Structure Features
This trailer mounted drilling rig is applied to drill by forward and reverse circulation. It is characterized by easy operation, great drilling capacity, convenient assembly, disassembly and maintenance, strong practicality, compact structure, stable transmission, durable and solid, low operating cost and so on. It can screw and unscrew the drilling tools by machine. Hydraulic system is mainly used for supporting the trailer, lifting and lowering the mast. The trailer can match with a variety of tractors. It adopts front single-bridge and rear double-bridge structure, which is suitable to travel in the desert. It is fitted with turnplate type traction frame, dual-pipeline air brake and five hydraulic legs. The drilling rig can be leveled conveniently and quickly.
