Home » Products » Drilling Jumbo » DW1-31 Wheel Drilling Jumbo

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 is Sweden brand, WOSERLD, 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

1) Hinge jointed heavy duty Chassis, hydrostatic drive, and four wheel drive guarantee excellent power performance and fuel economy of this full hydraulic drill jumbo.

2) Key components (such as engine, drive axle, etc.) are all imported from famous supplier.

3) It has extendable and flexible front hydraulic supporting leg.

4) There are three braking conditions including running braking, parking braking and emergency braking.

5) Silencer and purifier are available to deal with tail gas.

6) Solid tyre is of filling type.

7) Driving seat is fixed.

5. Standard Configuration of Wheel Drilling Jumbo

1) Robust Housing (It can bear strong impact force of falling objects).

2) Large Power Lamp.

3) Cable Reel.

4) Air Compressor.

5) Water Pump.

6) Level Instrument.
