Product Introduction
SD22 is equipped with Cummins or Weichai national three-cylinder engines, air-to-air cooling + turbocharging, strong power, low fuel consumption, radial seal air intake system for longer service life. Equipped with torque converter and powershift transmission, two-stage direct transmission, high efficiency and stability.
Ergonomic design and easy operation, some models feature electronic throttle control for greater precision and convenience. A spacious, hexagonal cab with wide visibility and an optional FOPS/ROPS system ensures safety. Various types of shovels, rippers, and towing frames are available to adapt to various working conditions.
Convenient maintenance, an easy-to-open side cover, a high level of electrical system protection, and an external lubrication point enhance maintenance efficiency. The Shantui chassis is robust and durable, with a long ground path, high ground clearance, a smooth ride, and excellent off-road capability, making it capable of operating in challenging conditions.
