Description
CMZY series double boom loading, excavating, drilling and bolting machines have integrated mucking loader, single-armed (multi-armed) drill rig and conveyor, making them capable of drilling (including face drilling, blasting hole drilling, bolt hole drilling, long-hole drilling), as well as loading and conveying slags.

With characteristics of energy-saving, low noise, reliability and exceptional versatility, our rocking drilling machines have been developed for medium and small tunnel cross sections, hills with slope smaller than 22 °. These drill jumbos can also be used for tunnel excavation in non-coal mines, railway, hydropower projects, etc.

Advantages
Maximized versatility
CMZY series two-boom drilling jumbos increase productivity through its genuine adaptability to different working sites. The modular design enables this double boom drilling jumbo to operate in large tunnels (more than 5m × 5m).

Improved efficiency
Patented quick-changing device helps fast switch between bucket and breaking hammer. This can effectively reduce the time of changing device, thus resulting in enhanced efficiency.

Enhanced operator comfort
Modern and ergonomic cabin design brings improved operator comfort. With noise levels under 125dB at all times, this drill jumbo supplies a safe and comfortable working environment for the operator.

Advanced drilling and boom control systems
Optimized performance with amplified drilling automation has resulted from the use of EPEC control system. This is a well-proven and intelligent drilling control system with two alternative control methods: manual drilling control and intelligent torque control. Electronic monitoring of the entire drill jumbo and precise display of the drilling angle bring enhanced and maximized performance.
Simplified structure and reduced labor cost
Integrated design of drilling machine and mucking loader has simplified the overall structure and improved the reliability of system.

Reduced labor cost
Integrated design of this two-boom drilling jumbo allows reduced labor costs as fewer operator is required compared with separate design of drilling machine and mucking loader.

Maintenance
1. Keep the drill jumbo clean when running it, and keep daily and regular maintenance.
2. After using this double boom drilling jumbo, check if the handles are flexible and reliable, the pressure gauge can precisely show the pressure, any oil leakage occurs, pipeline is well-connected. Fix the problem once it’s recognized.
3. Check the oil quality after running the drill jumbo three months. If it’s unqualified, please first discharge all the oil and clean the oil tank before refilling it with new oil.
4. Regularly check the joints, lubrication points, exposed screw and guide rail, and filling the shaft with lubricants.
