The series of heavy-duty DTH surface blast hole drill rigs are developed and manufactured by Zhejiang ZEGA Machinery Co., Ltd. with diesel engine, air compressor and automated hydraulic control system on board. They are standardly equipped with cabin, automatic drill pipe changer, heavy-duty tramming motor and chassis with leveling mechanism. The smooth drilling system, fast moving and good cross terrain capability make them suitable for any complicated rock drilling applications. The rigs equipped with two stages dust collector are environmental friendly and are widely used in various construction and mining applications. High efficiency, energy saving, environment friendly and safety make it suitable to global market.
The main features:Drilling large, medium and deep holes, suitable for complicated rock conditions
High efficiency
Reduced drilling auxiliary time thanks to high efficient automatic drill pipe changer 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. The big diameter drill pipes contribute to less compressed air for flushing. Powerful feeding and rotation unit design reduces jamming problems and enhances drilling speed. Single person operation design lowers labor cost. High performed drill rigs reduce the fleet size.
Energy Saving
Single power pack drives screw air compressor and hydraulic system simultaneously and power output is stagger design. Comparing with separated drills, the power output of automatic DTH rig is reduced by 30% and maintenance cost reduced by 50%. Lower total energy consumption, faster drilling speed, shorter auxiliary time and less drilling holes reduce the drilling cost per ton sharply.
Environment-friendly
Standard two stage dry type (optional wet type) dust collector make the rigs environment friendly.
Safety
The track leveling device makes the rig center of gravity more stable to climb up and down the slopes, makes the trackline adhesion superior , The mine can employ less equipment and personnel because of its' powerful drilling capability, their drill pipe storage and cabin protection design put an end for personnel accident.
