The new Liebherr LTM 1350-6.1 mobile crane due to its outstanding load capacity and boom length sets new standards in the 6-axle class. The mobile crane is equipped with a 70-meter telescopic boom, which is 10 meters more than the previous model of the Liebherr LTM 1300-6.1 crane.
Lifting characteristics of the crane are significantly improved, and thanks to the newest Y-shaped boom suspension system, the Liebherr LTM 1350 mobile crane boasts with some of the best performance among all compact six-axle models. The main boom of the truck crane can be attached to a lattice extension of 6 to 42 meters long so that the total length of the boom can reach 112 meters. With the leasing of a Liebherr truck crane that has a lifting capacity of 350 tons, the operator will be able to carry out the most complex lifting and assembly jobs that were previously inaccessible to cranes of similar lifting capacity. The transport weight of the Liebherr LTM 1350 truck crane is 72 tons. The total weight of the counterweight is 100 tons.
The details concerning technical aspects of the Liebherr LTM 1350-6.1 crane’s work:
- Max load-carrying capacity – 350 tons at an exit of 3 m.
- The boom is 14.9 m – 70 m (telescopic).
- The boom extension: 6 m – 42 m.
- The speed of the movement – 80 km/h (max).
- The weight in the transport position is 72 tons.
- The weight of the counterweights is 100 tons (total).
Use of cranes
An automobile crane with a carrying capacity of 1.2 to 3 tons with a boom of 3.5 to 8.5 meters is the most suitable for installation works of all truck cranes. It has great maneuverability and can be successfully used for repair of two-storeyed buildings of complex configuration and for installation works with complete replacement of all internal structures, supply of elements through the opening in the dismantled roof. To supply weights to window openings, winches are often used in combination with cantilevered beams that have blocks. Console beams are installed on the roof. Such cantilever-winch cocks are used for finishing works on the facades of buildings.
With the removal of the cargo area, this lifting device is used to feed the products into the window openings, with the weight of the delivered small-volume cargo is up to 200 kg. The subsequent movement of cargo inside the premises is carried out manually or with the help of roller-boats and other devices. Such work is very laborious and is carried out with the help of hand worm hoists with the carrying capacity of up to 1 ton. Columns and girders in this case are not reinforced but made of metal. Metal columns are lighter than reinforced concrete. They can be manufactured in individual sizes, based on local conditions.
Assembly-disassembly of the crane at the place of production can be included in the total working time.
