Underground Drilling Jumbo

Underground drilling Jumbo

An underground drilling  rig jumbo is a mechanical device used in underground mines or tunnel construction, mainly used for rock drilling and drilling. It is usually equipped with an efficient drill bit and a powerful hydraulic system, which can crush rocks and drill holes in a small space. It is suitable for mining, tunnel construction and other projects. 

Underground single boom drilling jumbo

FK20-1BCDL is a single boom electro-hydraulic drilling jumbo for fast and accurate drilling for small-vein underground mining and tunneling and construction applications. The jumbo is suitable for tunnel with coverage area max. up 6.0-meter x 6.1 meters with 15°grade ability at maximum load on four drive wheels. Drilling hole diameter range from 32mm to 76mm. The drill boom can rotate 360 degrees and is equipped with automatic anti-jamming function. It has a compact structure, stable performance and strong climbing ability. It is suitable for drilling operations on working faces, roofs, side panels and bottom plates with a section of 8-45m². Not only it can drill blast holes, but also drill bolts very conveniently. The Jumbo is equipped with new model Focor550 hydraulic rock drill, the impact frequency is 50-68Hz higher than other similar brand.

Twin-boom Hydraulic Face Drilling Jumbo

FK20-2BCDL hydraulic face drilling jumbo is designed for underground mining, tunneling, and construction applications. It is suitable for medium- to large tunnel with coverage area max. up to 8.7 meters x 6.3 meters. Drilling hole diameter ranges from 32mm to 76mm, hole depth ranges from 2.1 to 3.5 meters. The jumbo is equipped with a patent-winning Focor 550 Hydraulic rock drill with 24KW impact power.The electric motor provides power for the operation. The hydraulic system controls the drilling process, and the the diesel engine provides the power for the moving and slope climbing of the jumbo. Safe and efficient hydraulic-driven system applies to the entire machine. Separate hydraulic pumps controls anti- jamming, feeding, and rotary of the drilling process. All the alarm indicators, such as the overheat indicators for water and oil temperature, guarantee the miners to know the real conditions of the jumbo all the time.
The jumbo can be used not only for drilling blast holes, but also can drill drift rods. The rock drill guarantees accurate precision and maximum drilling speed. For the miners, the jumbo provides maximum safety protection, better working efficiency and lower expenses on the drilling rods.
