Tunneling Roadheader Machine Underground Working
The Roadheader is a continuous mining and tunneling machine that can economically excavate a wide range of rocks. The Road Header can be used for building mine entrances, galleries, tunnels and for mining coal and ore.
The Tunneling Roadheader does require a greater investment than an excavator with a roadheader attachment. The excavator’s performance, however, is limited because it is dependent on the hydraulic power capabilities of the excavator. Attachments are extremely flexible in large tunnels for scaling, cutting manholes, corners and excessive grouting. A disadvantage of using an excavator with roadheading attachments is its inability to remove muck simultaneous to cutting; it must be stopped and moved in order to clear muck, which results in a reduced production rate, which includes cutting the material as well as moving it behind the machine.
Suitable for the tunnengling of coal tunnels and mixed coal-rock tunnels construction, also can be used in the tunneling of railway, highway and water projects.
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%
