This series of heavy-duty automatic down the hole (DTH) surface blast hole drill rigs developed and manufactured by Zhejiang ZEGA Machinery Co., Ltd. with diesel engine, air compressor and automated hydraulic control system on board is standard equipped with cabin, automatic drill pipe handling system, heavy-duty tramming motor and chassis with oscillation mechanism. The smooth drilling system, fast tramming speed and cross terrain adaptability make this series of rigs suitable for many complicated rock drilling applications. These rigs equipped with two stage dust collector is environmental friendly and widely used in various construction and mining applications. High efficiency, energy saving, environment friendly and many safety features also make these drill rigs highly recommended for green mining and global market.
The Main Features: The drill rig is designed for drilling large, medium and deep holes and for complicated rock conditions.
High Efficiency
Reduced drilling preparation time due to high efficient automatic drill pipe handling system up to 6 m long drill pipe and strong cross terrain capability. The penetration rate is highly improved with less rock drilling tools consuming because of the high pressure and large displacement screw air compressors on board for more complete debris flushing. The larger diameter drill pipes contribute to less compressed air consumption when flushing. Powerful feeding and rotation design reduces jamming problems on top of enhances drilling speed even with complicated rock bases. Single operator lower labor cost. Bigger hole sizes require less number of total holes.High performance drill rigs reduce the fleet size.
Energy Saving
Single power pack (only one diesel engine) drives both screw air compressor and hydraulic system with power output of stagger design. Comparing with separated drills, the power output of diesel engine of the automatic DTH rig is reduced by 30% and maintenance cost reduced by 50%. Lower total energy consumption, faster drilling speed, shorter preparation time and less holes reduce the drilling cost per capita sharply.
Environmental awareness
Standard two stage (optional water mist system) dust collector makes this series of rigs very much environment friendly.
Safety
The track oscillation system makes the rig center of gravity more stable while climbing up and down the slopes giving the tracks superior traction. Less equipment and workers are required. The drill pipe carousol and cab protect operation personnel from accident.
Product Features of the drill rig
1.Caterpillar, Steyr and Yuchai engines with global WARRANTY to meet various demands.
2.Parts labels is marked at the two ends of pipes and electricity wires and also highlight in the parts manual for easier maintenance.
3.Feeding & lifting system:State of the art cylinder and steel wire rope design meets various feeding and lifting torque requirement. Less wear and tear parts for easier maintenance.
4.Feed beam & boom:Heavy duty box design feed beam, arm, bracket and boom resists and absorbs sudden force impact.
5.Tramming system:Compact chassis with heavy-duty speed reduction mechanism possesses good cross terrain capability. Track oscillation function gives both tracks maximum ground grasping. ±10 degree track oscillation makes machine more stable when climbing up and down slopes.
6.Maintenance:Modular centralized design offers easier access to ①daily maintenance, ②diesel engine maintenance, ③system adjustment, ④dust collector maintenance via each independent swing side doors with bigger maintenance and service room for convenience.
