Detailed description
With a torque of 400 kN · m and a lifting force of 400 kN, the rock penetration ability is top-notch in the industry, making it easy to conquer extremely hard formations such as weathered rocks and granite.
Intelligent switching between three levels of power head standard/rock entry/high-speed soil throwing, with strong adaptability to geological conditions.
The maximum drilling depth is 109 meters and the maximum aperture is 3 meters, perfectly suitable for national level major projects such as cross sea bridges, super high-rise buildings, offshore wind power, and deepwater docks.
Heavy duty H-type telescopic chassis+super large slewing bearing, unparalleled stability, high verticality accuracy for ultra deep hole construction.
Main winch with a speed of 60 m/min for fast lifting and high-speed soil throwing, with a hole forming efficiency 20% higher than other models of the same level.
Hydraulic system load sensing+negative flow control, fast response, precise control, low fuel consumption.
Standard centralized lubrication system, long maintenance cycle, low failure rate.
