Introduction
HFU-4A full hydraulic tunnel drilling rig is mainly used in coal, geology, metallurgy, engineering and other industries, and is used for large-diameter gas pumping boreholes, water injection holes and large-diameter horizontal drilling construction in mines, tunnels, coal mines. It can meet the requirements of large-diameter cone drilling, large-diameter cemented carbide drilling and percussion rotary drilling.
Features
-
- 1 Independent structure, small size, light weight, flexible movement and easy operation.
- 2 The hydraulic pump is driven by the explosion-proof motor through the operating system, and then the hydraulic pump forces the hydraulic motor to rotate the drill bit, and at the same time realizes the movement mechanism of the drill bit through the cylinder and chain double speed.
- 3 The hydraulic chuck can meet the functions of shackle and power-off protection.
- 4 The sliding and telescopic function of the mast makes it convenient for the bottom of the mast to touch the ground or platform, making the drilling rig more stable.
- 5 The swing arm and mast can be used for luffing movement to meet the requirements of multi-angle drilling.
- 6 The spindle speed range is large and the torque is large.
