Face Drilling Rig

Zhongrun is the solution partner of reputable domestic and international companies for tunnelling, underground mining and infrastructure projects with its comprehensive product range consisting crawler loaders, drill jumbos, mining jumbo, LHD Scooptram, undergroud truck, locomotive, hand hammer drill, scaling jumbo, rock breaker and so on.

Drilling jumbo, also called face drilling rig, as the main manufacturer of face drilling rig in China, we launches reloaded face drilling rig, face drilling rigs are used for blast hole drilling in underground mining and tunneling. So our underground drill rigs are widely applied in mining, metallurgy, water and electricity, railway, highway engineering, and other industries. Our face drilling rig can be used in small as well as big tunnel section.

Features of Face Drilling Rig:

1. Hydraulic Drill Boom of Face Drilling Rig

Double boom mining jumbo drill is equipped with special hydraulic drill boom.

1) High Efficiency: Drill boom of the underground drill rig is improved in location accuracy and speed, which

greatly increases working efficiency.

2) 360º Punching Range: Telescopic boom compensates displacement difference generated by drill arm when moving downward.

3) Stable Force: The square cross-section beam design of upper arm makes overall force on drill boom more stable.

4) Flexible Movement: Rotary motor in the front of upper arm makes the whole feed mechanism move flexibly (± 180°).

2. Rock Drill of Face Drilling Rig

1) High Efficiency: Rock drill we employed is imported from France Montabert SAS. It can be used to drill rock whose maximum hardness reaches up to 15. Its efficiency is two to four times of traditional handheld rock drill. Imported rock drill has hydraulic compensation system, which can prevent failed hit caused by operation errors.

2) Long Service Life: Special shank structure is designed to eliminate reaction of the strike, which can extend service life of underground drill rig.

3. Hydraulic System of Face Drilling Rig
1) The oil tank is located over the oil pump. Unlike the traditional tunnel drilling jumbo, oil pump of the drilling equipment is free of cavitation erosion caused by oil lack.

2) Multiple filtration system improves oil cleanliness and reduces failure of hydraulic system.

3) Rational pump flow and efficient water cooler ensure that the system can maintain normal oil temperature after long hours' working.

4. Standard Configuration of Face Drilling Rig

1) Large Power Work Light.

2) Hydraulic Air Compressor.

3) Liftable and Lowerable Safety Ceiling (Conforming with FOPS Requirement).

5. Optional Configuration of Face Drilling Rig

1) Hydraulic Water Pump.

2) Large/Small Power Diesel Engine.
