The SW955K is a 5.5-ton class wheel loader engineered for high productivity in demanding applications. Meeting China Stage IV emission standards, it combines a powerful engine with a heavy-duty 6-ton planetary transmission and intelligent control systems, delivering exceptional performance, fuel efficiency, and reliability in mining, quarry, construction, and material handling operations.
SW955K Stage IV Wheel Loader
The SW955K represents a new generation of wheel loaders designed to excel in the toughest working conditions while maximizing operator comfort and efficiency. At its core is a high-performance engine that delivers reliable power while meeting stringent Stage IV emission standards .
The machine features a custom-designed heavy-duty 6-ton planetary transmission specifically developed for loaders. This transmission increases travel speed by 10% and traction force to 175kN (significantly higher than the industry standard of 155kN), resulting in over 15% improvement in comprehensive operating efficiency . The 60-series transmission paired with a 10-liter displacement engine and 6-ton heavy-duty frame significantly enhances load capacity and addresses common durability issues found in 50-series planetary transmissions .
The hydraulic system utilizes an industry-leading load-sensing quantitative triple-pump confluence design. Flow is distributed on demand, with priority given to the steering system at low RPM for responsive steering, while flow is directed to the working system at high RPM to enhance operating efficiency. The triple-pump confluence enables faster boom raising speeds (14% improvement) for quicker stockpiling and short-distance loading .
The center-hinge articulated design ensures that the front and rear wheel tracks are perfectly aligned, reducing tire wear and extending tire life while providing a smaller turning radius for better maneuverability in confined spaces .
The fully hydraulic braking system features dual independent circuits for front and rear axles, providing superior reliability, safety, and responsiveness compared to conventional air-over-hydraulic systems commonly used in the industry .
The operator cab is designed for comfort during long working hours, featuring excellent visibility, ergonomic controls, and effective climate control. Operators report reduced fatigue even after 10+ hours of continuous operation .
The machine is equipped with an intelligent management system featuring a 7-inch smart touchscreen display and EVI big data management terminal APP, enabling both on-site and remote intelligent monitoring of machine operations and faults in real-time . Features include remote monitoring and lock protection, one-click service call, intelligent fault diagnosis, and fleet networking capabilities .
