Parameters of DFJ-1W31 Wheel Jumbo Drill:
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. 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.
