20 ton pusher

20 ton Compact Crawler

Heavy duty, lightweight!

Our 20 ton CPT pusher unit is a perfect choice if you need 20 ton push capacity from a small and flexible yet affordable machine!

The machine offers 20 ton push force with a weight well under 1000 kg, so you can tow it on a trailer be- hind a regular car. Small dimensions enable access to narrow places. Anchoring the machine using the two augers is easy in most types of soils. Auger extension rods can be added. The rod rack can store up to 40 1m rods.

The machine is intended for CPT and Vane shear test. Push functions can be controlled from the manoeuv- re pulpit or by using levers mounted on the hydraulic valves. In automated CPT mode the probe is pushed with constant speed (0-40 mm/s) regardless of ground resistance.

Wide belts make it suitable for tasks where the ground is soft and this also minimizes ground damage on e.g. lawns. If you need to traverse very slippery ground the belts can be provided with spikes.

When you relocate the machine you use the handle bar to steer it. Pull the handle bar to the right to turn right and vice versa. On the handle bar you also find the throttle, an emergency stop and a parking brake.

The pusher is developed and manufactured in Sweden.
