High‑efficiency soil unloading SUNWARD SWDM160 Rotary Drilling Rig

ower and Drilling Performance

The power head delivers a torque of 160kN·m with a maximum rotating speed of 42rpm for high slag removal efficiency. It can work in clay, sand, pebble layers and moderately weathered rock. Equipped with a high-pressure common rail engine, it features sufficient power reserve, good fuel consumption control and smooth power response. The main winch provides strong pulling force with one-click soil shaking function to shorten time for lifting and discharging soil. It supports a maximum pile diameter of 1.5m and maximum drilling depth of 52m with two-section drill mast, covering most medium and small foundation pile projects.

Stable Structure and High Durability

It adopts self-developed heavy-duty telescopic crawler chassis with 360-degree rotation for construction and stable center of gravity. Built-in outriggers balance stability and maintenance space for chassis. High-strength box mast and square shaft box force structure resist torsion and deformation, suitable for long-hour continuous operation. Single-layer rope arrangement of the main winch greatly reduces wear of steel wire rope, extending its service life by around 50% and lowering consumable replacement cost.

Flexible Transfer and Easy Transportation

The total machine weight is about 48 tons. As a lightweight medium model, it can be transported together with drill rods without dismantling mast and drill rods. It saves assembly and disassembly time, showing obvious advantages for short-distance transfer between multiple construction sites, ideal for rental business with frequent site changes.
