Underground Tunneling Drilling Jumbo
Description
Underground tunneling drilling jumbo is widely applied for construction of roadway, tunnel and culvert in mine, metallurgy, water, power, railway, highway and other projects. This underground drill rig mainly consists of rock drill, drill boom (the bearing, positioning and propelling mechanism), steel structure frame, traveling mechanism and other accessory equipment. This equipment supports several rock drills to work at the same time.
Features
1.The combination of drilling jumbo and slag loading equipment improves construction speed and working condition.
2.It uses drilling and blasting method for underground tunnel construction. Drill-blasting method provides favorable working condition for underground tunneling drill jumbo.
3.Its drilling speed is fast and energy consumption is low.
4.This underground drill rig features small size, compact structure, low center of gravity, high flexibility, stable performance and strong grade ability.
5.This underground tunneling drilling jumbo is configured with anti-jamming device, which features high reliability.
Parameters of Underground Tunneling Drilling Jumbo
Maintenance of Underground Tunneling Drilling Jumbo
A. Daily or Frequently Required Maintenance
B. Periodical Maintenance
C. Maintenance Adjustment on Particular Case
Sometimes we need to adjust the maintenance period and frequency in compliance with the different conditions like temperature, humidity and workload etc to better protect the machine.
