XCMG Official Tunnel Roadheader XTR7/260

XTR7/260 Tunnel Roadheader

XTR7/260 Boom-Type Tunnel Roadheader is equipped with cutting structure and a supporting structure, a control table, body assembly, walking institutions, hydraulic system, spray dust removal system, electrical system, lubricating system, a guard board assembly, identification and coating, cooling system, a shovel plate assembly, first transport, second transport. The machine has high safety and reliability.

Optimization design of large span cutting arm, a small diameter single helix hard rock cutting head, cutting height can reach 7.2m, the effects of material collecting, stronger rock breaking capacity. Equipped with automatic roll cable control system to avoid the damage of the cable, improve work efficiency. Double layer detachable frame and the split type rotary table, convenient installation, repair. Use air cooling, the cooling effect is good, in the absence of external water source, the host can work properly. With the remote control, remote control of equipment can be realized, and the personal safety and machine equipment can be effectively protected, improve the safety and working efficiency.
