JK590BC-2A Split Crawler Type Open-Pit Hydraulic DTH Drilling Rig

Jinke JK590BC-2A Split Crawler Type Open-pit Hydraulic DTH Drill Rig

The JK590BC new generation split-type open-pit hydraulic DTH drill rig is used for drilling and rock drilling in open-pit mining operations such as cement, metallurgy, coal mines, and quarries, as well as in engineering construction for railways, highways, water conservancy, hydropower, and national defense projects. Its hole diameter range is 90~178mm. It can be equipped with various models of air compressors to achieve high-pressure DTH drilling. During drilling operations, only the DTH hammer consumes compressed air. Compared to fully pneumatic drill rigs, the required air compressor displacement is reduced by 30%–50%. Energy consumption (fuel or electricity) during drilling operations is reduced by approximately 40%-50%.

The JK590BC is a new generation model of the JK590 equipped with an environmentally friendly hydraulic dust removal system. If water is available on site, a wet dust removal system can also be selected.

Large rotation torque; the new planetary gearbox is more compact than spur gear reducers, with a larger reduction ratio and higher torque transmission efficiency, ensuring smoother operation. It does not require additional components such as shock-absorbing joints for vibration reduction, resulting in lower failure rates, reduced daily maintenance costs, less jamming in loose layers, and higher hole formation rates.

Imported rotary seals with good sealing performance and long service life.

Polymer liner plates, wear-resistant and requiring no oil lubrication, making operation more convenient.

Manganese steel machined guide rails, ensuring a sturdy frame and wear-free guide rails.

Imported hydraulic oil pump, high pressure resistance, large displacement, more reliable quality, and long service life.

Yuchai 70-meter turbocharged engine (Cummins optional), powerful and easy to maintain.

Two-stage air filtration system ensures the engine吸入 clean air, safe and reliable.

Integrated oil-water radiator ensures normal operation of the engine and hydraulic system in high-temperature environments.

Imported travel motor with strong climbing ability, capable of towing an air compressor.

Dual-speed travel system, fast travel saves relocation time.

Crawler frame floats 15°, equipped with a travel balance system, suitable for rough terrain construction.

Reinforced engineering machinery crawler tracks and box-structure crawler frame, sturdy and durable.

Maintenance-free carrier rollers, no need for oil injection.

Can be equipped with a non-powered unlocking travel motor.

The JKC series hydraulic dry dust collector is specifically designed for the Jinke series open-pit DTH drill rigs. It effectively extends the service life of the drill rig, ensures the health of operators, reduces dust pollution, and offers excellent environmental protection.

The JKC series dust collector is a new type of pulse dust collector with high dust collection efficiency, large air handling capacity, stable performance, easy operation, effective dust cleaning, long filter cartridge life, and minimal maintenance requirements.
