It’s really a proud moment for the Liebherr-Werk Ehingen GmbH because they have successfully delivered 30,000 cranes to their customers. They touched glory by supplying LTM 1500-8.1. Delivery of Liebherr 500- tonner was made to Grupo DPH that is a Mexican company. In making the decision of purchasing from Liebherr the significant aspect for DPH was the presence of Liebherr Mexico S.de R.L whose foundation was laid in the year 2013.
The giving of LTM 1500-8.1 was carried out in southern part of Mexican region at Salina Cruz. Grupo DPH owns a repository at the port that presently works as center of distribution for wind power plant makers Vestas. Presently warehouse is equipped with one hundred and thirty generators for turbines of wind. Their shipping to wind farms in Mexico and other Latin American regions will be carried out. This is clearly indicating towards the point that first works were expecting newer LTM 1500-8.1 crane at the time of its arrival.
It bused between loading of generators at the center of distribution and a closely situated wind farm. Other works for this one have the inclusion of pre-assemblage task for platforms of oil. For past sixteen years 500-tonner has been in the market and delivery of four hundred and fifty units has been carried out.
According to Liebherr the foremost functional use for their LR 11000 1000 tons crane, has finished its initial lift at an oil refinery at Romania. LR 11000 was utilized by the Felbermayr for working upon a confined site that has a working area of 35 meter by 35 meter at Petrom refinery in the Plojesti close to Bucharest for lifting big cylinders of steel the largest of them had measurement of 58 meters in length, it weighs 335 tons and radius is 27.5 meter. Formation of the lattice boom and thirty six meter jib was to be accomplished in a narrower lane that’s only five meter wide.
It was mentioned by Liebherr that handling of load was full of excitement because the possibility of determining the proper weight of column was less.
For overcoming sliding upon higher bridge of pipe raising of column was reach 80 meter, reduction of radius was noticed and movement of crane to only few meters took place. Without reduction of radius of ballast pallet that were suspended by 2 m to 13.5 meters the clearing of pipes as well as pillars was not possible.
LR 11000 will go on working at refinery till ending of July. Felbermayr possesses a convoy of seventy cranes working at location that will be closing for generalized service.
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.
Liebherr unveiled at the ConExpo its 190 ton LTM 1160-5.2 five axle chassis mobile crane. The company has increased the load capacity to about 25%, of its new presentation compared to its predecessor, the LTM 1160-5.1. The newer version uses the same telescopic boom of 203 ft however has been reduced in width to 9’0” from its predecessor’s 9’10”. The reduced width now allows the mobile crane to move in constricted areas and drive on public roads as well.
What makes the LTM 1160-5.2 stand out of the crowd is its superstructure which is superbly powered by only a single engine unlike other cranes of the class which come with twin engine concepts. The crane chassis on a single engine operates using a mechanical shaft. This mobile crane is Liebherr’s second crane model of five axle to be featured with a single engine, while the initial one was presented at the 2013 Bauma as LTM 1300-6.2. In the crane chassis the gear shaft routes from distributor gear, using gears of 2 meters that comes all the way through to the center of the pump distributor gear’s slewing ring.
A six cylinder, Tier 4 final Liebherr engine stirs up 544 hp at a rpm of 1900 offering a 2,516 Nm torque at an rpm of 1350. The ZF-AS 12 speed Tronic gears are used to transfer power to the crane axles, while the zero wear hydrodynamic, intarder brakes perform as a retarder. The option of a current Telma Eddy brake is also available.
The low speed of the engine in the chassis offer adequate crane work power while the mechanical shaft allows a high level of efficiency. The removal of the superstructure separate engine offers a provision of condensed maintenance weight and work. The reduced weight helps load bearing components which in return enhances the load capacity of the crane.
The new add on program developed for the unique crane drive concept offers a single engine to cranes while the mechanical shaft option offers the possibility of running the machine on very low rates of fuel consumption. Not only does this allow the pump drive to be completely disconnected automatically whenever the engine is idle but also reconnects it through an intelligent controller whenever required within seconds only.
Like most of the other mobile LTM crane models, the 1160-5.2 also features pneumatic disc brakes. The 190 ton rear axle model acquires electro hydraulic active steering based on the speed of the vehicle. This feature not only enhances the vehicle’s maneuverability but also decreases tire wear. The 5 programs of steering can be very conveniently selected at a simple touch of a button.
With a maximum weight of 132,000 lbs and axle load of 26,200 lbs, the new LTM 1160-5.2 is ready to carry a three sheave hook block, its dual folding jib and storage box with a liberal payload.
The new mobile crane also comes with a Liebherr LICCON2 crane control which offers the provisions of a cost effective and simple extension towards an absolute remote control crane system.
