The HiSpec Kompactor is a multipurpose trailer. It’s unique compaction and off-loading mechanism makes the Kompactor ideal for transporting and off-loading any material. Due to its unique compaction the payload can be increased by as much as 40%. The Kompactor is available in four sizes, from K30 (18ft) to K40 (24ft). As standard the HiSpec Kompactor is equipped with commercial running gear, super single wheels, air over hydraulic brakes and a hydraulically sprung drawbar for a smooth ride.

Greater Capacity

On the move compaction is one of the key traits of the Kompactor. It introduces advanced efficiencies to the market through its dynamic compacting system. Its ability to compact the load results in a larger payload. Depending on the material the payload can be as much as 40% leading to transport and fuel savings. The Kompactor can be used to carry a wide variety of materials

Unload Safely

Using a dynamic moving headboard the Kompactor can unload in as little as 40 seconds. It offers a much safer alternative to the traditional tipping trailer as there is no requirement for the trailer to tip. This removes the long-standing risk of overturning on poor or uneven ground and provides the added advantage of being able to unload in low buildings.
