Liebherr has developed the LTM1750-9.1, a nine-axle all-terrain crane with a maximum lift capacity of 750 tonnes. The 52m telescopic boom machine is carried by the machine and offers a 154m maximum lift height, with a maximum working radius of 112m. A luffing fly jib can be added in 3.5m increments to take maximum lift height to 91m. Weighing in at 108 tonnes in transport configuration, the LTM puts down 12 tonnes per axle. However if the machine’s boom supports are removed the crane can travel at 11 tonnes

718 Liebherr has developed the LTM1750-9.1, a nine-axle all-terrain crane with a maximum lift capacity of 750 tonnes. The 52m telescopic boom machine is carried by the machine and offers a 154m maximum lift height, with a maximum working radius of 112m. A luffing fly jib can be added in 3.5m increments to take maximum lift height to 91m. Weighing in at 108 tonnes in transport configuration, the LTM puts down 12 tonnes per axle. However if the machine’s boom supports are removed the crane can travel at 11 tonnes per axle for those countries with reduced allowance. Alternatively the boom can be removed completely if necessary, to reduce the crane’s travel weight to less than 40 tonnes.
Liebherr has developed a hybrid drive system for its HS8300HD heavy duty cycle crawler crane. The 350 tonne machine generates electrical power from its hydraulic free-fall winches, which offer up to 50 tonnes of line pull. Under this Pactronic system surplus energy is stored in a hydraulic accumulator and regenerated to assist the engine, reducing fuel consumption. This reuse of energy also cuts emissions from the machine.
