Construction in complex terrain XCMG XR220D Rotary Drilling Rig

Power and Hydraulic System

Equipped with Cummins QSL electronically controlled turbocharged engine, with a high power of 242kW, sufficient power reserve, good fuel economy, and Euro III emissions standards; The core hydraulic components use Kawasaki components, with maximum power and positive flow control, distributing flow according to demand, saving fuel when the load changes, fast drilling response, and smooth composite action.

Single row rope main winch (core highlight of D series)

The classic single row rope structure in the industry, with a single-layer arrangement of steel wire ropes, greatly reduces extrusion wear and significantly improves the service life of steel wire ropes; Windmill integrated drilling depth detection, more accurate depth measurement; The main winch has a lifting force of 230kN, a fast lowering speed, and a higher efficiency in soil collection cycle.

Chassis and overall stability

Special hydraulic telescopic crawler chassis for rotary excavation+large diameter slewing support: the crawler extends outward in working state, making the whole machine stable and resistant to overturning; When transitioning, the track retracts without the need for extensive disassembly, making it convenient for board truck transportation. High strength box type drilling mast+parallelogram variable amplitude mechanism, strong rigidity, mast verticality can be automatically/manually adjusted, high drilling accuracy, suitable for construction of building piles, road and bridge foundation piles.

Construction adaptability

Rated torque of 220kN · m, maximum aperture of 2m, conventional drilling depth of 67m, specially equipped drill pipe up to 80m; standard winch pressurization and casing drive interface, can be matched with casing to deal with quicksand and easily collapsed formations; Optional multi section machine lock/friction drill rod, suitable for clay, sand, gravel, soft rock and other formations; The power head drive button is detachable, making maintenance and replacement simple.
