overview

Application

It's applicable for pipeline construction about Municipal Construction (Electric,Communication,Water Supply) and Natural Gas,Oil Delivery. 

Technical Features

1. The high and low speed push-pull rotation system, the variable plunger motor realizes the high and low speed push and pull of the power head, which increases the adaptability of the drilling rig's working conditions and improves the construction efficiency of the drilling rig;

2. The whole machine adopts seat switch, logic interlock, and optional wire-controlled proportional walking, electric shock protection, instantaneous force increase 20% and other innovative technologies;

3. The push-pull rotation adopts multi-gear output technology, and the engine adopts high-pressure common rail and fully electronic control module technology, which saves energy and construction efficiency, and the construction efficiency is increased by 15%;

4. The whole machine has a wide field of vision, single/double handle mode, wire-controlled proportional walking system, comfortable, efficient and safe operation.
