DC SERIES COMPACTORS

DemaRock Compactors are high-quality hydraulic material compactors at an affordable price. Robotic manufacturing processes and quality parts are used to manufacture DemaRock Compactors, so they are built to last. Comes in various sizes and power outputs which can be coupled with specialty top-mounts on request so that it’s easier to switch between attachments at the job site for the machine operators.

These compactors feature through-bolted frames for maximum frame strength, heavy-duty hydraulic cylinders with a spring return mechanism for even wear, and a powder-coated paint system to protect against rust and corrosion. Oiling systems are built into the compactors to provide long-lasting working hours and keep the job-site humming.
