New pivot steered rollers from Hamm

The company claims that the machines deliver high-quality compaction and is offering an array of variants to suit different customer requirements. Models are offered with split and non-split drums, as well as oscillation and combination variants.

An integrated automatic reversing system is fitted that brakes and then accelerates the rollers quickly and smoothly. The electrically-adjustable seat also turns to face the direction of travel automatically. Other features include the firm’s Smart Compaction Assistant that helps optimise compaction as well as a high visibility cab that includes a window in the floor for a better view of the drums.

Komatsu’s D71-24, its biggest hydrostatic dozer

Even for its size, the EU Stage V emissions compliant dozer offers unrivalled visibility with its distinctive super-slant nose, razor sharp response, heavyweight performance and lightweight consumption.

Operating weights of the D71EX-24/PX-24 range from 22,600-24,000kg with blade capacity up to 5m³ and the Komatsu engine puts out 179kW of power at 2,100rpm.

The dozer’s Parallel Link Undercarriage System features rotating bushings to help minimise maintenance downtime and cost of ownership. EXi and PXi versions benefit from second generation Intelligent Machine Control, the iMC 2.0, that continuously scans the jobsite and uses the data to plan the next pass.

It comes with ergonomic one-touch controls to allow any operator to drive like a pro.

Compact but productive soil compactors from Ammann

The machines have a novel design with no rear axle, a configuration that allows a low mounted engine, lowering the centre of gravity and improving stability even on slopes. The design also allows for good operator visibility as well as high manoeuvrability for the machines.

In the cabs the machines have adjustable seats and vibration-isolated platforms, a robust dashboard and a multi-functional control display.

The drums are designed to be maintenance-free as part of Ammann’s ECOdrop philosophy, reducing the cost of ownership.
