HAMM HD 90K STATIC SMOOTH DRUM ROLLER

Technical Description

The HAMM HD 90K is a high-performance smooth drum roller designed for efficient asphalt compaction. It features a robust DEUTZ 4-cylinder engine delivering 134.2 hp at 2300 rpm, compliant with EPA Tier 3 emissions standards. The roller’s smooth, non-divided drum measures 47.3 inches in diameter and 66 inches in operating width, with a thickness of 0.7 inches, enabling strong compaction capabilities supported by a centrifugal force of 13,488.6 lbs. Its vibration system operates at frequencies between 2,520 to 3,000 vibrations per minute, with nominal amplitude at high frequency of 0.1 inches, ensuring optimal soil and asphalt density. The HD 90K has a ground clearance of 31.2 inches and an overall width of approximately 6 feet, with a wheelbase of 133.9 inches and steering angle of 10 degrees for maneuverability. Weighing up to 24,780 lbs in operation, the model incorporates a 237.8-gallon water spray tank critical for drum surface cooling and preventing asphalt cling. Transportation speed reaches up to 9.2 mph, while working speed is about 4.6 mph. The rear is equipped with four 11.00-20 tires, providing stability and traction. The machine includes operator comforts such as a cab with a height of 10.1 feet and meets rigorous durability and operational efficiency demands for medium to large-scale road construction projects. This combination of power, vibration technology, and structural design ensures high compaction quality and productivity in various construction environments.
