ZGYX-440 / 450 / 460 / 470
Product Introduction
This series of heavy-duty automatic down the hole (£)TH)'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 rigs
highly recommended for green mining and global market.
The Main Features
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
lowers 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.
Made of special steel, stated of the art structure and manufacture design and process.
