STONE SW850-II STATIC SMOOTH DRUM ROLLER

Technical Description

The STONE SW850-II is a heavy-duty smooth drum roller designed for efficient soil and asphalt compaction. It features a wide 79-inch drum that delivers uniform compaction over a broad surface area and operates at a high vibration frequency range of 2,500 to 4,000 vibrations per minute (vpm), ensuring optimum ground density. The machine’s operating width is 87 inches, providing ample coverage for varied compaction tasks. Its tight turning radius of 173 inches inside enhances maneuverability on confined sites. Powering the SW850-II is a robust Deutz TCD2012L04-2V diesel engine, a turbocharged 4-cylinder inline model with water cooling. This engine has a displacement of approximately 247 cubic inches (4.04 liters) and outputs 138 horsepower at 2,400 rpm, along with a maximum torque of 384 lb-ft at 1,600 rpm. Weighing about 882 lbs, the engine balances performance and durability, ideal for sustained heavy-duty operation. The SW850-II combines reliable power and advanced vibration capability for superior compaction performance, making it suitable for road construction, asphalt paving, and soil stabilization projects requiring smooth and consistent rolling results.
