Description of Rail Mounted Drilling Jumbo DR1-14

DR1-14 rail type hydraulic drilling jumbo is mainly used for tunnel of mining and metallurgy and tunneling project of culvert. The drilling speed is 0.8-2 meter per minutes. The design of whole machine is strong. The machine is small and with compact structure, low center of gravity. The traveling type is rail, which is very suitable for small tunnel section with rail system.

Improve the quality of smooth blasting. Our company design it ourselves and get a patent for mechanical translation boom which makes the propulsion beam keep balance in all direction. It can locate the hole position directly, quickly and accurately. All the holes are parallel, no need people to correct. It is easy to operate and can improve the quality of blasting.

The oil tank is at high position. It can keep cleanliness of oil and reduce the risk of hydraulic system failure.

The hinge joint of machine breaks through the traditional design idea that the rail wheel, machine and chassis are whole, which reduce the turning radius greatly. Two hydraulic motor connects the rail wheel directly, and control and drive the rail wheel to realize responsive control.

Adopts rotary reducer and spiral swing cylinder to form cross steering joint, so there is no blind angle in any angles of the tunnel face, top, side and bottom of the tunnel section.

It is equipped with Chinese brand drifter. It is economical and can drill hole fast. Imported America HELAC Rotary Actuator with high torque, high bearing, fits, tight spaces, high anti-pollution, long durability.

Adopt drilling control system and manual four direction handle to control the boom to move translation. It is equipped with anti jamming function and gradually pressure boost system, which makes it work more stably, reduce the drilling bits consumption.

The design of whole machine is strong. The machine is small and with compact structure, Low center of gravity, flexible, single power, low energy consumption, low noise, which can improve working environment and improve construction efficiency and quality.
