Product description

Pneumatic piercing tool (with reverse mode) complete with active head designed for horizontal operations.


Additional informations

HP55R is designer for hand installation of small diameter pipes or lines. Thanks to active head innovation we've managed to improve accuracy and speed during piercing. Additional advantages are low weight and low air consumption. This hammer is very handy and easy to manoever when space for excavation is limited.

Reverse mode is switched on by pulling the air supply hose out (there is no need to turn the 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 be possible due to lack of stiffness of the air supply hose when mole is far deep in the ground from the entry pit.

Ther is an option to use calibrator in the first operation but this option reduces piercing speed by approx. 30%.

Use of HP55R mole is essential for the instalation of electric and telecommunication networks.

We do not recommend to pierce very wet soil. In such conditions stee pipe ramming is recommended. Unfortunately HP55R due to low power isn't suitable for pipe ramming. Active head doesn't allow to use expanders either.

It is not recommended to work with the mole in marshy ground. In such condition it is advised to ram steel pipes. HP55R mole due to low impact power and active head isn't adapted for pipe ramming and use of expanders.
