A7 Craw type open hole drill
A7 Craw type open hole drill
Applicable pore size range: 89-140mm The A7 is a split open open hole drill widely used in mines and quarries across the country. The drill is simple in structure, convenient in maintenance, strong in mobility, insensitive to rock cracks, especially suitable for generous and deep hole drilling Hole quarrying operation. Its unique high-speed hydraulic motor-driven fan dust removal system is comparable to an fully hydraulic tracked rig, lifting the operator out of dust, At the same time, it effectively slows down the wear of the drilling rig working mechanism.
The bidirectional control panel is ergonomically designed, with reasonable layout and convenient operation. The operator can control the drilling operation horizontally or vertically from any propulsion position, with a broad vision. The joystick and instrumentation facilitate direct control of propulsion and drive, the side control panel has a cantilever positioning lever, rig The rear control panel allows the operator to operate while the rig is moving.
The propulsion beam is equipped with a rotating canoner, which effectively reduces the wear of the hose in the process of rotary movement and extends the service life of the hose.
The propulsion beam in the form of oil cylinder chain propulsion, combined with the pulley positioning mechanism and the anti-wear sliding mechanism, improves the stability of the drilling and the service life of the propulsion beam.

The strong crawler walking system easily deals with high-speed displacement and rugged surface environments. With a safe walking amplitude change control platform, convenient for safe walking operation and Transposition at long distances.
With engine oil pressure, cooling temperature, engine fault alarm, battery charging indicator light, emergency stop switch and reversing warning and other safety devices.
The drilling arm structure has a wide range of activities to meet the maximum requirements of various drilling angles.
