Audited Supplier 1. The HF25(K) down the hole drill rig for open use is an improved device in compliance with national regulations on diesel engine emissions. Equipped with the Yuchai four-cylinder engine (China III), the drill rig meets national standards for emissions and environment.
2. The folding frame track and four-wheel drive are adopted, and track leveling and the walking motor of plunger piston improve the working pressure and climbing capacity.
3. The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position.
4. The rotary torque and revolving speed are raised. The propulsion motor and chain are used to raise the lifting force and reliability.
5. The thickened profile folder is used for the housing, thus improving its level of intensity and rigidity, and the additional ring makes handling and lifting convenient.
Tips
1. The enlarged dust collector can be equipped to produce a better effect on dust collection, thus making operation more environment-friendly and reliable.
2. Air compressor selection subject to hole diameter and air hose length.
