Description

The YX620 2-ton wheel loader is engineered for optimal performance in various operational environments. It features a load-sensing hydraulic steering system that allows for easy and flexible operation, ensuring reliability and comfort for the operator. The articulated frame design, with a significant steering angle and small turning radius, is ideal for navigating narrow spaces. The mechanical linkage hydraulic control system minimizes driver fatigue, enhancing productivity during extended use.

Powered by a high-performance engine and a single-stage three-element hydraulic torque converter, the YX620 maximizes engine power utilization. Its fixed shaft power shift transmission increases torque, resulting in superior traction force. Safety is prioritized with a high-tensile unitary frame structured cab, while the ergonomically designed indoor cab layout offers ample operating space. The shock absorption system further enhances user comfort, making it an excellent choice for demanding tasks.

With reinforced drive axles for greater load-bearing capacity and long service life, the YX620 ensures stability and efficiency. Its optimized hydraulic system shortens cycle times, boosting loading efficiency. Additionally, the power transmission system is designed to enhance fuel economy, with average working speeds exceeding those of competing models.
