The machine lock bar rotary drilling rig uses hydraulic crawler-type telescopic chassis, self-lifting and folding collapsible drilling mast, telescopic drilling rod and many other technical applications. It is a construction machine suitable for hole formation in building foundation engineering. Mainly suitable for the construction of soil layers such as sandy soil, cohesive soil, silty soil, etc., it is widely used in various foundation constructions such as cast-in-situ piles, continuous walls, and foundation reinforcement.

Compared with ordinary rotary drilling rigs, machine-locked rod rotary drilling rigs have many objective advantages, such as the ability to drill through special grounds such as cement ground, hard sandy soil layers, and rock layers. It is suitable for large-scale engineering construction, buildings, high-speed, high-speed rail 3. Railway engineering construction. The machine construction runs fast, has high efficiency, good drilling quality, and is fuel-efficient and durable.
