The 4900lbs (2223kg) Ho-Pac 4000 is ideal for trench, slope and excavation compaction, and provides effective forces for driving pilings, posts, pipes, beams and sea walls. Compatible with carriers in the 77 to 150 ton range, this attachment is designed for use in large excavators, loaders and backhoes.

The Ho-Pac 4000 features Four Function Valve that controls flow, pressure, regenerations and oil flow direction, Oil Splash lubrication providing maintenance free (no greasing) bearing lubrication, and tough coat hoses that prevent cuts and extend wear life. Larger eccentric with mass further away from shaft centerline helps to increase impulse force.
