● The mechanical fully translation drill arm has the function of keeping the propelling beam parallel in all directions, which can be positioned directly, quickly and accurately; the drilled hole is relatively parallel to the hole, no manual alignment is required, the operation is simple, and the control is excellent. Hole-to-hole spacing accuracy and parallelism. The boom is designed with a square beam section to make the overall force of the boom more stable. The rotating motor at the front end of the boom can rotate the entire propulsion mechanism ±180° and move flexibly. The self-developed special propulsion carriage is cold-drawn as a whole and calibrated several times, and has the characteristics of bending resistance, torsional strength, compact structure and light weight. It is equipped with imported hydraulic rock drill as standard, featuring high rock drilling hardness, high drilling hardness, fast drilling speed, low drilling tool consumption and low failure rate. Adopt imported screw oil cylinder, high torque, high bearing capacity, no position offset, ultra-compact, good anti-fouling ability and durable.

● Hydraulic rock drills have better reliability and performance, and the efficiency is more than 2-4 times that of pneumatic rock drills. The imported rock drill is equipped with a hydraulic compensation system, which can prevent the air drilling under the operation error from protecting the rock drill; the special structure design of the fiber tail can eliminate the reaction force during the impact, and play the role of counter-strike protection to prolong the service life of the rock drill.

● The use of special cable reels can realize flexible and automatic cable retraction and unwinding of equipment in and out of the field, save manpower and material resources, improve safety, and have a higher degree of automation, making drilling rigs more flexible in and out of the field.

● In the excavation of mines and diversion branch tunnels, large inclination slopes have always been the bottleneck in construction. Our company has developed a large inclination crawler excavation trolley for large inclination angles, which can greatly reduce the number of workers and labor intensity.
