This is a WZ40-28 backhoe loader, with an operating weight of 6.5 tons and transport dimensions of 7600×2200×3100mm, balancing operational flexibility and ease of relocation. It integrates loading and digging functions: the loading end is equipped with a 1.5m³ bucket, a digging force of 38KN, a loading lifting capacity of 2800KG, and a bucket unloading height of 3600mm, enabling efficient material loading and transfer; the digging end is equipped with a 0.3m³ bucket, with a maximum digging depth of 4000mm (optional telescopic boom extends the depth to 5000-5500mm), a bucket rotation angle of 180°, and a traction force of 39KN, making it suitable for scenarios such as foundation pit excavation and small-scale earthmoving operations.
The power system features a turbocharged engine (multiple models available) with a rated power of 85KW, matched with a single-stage three-phase torque converter and power-shift gearbox. Combined with four-wheel drive and a single-stage wheel-side reduction gear structure, it maintains stable power output even on muddy and rugged terrain. The steering system supports a steering angle of ±40° and a minimum turning radius of 4600mm, offering good operational flexibility. The system pressure is 12Mpa, ensuring the efficiency of each actuator. Overall, this equipment is a multi-functional work tool for small and medium-sized projects, municipal maintenance, and agricultural infrastructure, achieving the efficiency of "one machine replacing multiple machines."
