Six new hydraulic compactors have been designed for use on carriers in the 2,205- to 88,185-pound class by Atlas Copco Construction Equipment.

Atlas Copco claims that the compactors are virtually maintenance-free due the company’s PermaLube system, which keeps the bearing flooded with lubricating oil. The integrated control valve regulates hydraulic flow and pressure to prevent motor overload, particularly if compactors are used on different carriers.

According to the company, a key design feature of the compactors is that the housing attachment is offset at 15 degrees, improving the force distribution on the vibrator plate, while further reducing the stress and wear on the compactor.

The hydraulic motors are protected by a regeneration feature that allows the unit to be connected to a uni-direction or bi-directional circuit.

The new Atlas Copco compactors are easy to attach; no special mount is required for fitting to carriers, the company says. Standard adapter plates and attachment brackets make attaching the compactors to carriers simple. Atlas Copco also can custom-make plate extensions to fit specific applications.

Optional backfill blades make compactors easier to use by leveling the way, enabling work to progress smoothly while deflecting material.

The new range of compactors is ideal for compacting trenches, ground soil and embankments, as well as for driving and pulling formwork, posts and sheet piling, the company says.
