WHB 20 Long Pile driver

WHB 20 Long spiral rotary drilling rig 1.Stable and reliable; 2.High efficiency; 3.Strong overload capacity

 WHB Long spiral 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.
