XTR7/360 TunnelRoadheader XTR7/360Boom-Type Tunnel Roadheader is equipped with cutting structure and a supportingstructure, a control table, body assembly, walking institutions, hydraulicsystem, spray dust removal system, electrical system, lubricating system, aguard board assembly, identification and coating, cooling system, a shovelplate assembly, first transport, second transport. The machine has high safetyand reliability.
Optimizationdesign of large span cutting arm, a small diameter single helix hard rockcutting head, cutting height can reach 7.2m, the effects of materialcollecting, stronger rock breaking capacity. Equipped with automatic roll cablecontrol system to avoid the damage of the cable, improve work efficiency.Double layer detachable frame and the split type rotary table, convenientinstallation, repair. Use air cooling, cooling effect is good, in the absenceof external water source, the host can work properly. With remote control,remote control of equipment can be realized, and the personal safety andmachine equipment can be effectively protected, improve the safety and workingefficiency.
