Fast pulling‑out speed SUNWARD SWDM220 Rotary Drilling Rig

Power and Hydraulic System

Cummins QSL9 engine, with a high power reserve of 242kW, strong adaptability to high altitude and cold weather, and excellent fuel consumption control.
Power head dual speed regulation, wide speed range of 6-26rpm, soft soil acceleration, hard layer stable torsion; Equipped with imported main pump as standard, with low pipeline loss and high overall transmission efficiency.
The maximum torque is 245kN · m, the maximum aperture is 2m, and the maximum drilling depth is 69m, which can cover the majority of municipal, housing construction, and small and medium-sized bridge pile foundations.

Chassis and overall stability

Shanhe special telescopic track chassis, with adjustable track gauge of 3-4.5 meters and 800mm wide track plates, low grounding pressure, and not easy to sink on muddy construction sites
Hidden mast auxiliary support legs, strong anti overturning ability in drilling holes; Box type foldable drilling mast with high torsional rigidity, adjustable tilt angle in front and back/left and right of the mast, and controllable verticality of the hole position.
The overall weight of the 76 ton machine is reasonable, with sufficient pressure and lifting force, and deep hole operation is not easy to shake the machine.

Mobility and transition advantages

Compact body, good site passability, obvious advantages in narrow urban construction sites and construction within enclosures
Support overall trailer transportation with drill rods, foldable drilling mast, less disassembly and quick transition, saving trailer and disassembly labor costs.

Intelligent electronic control and operation experience

Self developed intelligent electronic control system, automatic monitoring of mast verticality, real-time display of drilling depth, pressure self inspection, and automatic fault alarm.
Pilot control, smooth and precise movements, easy for beginners to get started; Standard configuration of Shanhe Cloud platform, allowing remote viewing of work hours, fuel consumption, faults, and locations on mobile phones, making it convenient for device owners to manage their devices.
Optional wireless remote control walking amplitude, improving safety in high-risk working conditions.
