Additional informations

HP55 mole is designed for hand installation of small diameter pipes and cables.

This mole is characterized by high accuracy, low weight and low air consumption. It's handy and comfortable to use.

Reverse gearis switched on by pulling the air supply hose. Easy and safe switching of operating mode allows efficient piercing and also allows to quickly reverse the mole in emergency situations. Very important factor is that switching reverse mode on doesn't require turning air supply hose which might be difficult. Sometimes it might not even be possible due to lack of stiffness of the air supply hose when mole is far deep in the soil from the entry pit.

HP55 semms to be necessary in urban works in telecommunication and electrical installations. 55mm pierced hole allows 40mm pipe installation in stable soil only. In less stable ground it might be succesful only on short distance.
