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 ‘world’s smallest crusher bucket’, the MB-L160, made its debut at INTERMAT on the MB stand. Weighing just 1,350kg, the 0.3m3 capacity bucket has a throughput capacity of up to 22.5tonnes/hr and fits to machines between seven and 12tonnes, including backhoe loaders. Product size adjustment ranges from 15mm to 50mm.
Caterpillar Paving intends to increase sales into the soil compaction sector with its B-series CS and CP single drum machines. The CS68B and CS78B are smooth drum machines while the CP68B and CP78B have a single padfoot drum. The CS68B and CP68B compete in the 14tonne class while the larger CS78B and CP78B are 17tonne class compactors. The machines all share features such as the new high comfort, high visibility, climate-controlled cab.

AFW350 and AFT350 are the latest medium-sized asphalt pavers from Ammann and are said to offer good manoeuvrability in confined areas. The hydrostatically driven machines offer a paving width from 1.8-3.5metres and the output potential of up to 230tonnes/hour. A wide range of optional equipment is available to improve paver performance. These include a vibratory screed or a tamping/vibratory screed that can be heated with either gas or electricity, and automatic lighting and temperature control functions.
