INGERSOLL RAND SD-77F STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand SD-77F is a high-performance smooth drum vibratory roller designed for efficient soil compaction across granular to cohesive soil types. It features a 66-inch wide, 48-inch diameter vibratory drum equipped with 84 pads, each 3 inches high, delivering a consistent nominal amplitude of 0.1 inches. The drum generates a substantial centrifugal force of approximately 29,900 pounds at both high and low settings, with vibration frequencies ranging from 1850 to 2025 vibrations per minute (vpm), enhancing compaction effectiveness. Powered by a turbocharged Cummins B4.5T Tier 2 engine, it produces 99 horsepower (74 kW), ensuring robust performance with reliable fuel efficiency. The compactor has an operating weight of 17,780 lbs and operates at a maximum speed of 9.6 mph, making it versatile for various pavement and foundation projects. Its compact dimensions include a top cab height of 9.7 feet, an overall length of 16.6 feet without the blade, a turning radius of 128 inches, and a wheelbase of 8.8 feet, facilitating maneuverability in confined spaces. The hydraulic system holds 22.2 gallons of fluid, and the fuel tank capacity is 47.1 gallons. It runs on a 12-volt operating voltage system and uses heavy-duty 14.9x24 tires with a 6-ply rating for traction. This model is engineered for durability, serviceability, operator comfort, and safety, making it suitable for diverse compaction applications in road construction and earthworks.
