4.Advantages ：
(1) Powered by three sets of importedgasoline engines, powerful, low fuel consumption, long life.
(2) Imported air compressor, small, light,large displacement and high efficiency.
(3) Extension air pipe, quick jointconnection, one transmission can complete two drilling operations.
(4) The handle controls the rotation,drilling and lifting actions.
(5) The hydraulic system is equipped withload sensitive device, which improves the cutting ability of the drilling rig,reduces the heating and improves the life of the system.
(6) The oil pump and the oil motor have noradial load, to improve the bearing life and reduce the sealing wear
(7) The swivel head has compact structure,light weight and high torque, and is suitable for drilling in
competent formation
(8) Hydraulic transmission part of thepipeline using fast joint connection suit for installation, removal conveniencein field and reduce pollution.
(9) Adopting the combined frame structure,each main component is respectively arranged in the frame, and can be carriedseparately, the largest single piece is not more than 100kg, and the wholemachine weight is about 750KG.
(10) The base has the advantages of simplestructure, convenient adjustment, fully self-locking and good stability.
