We sell two main classes of product, the first is leader mounted pushing systems.
This product is a semi-permanent fixture of your fixed leader rig and employs the crowd force of the rig and hydraulic rams to push in or extract boxed sheet piles or single large piles without percussion noise or vibration.

Our second class of extractor are ground mounted static machines of 400 tonne or 1,000 tonne capacity. These are sited on a flat level surfact next to the pile and simply use massive jaws and hydraulic rams to extract piles.
These has been used with great success on very large piles in very unattractive ground conditions, such as London clay.
