主要用于自卸车（翻斗车）的液压举升系统，为货箱举升油缸提供高压液压油，驱动货箱完成举升、倾斜卸料动作，是自卸车液压系统的动力源核心部件。
- 采用铝合金泵体 + 高强度铸铁端盖，集成了控制阀 / 溢流阀组件，具备体积紧凑、耐磨损、抗冲击的特性，专为重卡恶劣工况设计。
It is mainly used in the hydraulic lifting system of dump trucks (tipper trucks), supplying high-pressure hydraulic oil to the lifting cylinder of the cargo box, driving the cargo box to complete lifting and tilting unloading actions. It is the core power component of the dump truck’s hydraulic system.
It adopts an aluminum alloy pump body + high-strength cast iron end cover, with integrated control valve/relief valve components. Featuring compact size, wear resistance, and impact resistance, it is specifically designed for the harsh working conditions of heavy-duty trucks.
