Description

XFS300 type crawler drilling rig is hydraulic controlled. It is a new type crawler drilling rig which has a wide application scope. It can be used for drilling water well, monitoring well and geothermal well. When drilling into rocks, down-the-hole hammer is used. Air is used for draining slag. The penetration efficiency of this rig is dozens of times that of conventional rotary drilling rig.

Features

1. This crawler drilling rig is equipped with tracked chassis. It has high off-road performance.
2. This crawler drilling rig has a modular design which makes the transportation very convenient.
3. The locator is capable of adjusting and changing the locating plate according to the types of drill pipes and impactors.
4. The rotary unit of the crawler drilling rig is reversible. The hoisting height is more than 6 m. It is very convenient for drilling underground.
5. The winch has good performance in lifting drill rod and hammer. It ha reduced labor intensity.

Application Scope

XFS300 type crawler drilling rig is widely applied to in industrial and agricultural water conservancy projects, such as water wells, monitoring wells or other exploration boreholes. Particularly, this crawler drilling rig can be used for the exploitation of geothermal heating.
