Crawler Mounted Rotary Blast Hole Drill Rig - High Torque High Axial Pressure Mining Drilling Equipment for Open Pit Quarry

Product Description

Product Description                                                        

Product introduction

Efficient and Stable
 1. It features high axial pressure, large torque, high rotational speed, large-diameter
     perforation and high production efficiency.
 2. The combined pressurization mechanism consisting of hydraulic cylinders, wire ropes
     and chains enables stable and reliable pressurization and lifting, with precise control
     over the axial pressure.
 3. Selecting engines and air compressors from international first-tier brands to ensure
     the stable and reliable performance of the whole machine.

Energy-saving and Environmental Protection
 1. There are options for diesel-powered or electric-powered drive systems. Depending
     on the actual mining process of the mine, high-pressure or low-pressure air
     compressor systems can be selected. It is highly efficient, energy-saving and has
     low production costs.
 2. Dry dust removal is equipped as standard, and wet dust removal is available as an
     option, which is environmentally friendly.

Widely Applications
 1. It has two operation modes, roller rotation and down-the-hole impact, demonstrat-
     ing good adaptability to working conditions and a wide range of applicable rock
     formations.
 2. Enhanced track roller, carrier roller, idler and tracklink assembly, large-torque
     travel motor and three-point floating leveling chassis, with good adaptability to
     terrains.
 3. The main frame platform has a box-type structure. The main beam is made of
     high-strength structural steel formed by rectangular cold drawing, incorporating the
     design concept of stress dispersion, which is stable, durable and reliable.

Safe and Comfortable
 1. The FOPS-certified operator's cab meets international safety standards.
 2. The operator's cab is equipped with double-layer insulating glass, which can
     block noise and heat, offers a broad view and creates a comfortable
     operating environment.
