Pneumatic piercing tool (with reverse mode) complete with active head designed for horizontal operations.
Direct pulling pipe Ø50 and Ø63 behind the mole in the first operation.
Mechanical pulling pipes Ø40 and Ø63 in reverse mode
Ramming of Ø50mm steel pipes
HP75M mole is designed for hand and mechanical installation of plastic pipes up to 90mm diameter. Plastic pipes with 50mm & 63mm diameter can be installed directly behind the mole using dedicated pulling adaptors. The big advantage of this mole is high accuracy and low weight 32,5kg. As a result, HP75M is handy and comfortable to use. The main purpose of the device is to pierce holes for the installation of 63mm PE pipes. HP75M is also doing well with expanding the bore to 110mm in the second operation to allow 90mm pipe installation. Reverse gear is applied by pulling the air supply hose. Switching working mode enables easy operation and also the withdrawal of the mole in emergency situations. A very important factor is that switching reverse mode doesn't require turning the air supply hose which might be quite difficult. Sometimes it might not even be possible due to the lack of stiffness of the hose when the mole is far deep in the ground from the entry pit. We've managed to eliminate valve rubbers by implementing solutions from bigger moles (HP95, HP135, HP160). New construction of the controller with higher airflow has an immediate impact on the quality of operation, power increase, and efficiency while working in moist soil and clay. We will shortly be introducing the HP75MR model. Increased accuracy and speed of piercing will be the result of using an active head in this construction. The main purpose of this mole will be Ø63mm pipe installation. Active head guarantees to pierce with the highest accuracy. Active head works in 2+1 system which means that energy that comes from the first two impacts is used for breaking and pushing the soil away from the mole. The third hit pushes the corpse forward. As a result, the HP75MR mole is an accurate and very effective tool.
