Tunnel Crawler Hydraulic Electric Roadheader
Tunnel Crawler Hydraulic Electric Roadheaders are indispensable equipment for infrastructure construction for road tunnels, railroad tunnels, dam headrace tunnels, coal-mine drifts, etc.
We developed various tunneling and mining equipment based on our great experience in coal mining. Nowadays our equipment is widely used in various fields all over the world.
Our everyday technical innovation contributes to the efficiency of our equipment. We are proud of our equipment's contribution to the improvement of infrastructure not only of China but also all over the world.
1. With interior spray and exterior water spray system to reduce the dust
2. Small diameter cutter, bigger force on the simple teeth. The layout of the teeth is reasonable, more easily to break rock and get through the fault, with less vibration and better stability.
3. Swiveling and lifting or lowering of the cutter can be achieved simultaneously. Curve cutting can be achieved.
4. Imported hydraulic elements
5. Separate loading and conveying motors, better loading capacity
6. Power pack for the roof bolter can be mounted by request to drive the roof bolters
Product Features:
1. Large positioning and cutting range and optimal machine stability.
2. The optimized cutting head arrangement of cutting heads makes the cutting forces more stable and the impact smaller, the cutting efficiency is increased by 20%, and the cutting consumption is reduced by 20%.
3. The flexible connection technology is adopted between the cutting motor and the cutting reducer, which has eccentric compatibility, which solves the problem of eccentric damage to the reducer and the motor due to rigid connection.
4. The cutting head, shovel board, first transport and other parts that are most prone to wear use high-strength composite wear-resistant plates, which have a life span more than ten times that of ordinary steel plates.
5. The receiving device adopts multiple anti-seize measures:
6. The design of the dual cooling system of the hydraulic system and wind water can ensure that the oil temperature of the hydraulic system is below 70 ° C, which can meet the long-term continuous cutting operation.
7. variable pump system, using load-sensitive multi-way valve, the hydraulic system generates less heat and improves the service life of seals.
8. The cutting motor self-circulating cooling system is innovatively configured to ensure that the equipment can still work normally without receiving external water.
9. Intelligent and safe electronic control system
10. Large air volume airborne dust removal system, environmental dust removal efficiency> 90%
