms are admirable and protect the workers from injuries.
Easy to Sale:
It is simple to buy or sell the Gantry crane as the vendors and purchasers are available online.
The Gantry cranes have a long series of benefits. The cost-effective machinery has tension-free assemble and disassemble procedure. The adaptable design for working in a challenging atmosphere makes it the first-rated crane for construction use. Gantry crane is superior to the contemporary Overhead and Bridge crane. With the passage of time, the need to use these cranes is getting increased, that is why the excellent products are offered at different platforms. It is liable to work on safety basis. In case of nonstop lifting of heavy weights, it is suggested to arrange Gantry crane for permanent basis.
Cranes are used for construction purpose. The high rise tower cranes have attracted the people and are migrated to Dubai for sky-scrapers. It is a kind of feat of construction engineering. Tower cranes are eighty meters long and can perform overwhelming tasks without problems. The “moment” is the basic engineering principal that supports the towercranes from slanting over. If the weight is attached to the jib arm of crane torque or rotational power is exerted. The direction and amount of power “clock wise or anti-clock wise” is known as moment. Contrary to this, if the weight is attached to the mast, the amount of moment is less as compared to weight on jib. When the crane gets its highest position, it can easily tether to constructive area and use to build the highest buildings.
How to Assemble the Crane
One of the astonishing and extraordinary achievements of tower cranes is literally constructive structure. The assistance from a mobile crane, the workers get a protected position and put together the top most unit or tower crane-jib, machinery on and slewing unit. Before attaching the top most section, a hydraulic unit for mountaineering is used around the bottom of the crane (Operator cap and horizontal jib) to slide in the next section. As long as the new segment is secured, the workers use the hydraulic unit to climb up. The crane is built section by section itself with a slow or secured procedure.
Components of Crane
Hook and trolley are linked by cables to the motor of trolley which is positioned on the top most Jib arm. The operator is able to roll back the trolley by hand control.
The horizontal arm of tower crane is capable to maximize 85 meters outward. There are 3 sides of the arm.
The tower has 2.8 meter long sides. The four sides have diagonal, horizontal and vertical trusses to provide structural unity.
The power to lower and raise the load is offered by a winch. It is positioned with the machinery arm or counterweight Jib.
Hydraulic climbing section
The outside unit is affixed through hydraulic unit. The top section is lifted by a hydraulic arm to include latest sections below.
The tower cranes achieved stability by burying the tower in concrete which is weighted 185 tons.
It permits the Jib arm to move around 360 degrees to drop and lift the material around the construction area.
There are different concrete slabs which have tons of weight and are attached with counterweight jib to over-compensate the holding capacity.
Towercranes can be given on rent or lease for completion of projects. The safety precautions are provided to avoid damage or collapse. In case of complex building, the tower remains in place and becomes a long lasting part of the new building. As a result, the builder finishes the construction project and does not remove the tower from the completed project.
Explorer 5600 is the name of the new addition in the Terex’s Explorer family of all terrain cranes. The AT five axle, 180 ton machine was designed primarily for road ability. #.9 ft is the only extension space of the boom over the front and a boom off optional solution or the dolly option facilitates the model in meeting up the stringent standards of the road. The automatic rigging counterweight system permits the crane t get ready instantly for work.
The length of the carrier of Explorer 5600 is 41 ft which allows it to move and navigate easily through the urban and congested construction areas. Further on capability of tight cornering and cram steering are also offered by the all axle steering.

With a maximum system length of 312 ft, main boom reaching 223 ft and load moment of maximum 480 mt makes the Explorer 5600 stand out among the strongest present lift charts in the whole capacity class of this working range. Explorer 5600 offers 38.5 tons of lifting capacity during telescoping and a hoist of 22,076 lb. ft, along with a rope of 21 mm and a cable pull of 10.9 ton that entails reduced reeving for enhanced performance and shorter times of rigging.
The explorer 5600 comes with a power management system that offers best efficiency and performance for every load cycle to provide whenever required power and economy of fuel when the upper structure of the crane is operated. Not only does this reduce the maintenance of the components with service requirements but the positioning of the gearbox and engine are also done in a centralized area in order to reduce service time.
A new enhanced electrical braking performance system is given to Explorer 5600 that offers reduced brake pad wear, while the driver’s upward hill drive is supported by the dynamic launch control.
Terex crane equipments are known for safety being their paramount feature and same is the case with the Explorer 5600. Access to cabs on the upper structure along with reaching upper components is made easier than ever before with multiple egress and access points. The 26.7 ft X 24.6 ft outrigger base offers stable and smooth operations during load lifting. The package of working lights provided with the Explorer 5600 offers exceptional visibility of the site at night owing to the xenon working lights package which is optional along with other optional features including the pendulum load camera, the right hand and hoist cameras and tail swing cameras.
Terex’s Explorer 5600 comes equipped with IC-1 control system, which is a proven intuitive and efficient touch screen system as standard. All radius and loads input can be used by the IC-1 software system to configure and load charts as required enabling the operator to instantly meet the settings and requirements of a job site. Also the touch controller displays information about ten different working variables such as tire pressure, suspension system, axle load, status of brake system, etc.
The MK1033 is the latest and updated version of mini cranes revealed by Maeda in the ConExpo show. The mini crane comes fitted with an articulating boom. According to Maeda USA, Houston Texas’ president, Tony Inman, the MK1033 may be the only articulating knuckle boom mini crane available in the market today.
While the model has been introduced last year in the 2013 Bauma Show to Europe, however it reached the North American market this spring via the ConExpo Las Vegas, Nevada show where it was revealed. The production models are expected to hit the North American market sometime later this year according to the president of the Maeda, USA.
What makes MK 1033 stand out between other models of this genre, is its knuckle boom mini crane ability, which allows it to work in rather complex spaces, reaching out over objects combined with its maneuverability and compactness. This mini crane with articulating boom is said to be exceptionally useful for jobs such as glass installation, renovation or maintenance of factories, petrochemical factory working, housing construction work and several other types of tight quarter jobs.
The MK1033 is able to lift a maximum weight of 2,190 lbs at a radius of 3 ft 4 inches, whereas it can lift that load to up to 23 ft 11 inches of height. The maximum tip height of the MK1033 reaches 37 ft 5 inches and it can lift up a weight of 1,388 lbs to its maximum height. Given the horizontal placed articulating top section of the boom, the MK1033 can reach a height of 23 ft 11 inches, lifting 573 lbs at a radius of 15 ft 7 inches. With a horizontally laid out, straight boom, this crane model can travel a radius of 31 ft 8 inches lifting 400 lbs of weight.
With measurements of 2 ft 4 inches in width, 8 ft 11 inches in length and 6 ft 6 inches in height when stowed, fitting through a single standard doorway is no problem for the MK1033. This crane is able to fit into some real tight and complex spaces. With an excellent 7.3 psi of ground bearing pressure, MK1033 weighs only 4,410 lbs.
The crane comes with a standard 4 tier diesel engine with power options including LPG fueled, gasoline and 380 V and 230 V electric motor. The 4 outriggers individually can be positioned at any given 7 positions to find a perfect combination for any complex set up.
