HYPAC C850D STATIC SMOOTH DRUM ROLLER

Technical Description

The HYPAC C850D is a static smooth drum roller designed for high‑efficiency soil and asphalt compaction in road construction and site preparation. It features a large-diameter steel drum with a diameter of 59.1 in (150 cm) and a width of 83.9 in (214 cm), providing broad coverage and uniform static linear load of 178.1 lb/in for consistent compaction results. The roller operates with two vibration frequencies—30 vpm and 36 vpm—enabling adaptability to different material types and density requirements, while the nominal medium amplitude of 0.1 in ensures effective surface consolidation without excessive impact. Power is delivered by a 4‑cylinder TCD2013L042V diesel engine producing 133 hp (99 kW) at 2,200 rpm, offering reliable performance and fuel efficiency. With an operating weight of 26,590 lb and a static configuration, the C850D is optimized for applications where controlled, non‑impact rolling is required. It has a top travel speed of 6.3 mph (10 km/h) and a fuel tank capacity of 66.1 gal, supporting extended operation between refueling. The machine’s compact dimensions include a ground clearance of 19.3 in, overall length of 19.2 ft, wheelbase of 9.8 ft, and a cab height of 9.8 ft, allowing good maneuverability on job sites. It is equipped with 23.1‑26/12PR tires and a 12‑volt electrical system, making it a robust, straightforward compaction solution for medium‑to‑heavy duty applications.
