Using a combination of hydrostatic and mechanical drives, the technologically advanced three-range transmission can offer up a fuel saving of up to 20% by delivering a stepless speed range from 0-40km/hr without clutches and without interrupting the drive.
Cleverly, the HVT R3 will allow the operator to preset a maximum travel speed, or preselect a fixed engine rpm and use the transmission’s characteristics to keep the engine working at its most fuel-efficient point.
Liebherr used INTERMAT 2012 to show its new 380 EC-B 16 Litronic flat-top crane. The 380tonne unit tops the 15-model range, which starts from 50tonnes. The new “flagship” can lift loads of up to 3,400kg at its 75m maximum radius. With the Litronic system, the 380 EC-B 16 can provide up to 20% more load lift at the push of a button. This is achieved by integrating the load-moment limiting system, the ABB operating-range limiting system and the MDA machine data evaluation program.
TowerLight is increasing its presence in the site security market with the launch of the Security Tower. Based on the firm’s four-head LED lighting tower, the machine is equipped with a wireless camera system that can provide secure video of the site in daylight and at night. The tower is currently available on a skid base, with fork pockets and crane hook, but will also be produced on a wheeled chassis.

Bonfiglioli Trasmital has developed a new series of travel drive gearboxes for use in large, heavy duty tracked machines. The firm is now offering three new product sizes, the 722C, 724C and 726C, which extend its range of tracked travel drives. The 722C develops a maximum torque of up to 330,000Nm, making it suitable for use on excavators of 120-150tonnes, as well as cranes and drilling rigs of 180-230tonnes. The 724C develops a maximum torque of up to 450,000Nm, and is specially designed for large cranes
