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.
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

A full range of pavers, featuring both tracked and wheeled undercarriages, also will be at the show. The display includes the new AP255E, which is the smallest paver in the range, and the new AP1055E, the largest paver in the Cat range.
Ammapax is the simple and cost-effective solution from Ammann to suppress noise levels for those operating plants close to residential areas. Available in three different designs that can reduce noise pressure levels by up to 10 dB, 15 dB and 20 dB, the Ammapax does not require any additional installation space, as it is lowered into the mixing plant’s chimney and fixed to the chimney opening using four bolts. It can also be used in third party plants, said the company.
