Good vibrations at Bomag: Bomag tops off reversible plate compactor line; largest model to date.

[ILLUSTRATION OMITTED]

Bomag has introduced the largest model in its reversible plate compactor lineup with the new BPR100/80D model. This 1570 lb. compactor is targeted toward the compaction of granular, cohesive or mixed soils, providing a frequency of 3360 vpm at 56 Hz.

The BPR 100/80D plate compactor is powered by a Tier 4 single-cylinder Hatz 1D 90Z diesel engine rated 14.75 hp at 2600 rpm. The engine is air cooled and equipped with a 2.6 gal. fuel tank.

Vibration on the compactor is V-belt driven off the engine to a shaft with an eccentric weight. The shaft is connected through gears to a second shaft, which counter-rotates the eccentric weight to vibrate the plate.

To move the compactor forward or reverse, the position of the eccentric weight is hydraulically adjusted, powered by a Jihostroj pump through Argo-Hytos valving.

Maximum frequency of the BPR 100/80D model is 3360 vpm with a centrifugal force of 22,500 lb. Maximum working speed on the machine is 88.6 ft./min, with a 35% gradeability, said Bomag. The speed, vibration frequency and centrifugal force of the compactor are adjusted through the throttle control.

Bomag has integrated its Economizer system into the compactor for soil compaction status. By detecting the soil stiffness, the Economizer system helps the operator determine soft spots or detect overcompaction. This is designed to allow a job to be completed with 25% fewer passes, using less fuel and reducing machine wear, said Bomag.

A tip control system has also been integrated into the machine to allow easier direction change, increasing machine handling. Operator comfort is gained with the built-in vibration buffers in the steering rod, which reduce the amount of vibration transferred to the operator. The steering rod is height adjustable and lockable in both the transport and working position.

Construction of the BPR 100/80D reversible plate compactor incorporates a high-strength, grain-refined steel hood to protect the engine and other internal components from damage. The hinged hood swings forward for easier access to the engine and other maintenance points.

The BPR 100/80D compactor has dimensions of 42.5 in. high by 31.5 in. wide by 74.4 in. long. Without extension bars, the machine compacts to a 25.5 in. width. It is manufactured at Bomag's Boppard, Germany, facility.
