Piling Rig

Description

A piling rig is a construction machine for piling in foundation engineering. Foundation pile drill rig is mainly applied to drill in sandy soil, clay, salty clay, etc to provide the foundation support to buildings or others. It is also an ideal product for bridge, port and railroad worksites. The piling rig (foundation pile drill rig) consists of unit head, rotator, winch, clutch, speed control system and oil pump as well as diesel engine.

Feature of Foundation Pile Drill Rig

The piling rig can offer increased productivity and versatility. Foundation pile drill rig is multi-functional, i.e. it can conduct pile driving, extracting, and static pressing operations. It has strong torque and high drilling efficiency because of its ability to drill precisely. The range of its rotary speed is pretty wide. Foundation pile drill rig can be hydraulically pressurized or depressurized to conduct the drilling. The piling rig has easy transportability, exceptional stability, and operational safety. It is an ideal choice for foundation contractors across the globe.
