ZOOMLION YZD20A STATIC SMOOTH DRUM ROLLER

Technical Description

The Zoomlion YZD20A is a robust static smooth drum roller designed for efficient soil compaction in construction projects. It features a front drum with a diameter of 61.5 inches and a width of 84.7 inches, providing a broad contact surface for effective compaction. The drum delivers substantial centrifugal forces ranging between 53,954 lbs (high) and 80,931 lbs (low) alongside a nominal amplitude of 0.1 inches, with vibration frequencies of 29 and 33 vibrations per minute to optimize compaction performance. Its static linear load is rated at 247.1 pounds per inch, ensuring consistent ground pressure. Powered by a 6BTA5.9 engine producing 177.1 hp at 2200 rpm, the YZD20A can reach a maximum speed of 4.5 mph, suitable for controlled, steady compaction operations. The machine’s operating voltage is 24 volts, and it weighs approximately 44,092.5 lbs, contributing to its effectiveness in compacting soil layers. Dimensionally, it stands 10.5 feet tall to the top of the cab, spans 7.9 feet in width, and has an overall length of 19.5 feet. The roller is equipped with durable 20.5-25 tires tailored for construction site mobility and stability. These features combine to make the Zoomlion YZD20A an efficient, powerful, and reliable smooth drum roller for large-scale compaction tasks in roadwork, foundation, and other civil engineering applications.
