The Sunward SWDM85S is a compact, multi-functional hydraulic rotary drilling rig engineered for foundation piling in confined, restricted-access, and urban jobsites. Combining agility with high-torque rotary performance, the SWDM85S delivers the power required for deep-foundation drilling while maintaining a compact footprint that simplifies transport and setup. Core Features & Engineering HighlightsDual Drilling Flexibility (LDP & CFA): Designed to switch rapidly between Large Diameter Piling (LDP / Kelly bar) and Continuous Flight Auger (CFA) modes. This quick-conversion architecture allows contractors to handle varied ground conditions and structural specs with a single machine. Reliable Powertrain: Powered by a turbocharged Cummins F3.8 / QSF3.8 diesel engine rated at 90 kW (120 HP). It meets EU Stage V and EPA Tier 4 Final emission standards, combining low fuel consumption, quiet operation, and extended service intervals to keep total cost of ownership (TCO) down. High-Torque Rotary Drive: Delivers a maximum torque of 80 kN·m (approx. 58,920 lbf·ft) across a variable speed range of 8 to 35 rpm. This provides aggressive penetration through hard soil layers and medium-strength rock formations. Jobsite Agility & Fast Setup: Features a tight swing radius for easy positioning against existing structures and inside confined boundaries. Single-button automated mast raising and lowering speeds up cycle times during site setup and teardown. Hassle-Free Transport: Built with a transport width of 2,500 mm (approx. 8.2 ft) and an operating weight around 25,000–28,000 kg (55,000–61,700 lbs). The rig can be hauled on standard flatbed trailers without requiring special wide-load road permits. Heavy-Duty Hydraulics & Winch: Utilizes premium hydraulic components paired with high-line-speed main winches for responsive hoisting, controlled penetration, and reduced wear on wire ropes. Ergonomic, Safe Operator Cab: Equipped with a certified ROPS/FOPS pressurized cabin, high-visibility glass, vibration dampening, and a real-time digital drilling monitor displaying mast verticality, drilling depth, and rotary torque load.Technical SpecificationsParameterMetricImperialOperating Weight~25,000 – 28,000 kg~55,000 – 61,700 lbsEngine Make & ModelCummins QSF3.8 / F3.8Cummins QSF3.8 / F3.8Rated Engine Power90 kW @ 2,200 rpm120 HP @ 2,200 rpmEmission StandardsEU Stage V / US EPA Tier 4FEU Stage V / US EPA Tier 4FMax.
