Lockbar rotary drilling rig for crawler machine 28m rotary drilling rig drilling depth

With hydraulic crawler retractable chassis, self-lifting and falling foldable drill mast, Telescopic drill pipe, rotary pile drilling rig with circular power rod is a kind of construction machinery suitable for drilling in building foundation engineering. It is mainly suitable for the construction of sandy clay silty soil and other soil layers. It is widely used in the construction of cast-in-place piles continuous walls foundation reinforcement and so on.

Compared with the ordinary rotary drilling rig, the rotary pile drilling rig with circular power rod has many objective advantages, such as drilling the concrete ground, the hard sand soil layer, the rock layer and so on. It is suitable for large engineering construction, high speed rail and railway construction. The machine works with fast speed, high efficiency, good drilling quality, oil saving and durable.
