Detailed description
400kN · m high torque+dedicated rock entry mode, combined with high pressure, high drilling efficiency and good pore quality in hard rock, gravel, and moderately weathered rock layers.
The maximum hole depth is 103m and the aperture is 2.8m. The whole machine is heavy, with an H-shaped telescopic chassis and double boom structure, strong anti overturning ability, and stable vertical control of deep piles.
Cummins high-power engine+load sensing hydraulic system, intelligent adjustment of three levels of power, fast action, smooth compound action, and lower fuel consumption than its peers.
The key hydraulic and electrical components are reliably configured, the structural components are reinforced and durable, suitable for continuous high-intensity construction, with low failure rate and fast cost recovery on the construction site.
The main winch is designed with a single row rope, which does not bite or mess with the rope. The steel wire rope has a longer lifespan, reduces replacement costs, and provides more accurate depth measurement.
