W235-8 crawler type hydraulic excavator uses originally imported Yanmar engine, net power 25.2KW, EU EC (NRMM) STAGE ¢̣ and EPA Tier ¢̣ emission standards. The global service network of Yanmar engine can meet global customers' needs for after-sales maintenance and repair.
Key components of the hydraulic system, such as main pump, main valve, rotary motor and travel motor are all originally imported products. W235-8 has superior performance: boom, arm and bucket circuits all have confluence systems, which improves work speed and efficiency. Meanwhile, the travel system also has excellent performance, the high travel speed is 4.7km/h and the low travel speed is 3.0km/h, featuring industry-leading travel speed amongst the counterpart products. This working device can be deflected and can work under demanding conditions. It can not only work along the wall but can dig two parallel ditches at a time. It is also equipped with pipelines for crushing operation as standard configuration.
New appearance design and rhombus platform. The edges use golden section ratio method, which not only has the visual beauty, but also has strong rigidity. Meanwhile it also greatly increases the stability of the machine during work.
The humanization design makes the operator's work more comfortable. Handles and switches are all located within the operator's reach, which enables the operator to move in the smallest scope and maximally reduces operator fatigue. With ergonomically designed handles, it greatly reduces operator fatigue even if in successive long time operations. Though it is a small capacity machine, it is mounted with air conditioning system as standard configuration, providing a comfortable operator environment.
