Product Features
The RCH - 4A fully hydraulic underground drilling rig significantly improves the optimization of volume and weight with its separate structure, making it lightweight, portable and easy to operate. The explosion - proof electric motor - driven hydraulic pump ensures stable rotation of the drill bit, while the two - speed mechanism enables efficient feeding of the drill bit. The locking and power - off protection functions of the hydraulic chuck enhance operating safety. The sliding and telescopic design of the derrick, combined with the lifting and lowering movements of the swing arm, enable the drilling rig to flexibly drill at multiple angles. The spindle ' s wide speed range and large torque enable the drilling rig to adapt to various geological conditions, ensuring the efficiency and success rate of operations.
