Bonfiglioli is launching heavy duty drives for large machines
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

ZF will focus on efficiency and reducing fuel consumption at this year’s show. The transmission and driveline component manufacturer will present its Ergopower efficiency package that combines the cPower continuously variable transmission with the ZF Hybrid module that should be commercially available in the future. cPower is a hydromechanical variable transmission that combines hydrostatic drive pumps with a mechanical powershift gearbox. Available for use in a range of machines, including wheeled loaders,
ZF has chosen a pair of radial hydraulic motors for use in its compact single-speed hydrostatic transmission, the 2HC85, which has been developed for compact wheeled loaders up to 100kW and 10.5tonnes operating weight. For high-torque start-up, the transmission sends oil to both motors and demands maximum stroke to travel from 0-16kph, before isolating one motor and then using 100% oil flow through the remaining motor to propel the machine to its maximum travel speed of 42kph. ZF said radial motors afford a

Dressta is offering improved versions of its 560E and 555C Extra wheeled loaders, with new Cummins diesels. Power for the larger 560E Extra now comes from a Cummins QSX15 diesel rated at 319kW, compared with the 310kW of the previous engine in this machine. The six cylinder Cummins engine drives through a torque converter, a three-speed, full powershift, countershaft transmission, front and rear axle drives and conventional differentials.
