New soil compactors from BOMAG offer increased performance
Boppard based Bomag is unveiling its new 5-8tonne class soil compactors, which are said to offer increased performance and lower running costs. Compact, manoeuvrable and economical the BW145 and BW177 machines are said to be highly productive and suited to use on small-medium size projects. High performance is claimed for compaction, gradeability and efficiency and Judith Rheingans of the firm said, “The operator platform has been redesigned to give better visibility and access. The operator can see the drum better.”

A key point is the upgrade to the vibration system, which is said to reduce the risk of drum bounce. In addition, the machines have a sophisticated automatic amplitude control, BOMAG VARIO CONTROL, which is said to makes the compactors more suited to compaction duties in sensitive areas. Fuel economy from the new Tier 4 Interim/Stage IIIB engines has been by up to 30% improved too, with help from an integrated ECOMODE function that allows the machine to match engine speed to work load intensity. An engine stop function also switches off the engine after a pre-set idle period, further reducing fuel consumption. Another improvement in efficiency comes from the new dual circuit drive system, which features twin pumps for the front and rear axle that improves traction. These new BOMAG single drum rollers can tackle up to 56% gradients forwards or backwards.

Ergonomics in the cab have been improved also, along with better visibility. The sophisticated BOMAG VARIOCONTROL is said to make the machines easier to operate and also helps optimise compaction performance. Other features and improvements include easier transport as the rollers are just 2.65m high and are equipped with tie-down rings so that they can be secured when carried on a truck or trailer. A dozer blade with manual control is offered, which is said to be more precise than the earlier foot-controlled blade. And maintenance is said to be easy with grouped service points that are accessible from ground level.
