Product Description

The JUD350 underground core drilling rig adopts a modular structural design that separates the rig body, power unit, and control system for convenient transportation and underground assembly. The hydraulic system is driven by an explosion-proof electric motor, providing stable rotation and feeding performance. With an adjustable mast and swinging arm structure, the rig allows flexible drilling angles from horizontal to vertical positions. Its wide rotary speed range and reliable hydraulic components ensure efficient and stable drilling performance in underground exploration projects.

Full Hydraulic Drive System

The JUD350 adopts a full hydraulic drive system powered by an explosion-proof electric motor. The hydraulic pump drives the hydraulic motor to rotate the drilling head while the feed movement is controlled by a cylinder and chain double-speed mechanism, ensuring stable and efficient drilling performance.

Modular Underground Design

The rig features a modular block structure that allows quick disassembly and transportation. This design makes the drilling rig especially suitable for underground environments where equipment must be transported through narrow tunnels and installed quickly.

Multi-Angle Drilling Capability

The swinging arm and adjustable mast allow luffing movement to support multi-angle drilling. The rig can perform horizontal, inclined, and vertical drilling operations, making it suitable for various underground drilling applications.
