505002 YS Bidirectional Hydraulic Lock

Purpose and characteristics 

The YS Bidirectional Hydraulic Lock Series is used in the hydraulic systems of truck crane, overhead working truck, piling machinery and so on. When the outrigger is laid down, the hydraulic lock can prevent automatic retraction of the hydraulic hitch legs due to oil leakage; in case of such accidents as oil tube rupture, it may prevent any accident to hydraulic hitch leg failure; while the truck crane or overhead working truck travels or parks, it may prevent sliding of hydraulic hitch legs due to its dead weight. It may be also used in other hydraulic machinery. There are two connection types available, i.e. plate and line-mounted types.
