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.
The five new compact-radius Caterpillar E Series Mini Hydraulic Excavators are equipped with a new digital COMPASS—Complete Operation, Maintenance, Performance, and Security System – control panel. Built into the COMPASS monitor are an anti-theft system, requiring a five-digit alphanumeric password to start the machine, and an Economy Mode feature (3.5 to 5.5tonne machines) which, Cat says, can potentially lower fuel use up to 20% by adjusting engine speed.
JCB is introducing new hydraulic breakers to meet a range of customer needs. The larger HM870Q, HM1270Q and HM1570Q hydraulic breakers feature stainless steel components in critical areas as well as sealed for life accumulators, both of which boost operating life. Performance has been increased due to improved hydraulics, boosting efficiency and reducing noise while the breakers are said to have high power to weight ratios compared with rival units.

The XGMA Machinery Company, based on the tourist island of Xiamen in southern China, is planning to expand its operations worldwide. Founded in 1951, the company produced its first wheeled loader in 1964, and said it was the first Chinese manufacturer to sell more than 10,000 wheeled loaders a year. Today it sells more than 30,000 units/year and has an impressive portfolio of products, which also includes hydraulic crawler excavators; road construction equipment (including compactors, dozers and milling mac
