Performance Characteristics

It adopts dedicated H-type hydraulic retractable crawler chassis and large diameter slewing bearing.

Chassis with swing legs to aid Disassemble. Imported Cummins electric control turbo-supercharged engine is used.

It complies with Euro IIl emission standed.In addition,it has strong power,which is sufficient to satisfy the construction on the plateau.Its noise is up to the national standard.

It adopts the single-rope main winch structure, the main winch rope at full drilling depth 132 m status can meet single-rope winding ,effective solution to the problemto which "Bite the rope" ,to greatly prolong the service life of steel wire rope.

Normal mode and entering-rock mode of unit head are available for operation in soil and rock to improve the construction efficiency.

Power head with automatic rotation,in normal mode and entering-rock mode rotating speed continuously adjustable.

It is equipped with a centralized lubrication system as standard configuration: maintenance is easy.
