Truck Crane hydraulic system contamination

At present, some advanced industrial countries, the company survey showed that 70% of hydraulic mechanical failure from the hydraulic system, hydraulic system so ugly that at least 75% is due to dirty hydraulic oil caused. Domestic crane hydraulic system contamination due to failures and accidents also extremely common.
  At present, some advanced industrial countries, the company survey showed that 70% of Hand stacker mechanical failure from the hydraulic system, hydraulic system so ugly that at least 75% is due to dirty hydraulic oil caused. Domestic crane hydraulic system contamination due to failures and accidents also extremely common. Such as hydraulic truck crane hoisting mechanism of the variable motor oil due to blockage of the particulate matter control ports and hinder variables, and even failure; larger than hydraulic truck crane slewing mechanism because of the oil particles clogging unidirectional rotary damping valve can not be executed instruction; pumps, cylinders, motors, locks, valves, Electric pallet truck failure due to wear particles. These are caused by the crane hydraulic system contamination, and not unjustly quality hydraulic and hydraulic components and repair underwater.
     Hydraulic crane hydraulic system is a core component. Crane operation outrigger cylinder and cylinder luffing all want to support the whole weight and load. Slewing jib crane telescopic and institutions such as motivation to work also depends on the hydraulic system. Oil pollution levels and cleanliness of the hydraulic system, the use of a direct impact on the reliability and service life of the crane
