HYPAC C820C STATIC SMOOTH DRUM ROLLER

Technical Description

The Hypac C820C is a static smooth drum roller designed for efficient compaction in construction applications. It features a 41.7-inch diameter smooth drum with a nominal amplitude of 0.1 inches and a static linear load of 103.1 pounds per inch, providing strong compaction force. The drum operates at a vibration frequency of 2,040 vibrations per minute, with additional specific frequencies at 34 Hz to optimize soil consolidation. Powered by a Deutz BF4L 1011 four-cylinder diesel engine, the C820C delivers 75 horsepower at 2,650 rpm, combining power with durability. The engine benefits from a compact, air-cooled design with integrated oil cooling, ensuring reliability and ease of maintenance. The roller has a fuel capacity of 29.1 gallons and an operating weight of 11,001 pounds, enabling stable operation over diverse terrain. Its operating width is 60.8 inches, with a ground clearance of 12.4 inches and an overall length of approximately 13.8 feet. Maneuverability is enhanced by a tight turning radius of 109.5 inches and a 7.3-foot wheelbase. The C820C rolls on 340/80R18 IT530 tires, supporting transport and traction. This model runs on a 12-volt electrical system and achieves a maximum speed of 6.3 mph. The combination of heavy static load, high vibration frequency, and robust Deutz engine makes the Hypac C820C a versatile machine ideal for compacting granular and mixed soils on road construction, earthworks, and other infrastructure projects.
