Technical Description

The Hyundai HR120C-9 is a static smooth drum roller designed for efficient soil and base compaction in construction and infrastructure projects. It features a 26,455.5 lb (12,000 kg) operating weight and a wide 82.7 in (2,100 mm) smooth drum with a 59.1 in (1,500 mm) diameter, providing consistent ground contact and high compaction performance. The roller delivers a high centrifugal force of 53,954.2 lbs and low centrifugal force of 31,473.3 lbs, with two vibration frequencies of 40 vpm and 140 vpm, and a nominal amplitude of 0.1 in in both high and low settings for versatile compaction across various materials. Power is supplied by a Deutz TCD 2012 L4 diesel engine, delivering 130 hp (97 kW) of gross power for reliable, fuel-efficient operation. The machine has an overall length of 226.7 in, width of 7.5 ft, and a wheelbase of 125.8 in, with 19.3 in of ground clearance for good obstacle negotiation. It is equipped with 23.1-26 tires and reaches a maximum speed of 7.8 mph (11 km/h). Fuel capacity is 79.3 gal and hydraulic system fluid capacity is 28.1 gal, supporting extended work cycles with reduced downtime for refueling and servicing.
