Description of DT1-14 Single Boom Jumbo:

Single boom jumbo, also called single boom underground drilling jumbo, is mainly applied in tunneling construction of mining, metallurgy, water and electricity, railway, highway engineering, etc. It can work on surface of the tunnel, roof, side and floor. The single boom jumbo can not only drill the blast hole, but also drill the bolt hole easily.

1. Hydraulic Drill Boom of Single Boom Jumbo

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

2) 360º Punching Range: Telescopic boom compensates displacement difference generated by drill arm when moving downward.

3) Stable Force: The square cross-section beam design of upper arm makes overall force on drill boom more stable.

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

2. Rock Drill of Single Boom Jumbo

1) High Efficiency: Rock drill we employed is imported from France Montebert. It can be used to drill rock with high hardness, whose efficiency is two to four times of traditional handheld rock drill. Imported rock drill has hydraulic compensation system, which can prevent failed hit caused by operation errors.

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

3. Hydraulic System of Single Boom Jumbo

1) Oil Tank above Pump Motor: Oil tank is placed on the top and pump motor is erected over the bottom, which solves the defects of traditional jumbo "tank located in low position and pump located in high position". This design avoids oil pump cavitation caused by failed suction of oil pump.

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

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

4) 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.

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

4. Standard Configuration of Single Boom Jumbo

1) Large Power Work Light.

2) Hydraulic Air Compressor.

3) Liftable and Lowerable Safety Ceiling (Conforming with FOPS Requirement).

5. Optional Configuration

1) Hydraulic Water Pump.

2) Large/Small Power Diesel Engine.
