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 BSC 1409 D from Putzmeister is a self-propelled concrete pump designed specifically for concreting drilled piles on unfinished surfaces. In contrast to using truck-mounted concrete pumps for concreting drilled piles, it does not need supports to be set up each time it changes location. Compared to concreting with a delivery pipe, placement speed with the tracked concrete pump is now said to be considerably higher.
Shantui’s SR12-5 road roller is the Chinese company’s most exported construction machine model and will be part of its large exhibition at INTERMAT. Said by Shantui to be designed mainly for use in mid-sized compaction duties, it features DANA hydraulic control systems, and comes with a single front-mounted drum.

Cat has added three new models of wheeled loader to its range, badged 924K, 930K and 938K.
All share the same basic architecture, differing in wheelbase, axles, machine width and bucket capacities – the latter extend from 1.9-5.0 cubic metres. The biggest change over the H-series models they replace is an all-new cab, offering a massive improvement in ergonomics and comfort. A wider, deeper front windscreen, climate control, seat-mounted joysticks and an ultra-low in-cab noise level of 66dB(a) are among i
