Rock Wheels

Rock wheels is a powerful excavation tool, used in noise and vibration sensitive areas.

Our range of Erkat Rock Wheels offer more accuracy than breakers and are ideal for trenching in hard, rocky conditions. They can also be used for tree stump removal.

Unlike other rock wheels, the Erkat rock cutters have the motor mounted on the side and not contained in the rotating drum. This patented design means the motor is protected from unnecessary damage.

Astra Site Services are the UKs sole distributor for Erkat rock cutting products.
