Hydraulic Crawler Drilling Rig With 110-219mm Hole Dia And single/ double motor
Full hydraulic crawler multifunctional drilling rig is suitable for different soil condition, for example gravel layer, hard rock, aquifer, clay, sand flow etc. This rig is mainly used for rotation percussion drilling and normal rotation drilling in the project of bolt supporting, slope supporting, grouting stabilization, precipitation hole and underground micro piles, etc.
Full hydraulic crawler drilling rig is configured with rotation-percussion rotary head or large torque rotation type rotary head as alternative, and equipped with down-the-hole hammer, which is designed for various hole forming operation.
Main Features of SM-300 hydraulic crawler drilling rigs
1. Multiple pumps and circums hydraulic system make the machine perdurable and stable with easy operation,lower~fault,clear oil circle.
2. The multiple circums hydraulic control system sharply reduce the use of electrical control units,so it can settle difficult problems of electrical control units being easy out of work and repairing trouble.
3. The engine matchs hydraulic oil pump perfectly, which can reduce the power loss,make the engine lowest consumption,in order to get energy-saving and effectively lengthen the service life of the engine.
