DYNAPAC CA302/402 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA302/402 Static Smooth Drum Roller is engineered for medium-range soil compaction tasks, particularly effective in compacting rock fill and various base and subbase courses. It features a wide smooth drum with a width of 2130 mm (83.9 in) and a drum diameter of 1543 mm (60.8 in), ensuring substantial ground contact for uniform compaction. The roller operates at a vibration frequency of 33 Hz with a nominal amplitude of 0.1 in in both high and low modes, producing centrifugal forces of 67,443 lb (high) and 32,822 lb (low), facilitating deep and consistent density achievement. Powered by a 125 hp engine, the machine weighs approximately 27,999 lb, providing a static linear load conducive to effective soil densification. Its overall dimensions are 18.21 ft in length, 6.99 ft in width, and a cab height of 9.76 ft, with a wheelbase of 9.45 ft and ground clearance of 15.75 in, granting good maneuverability and stability. The fuel capacity is 66.1 gallons, enabling extended operational periods with a maximum speed of 5.6 mph. The Dynapac CA302/402's design includes options for cab configurations and accessories like compaction meters and computers, enhancing precision and operator comfort. Its robust construction and advanced vibration system make it suitable for a wide range of compaction applications in road construction, infrastructure projects, and earthworks requiring reliable smooth drum compaction performance.
