INGERSOLL RAND SD-77DXTF STATIC SMOOTH DRUM ROLLER

Technical Description

The Ingersoll Rand SD-77DXTF is a heavy-duty smooth drum vibratory roller designed for efficient soil compaction across various soil types. Powered by a Cummins 99 hp engine, this model offers robust performance with an operating weight around 17,700 lbs and a fuel capacity of 47 gallons. Its 66-inch wide smooth drum, with a diameter of 48 inches, delivers a vibration frequency ranging from 1,850 to 2,025 vibrations per minute (30.8 to 33.8 Hz), generating centrifugal forces between 23,380 and 32,148 lbs for high compaction efficiency. The roller features a nominal amplitude of 0.1 inches at both high and low frequencies, optimizing compaction without over-disturbing the soil. Its operating width measures 74 inches with an inside turning radius of 128 inches, facilitating maneuverability on various job sites. The hydraulic system holds 22 gallons of fluid, supporting smooth machine operation. The drum weight distribution is approximately 8,500 lbs on the drum and 7,850 lbs on the tires, balancing static load for consistent compaction. The max travel speed is about 9.1 mph, enabling efficient transportation and work pace. Overall dimensions include a height of 115 inches to the top of the ROPS/FOPS structure and a wheelbase of 105 inches, ensuring operator safety and machine stability. This compactor is engineered for durability, reliability, and ease of maintenance, suitable for contractors requiring high-performance soil compaction equipment in roadwork, site preparation, and other heavy construction applications.
