Hydraulic crawler drilling rig

 Drilling feature1.The Rugged track of the drilling rig was driven by hydraulic motor with high traveling ability.2.The feed and rotary head were driven by hydraulic motor, therefore, the air and oil consumption and total drilling cost are lower.3.The hydraulic feed and rotary head of the drilling rig put out the biggest feeding force and largest rotary torque, which makes it more suitable for operation in complex worksites.4.The compressor equipped for the drilling rig is smaller and cheaper than that one the air rig equipped, along with the best price-performance ratio than air rig.5.The carriage with rollers provides for minimal wear to the drilling guide.6.The diesel engine and main hydraulic parts adopt imported products or famous domestic companies.7.The special compensation device makes a full protection of drill rod threads.Drilling specification
