VOLVO SD77DX STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo SD77DX is a static smooth drum roller designed for soil compaction in road construction and related applications. It features a 66-inch-wide smooth drum with a diameter of 48 inches, providing a compacting operating width of 74 inches. The roller operates with vibration frequencies of 20.4 Hz and 33.8 Hz, delivering centrifugal forces of 23,380.2 lb (low) and 32,147.7 lb (high), respectively, to optimize compaction efficiency. The nominal amplitude of vibration is 0.1 inches for both high and low settings. The machine's overall dimensions include a length of 16.55 feet, width of 5.5 feet, height to the top of the cab at 9.59 feet, and a wheelbase measuring 8.79 feet. It operates at a maximum speed of 9.1 mph, powered by a 99-horsepower engine. The operating weight is 16,350 pounds, ensuring substantial ground contact for effective compaction. Fuel capacity is 47.1 gallons, complemented by a hydraulic system fluid capacity of 22.2 gallons. The design emphasizes durability and reliability for efficient performance in diverse terrain conditions. Overall, the Volvo SD77DX combines robust power, steady vibration control, and a smooth drum width suitable for producing uniform compaction across soil and aggregate surfaces. This makes it a versatile choice for contractors requiring consistent soil stabilizing performance on various construction sites.
