The ZT-3500 Horizontal Directional Drilling Rig is divided into three blocks: frame, power station, traveling pump station.

The ZT-3500 Horizontal Directional Drilling Rig is divided into three blocks: frame, power station, traveling pump station. The motive is provided by the Cummins engines and two set of independent hydraulic system are driven by two diesel engines which have a stable performance and is convenient for movement. Hydraulic parts choose American SAUER main pump and motor, adopt the rack-and-pinion trust drive with four motors driving, high horsepower electronically-controlled. The pullback forces can be set steplessly. The thrust speed is 0—20M/min.The rotary drive is driven by four motors, it is closed system, torque can be set, self-breaking. The power station is assembled to the Drill with operating cabin,air-sonditioning.5T hydraulic crane. Steel track chassis.
