Product Description

DR-285 core bore drilling machine for sale --He is a multi-purpose strong power rotary pile driver, which can be widely used in a variety of working conditions. Optional equipment Weichai, Cummins brand engine, Kawasaki hydraulic system, DOOSON rotary reducer, etc. This type of rotary digging machine can be used with different types of drill bits, which can be selected according to the construction environment and engineering needs. For example, when the surface layer of the construction site is concrete and the lower layer is an ordinary sand layer, you can first select the spiral hole drill to drill the hole, and then perform the drilling and drilling construction. When the construction site is hard soil, water can be injected with a small-diameter bidirectional open barrel drill bit. When the drill reaches the required depth, the hole expansion operation can be carried out according to the required width. The drill rod of this rig is Kelly rod, which can be customized according to customer requirements
