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.
Case’s 12.2tonne 621F wheeled loader will make its first appearance at a European show during bauma. Powered by a second generation common-rail Tier 4 interim engine and benefiting from the use of fuel saving SCR technology, the 621F is said to have proven ZF auto powershift transmission and heavy duty axles. The model is also equipped with a 100% locking front differential for maximum traction and reduced tyre wear. Similar to other larger Case F Series wheeled loaders, the 621F has a cooling pack directly

Hydra shearer drums, now part of the ESCO family of mining products, have been engineered with radial-style picks and tool holders that are recessed into the vane to deliver optimum cutting performance. The result is reduced wear on the drum, increased product size and lower power consumption. The range of shearer drums can also be equipped with conical style picks.
