XTR200R Boom-type Tunneling Boring Machine is a kind of tunneling equipment for hard rock with the function of cutting, loading and spraying for dust suppression. This machine is suitable for tunnel rock construction. High configuration is used in this machine. Key components adopt locking connection between themselves so that they are reliable.

Electrical control system
Electrical control system can control the start and stop of every electromotor. It provides control signal and has the function of low voltage creepage protection. It also has the function of oil level and temperature detection, electromotor protection, showing the running state and failure message of electromotor.

Hydraulic system
The hydraulic system has the function of constant power, pressure cut off and load sensing. The system adopts bypass-valve technology to increase service life of components. Key components of hydraulic system are international famous brands.

Spray system
Adopting 3-ring water dust suppression so that ifs effective to cool and suppress dust. Installation of draught fan is reserved. Ventilation and dust removal system is "far-press" and "near-inhale".

Cutting mechanism
Cutting head can be changed by ordinary and hard rock working condition. Pick configuration technology comes from Kennan matt USA. Reasonable arrangement brings powerful tunneling ability. Pick can choice between Kennan matt and SANDVIK.

Shovel Board
Main shovel board adopts locking connection. Top board adopts replaceable chrome steel wearing plate and adapts to hard rock better so that service life can be improved.
3 loading width are optional to adapt different tunnel condition.

Walking mechanism
Large displacement motor and walking reducer are imported. Walking mode adopts rollers-rolling to improve walking ability.
