1. Hydraulic Drill Boom

1) High Efficiency: Unique translation design of drill boom improves accuracy and parallelism of borehole spacing, which achieves accurate and quick positioning.

2) Flexible Movement: Rotary motor in the front of upper arm makes the whole feed mechanism move flexibly (± 180°).

3) Heavy Duty Aluminium Alloy Propelling Beam & Stainless Steel Coating: High anti bending and twisting strength, and stainless steel coating all ensures long service life of full hydraulic drill jumbo DW1-31.

2. Rock Drill of Single Boom Jumbo

1) High Efficiency: Rock drill we employed is imported from France Montebert, which can be used to drill rock with high hardness. Its efficiency is two to four times of traditional handheld rock drill.

2) Long Service Life: Shank special structure is designed to eliminate reaction of the strike, which can extend service life of rock drill.

3. Hydraulic System of Wheel Drilling Jumbo

1) Multiple filtration system improves oil cleanliness and reduces failure of hydraulic system.

2) Rational pump flow and efficient water cooler ensure that the system can maintain normal oil temperature after long hours’ working.

3) Single boom drilling jumbo adopts stepwise compression technology, which optimizes the match between propelling force and impact force, and improves the positioning and drilling efficiency.

4) It is also equipped with a manual four direction control lever.

4. Chassis of Wheel Drilling Jumbo
