Meet Liebherr LTM 11200-9.1, the most powerful truck crane in the world today, the brainchild of a German company.
Its technical characteristics speak for themselves:
- maximum lifting capacity of 1200 tons;
- telescopic boom with a reach of up to 100 meters without extensions and up to 170 meters with extensions;
- a travel speed of up to 75 kilometers per hour;
- 8-cylinder chassis engine equipped with a 500 kW turbocharger.
All this is embodied in a unique self-propelled truck crane, which in 2007 was recognized as the best development in the field of heavy-duty and mobile truck cranes. Although Liebherr is preparing to launch a new, more advanced giant, the LTM 11200-9.1 series crane remains out of contention for now. Most cranes from a similar weight category are crawler cranes or lattice boom cranes. However, unlike the Liebherr LTM 11200-9.1, they can only be transported to the required destination in disassembled form. A powerful 9-axle chassis and 680 horsepower engine allows the powerful German truck crane to reach a speed of 75 km/h.
In this handsome German manufacturer has embodied all modern engineering developments and the best design solutions. The unique telescopic boom is capable of lifting a load weighing one hundred tons to a height of 80 meters. Extension of the boom sections is carried out in automatic mode, as well as their fixation in the required position.
Although the basic configuration of the truck crane implies lifting of loads up to 400 tons, additional equipment allows to achieve the figure of 1200 tons. The heavy-duty nine-axle chassis with 18x8x18 drive is equipped with R25 single tires. The chassis is equipped with active steering of the rear axles, which was developed by Liebherr especially for this series of truck cranes. The steering directly depends on the speed of the crane on the road, so when slowing down the rear axles are steered more actively, and with increasing speed - provides a stable and smooth movement of the machine. The crane is equipped with advanced disk brakes, the power of which surpasses any braking system. And it is not surprising: for such a giant as Liebherr LTM 11200-9.1 increased safety is important.
Speaking of the safety of work, it is impossible not to pay attention to the presence of a perfect system, which includes a test system, hydraulic valves, load limiter Liccon. All working functions of the truck crane are controlled from the crane driver's cabin and controlled by on-board computer. When moving such equipment on the highways must have a proper escort, otherwise the 108-ton machine can take ordinary drivers by surprise. 108 tons is the weight of the truck crane with chassis, supports, two winches and a turntable. The counterweight weighs 202 tons, as well as the boom,
