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, cooling effect is good, in the absence
of external water source, the host can work properly. With 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.
