Main Technical Parameter

Description of Crawler Two Boom Drilling Jumbo DT2-35D

DT2-35D crawler two boom hydraulic drilling jumbo is specially designed for big slope. It adopts explosion proof design, can apply to the excavation drilling in the coal mine, metal mining, hydro power tunnel and other underground tunnels. The drilling speed is 0.8-2 meter per minutes.

The hydraulic parallel boom can make sure the feeding beam keep parallel fully. 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.

Telescopic can make up of displacement difference when drilling the hole of bottom and top, thus no blind angle left.

The standard configuration is equipped with imported rock drifter. It can drill hard rock with fast drilling speed and with low drilling bits consumption and low failure rate. Imported America HELAC Rotary Actuator with high torque, high bearing, fits, tight spaces, high anti-pollution, long durability.

The cable reel can save the labor and improve the safety.

Adopt drilling control system and manual four direction handle to control directly two pairs of parallel cylinder to make the boom 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.
