HYG-2 full hydraulic engineering exploration drill

A. General Introduction: HYG-2 full hydraulic engineering exploration drilling rig is mainly applied in the fields of buildings, high roads, bridges, water conservation, hydroelectric power, mines and tunnel construction and other industries. It is used for drilling of foundation surveying hole, deep foundation pit anchor hole, foundation, road, as well as dam strengthening hole, water drainage hole, quarry hole, small water well and engineering hole. B. Main Structure and Features: 1. Fully hydraulic driven, integrated structure with steel crawlers. 2. The main crane arm is in the function of lifting, lowering, swinging, extending and retracting. 3. The mast and mast sliding seat can swing simultaneously with the help of hinge seat mechanism. 4. The mast could do forward & backward movement and side-swing on the mast sliding seat. 5. The drill head is driven by oil cylinder & chain double-speed mechanism, besides, it is with dual-chain balancing mechanism. 6. The drill head has the following functions: a. Oil cylinder turnover b. Spindle floating c. Sliding clearance compensation and adjustment d. Dual-motor with low speed and big torque e. Top drive f. Integrated water swivel structure 7. With perfect function of shackles of drill rod. 8. With integration arrangement of hydraulic system, electric system and mud pump and concentrated and convenient operation function. 9. The overall unit is compact in structure, complete in function, light in weight and flexible in movement. C. Main Technical Specifications: 1. Drilling depth: 150-280m(492-918 feet) 2.
