Envi 20 ton cone penetrometer pusher

Our CPT pusher unit is a perfect choice if you need 20 ton pusher capacity from a small and flexible yet affordable unit. The pusher is small enough to be transported on a pick-up truck or on a trailer. The anchoring system operated by two persons will anchor the pusher in all types of soils. The two hydraulic cylinders have a stroke of > 1 m so you can push 1 meter rods in one stroke. The pusher is manufactured in Sweden. This pusher is the second generation pusher sold by Envi. It succeeds the successful pusher manufactured in Thailand that was earlier resold by Envi.
