.WHL series crawler type long rotary drilling rig specifications
Pile machine is ideal equipment which is widely used in building residential high-rise buildings, highways, high-speed
railway foundation treatment .
Rotary drilling rig get rid of the cable tie and mobiles flexiblly, wide pile diameter, high
efficiency.
Walking stability, operation safety:Electric caterpillar design;large size grounding , small ground pressure, before and after pile machine is equipped with 4hydraulic legs; construction stability.
Flexible walking, high construction efficiency:Driven by the motor,big torque reducer to solve the walking difficulties caused by uneven muddy of construction site, the efficiency can be improved 2-3 times, no pile position dead angle, pile.
Aligning with the pile location is accurate and reliable:Braces adopt screw expansion which can be realized adjustment on the pile and column verticality , ensure pile vertical, accurate and fast.
Simple repair , cost-effective:The malfunction rate of the motor and the repair cost is much lower than that of diesel engine, no noise, no waste water discharge.
Can achieve a variety of constructions.Can realize the SMW process, multiple spindle drilling machine, diesel hammer, hammer, hydraulic hammer and other working apparatus for multiple method construction
