Outrigger retractable of hydraulic truck crane bearing

Because the bearing capacity of the Automobile Tire Co., during the lifting operation must put down the leg, make tire overhead, and the car must be the away leg. There are two legs before and after the crane bearing , each leg were controlled by the manual reversing valve, the legs with horizontal and vertical hydraulic cylinder hydraulic cylinder (mobile crane bearing ).Vertical hydraulic cylinder with bidirectional hydraulic lock, to ensure that the leg is reliably locked, prevent the lifting operations occurring in the process of Soft Legs phenomenon or in the driving process of hydraulic legs automatically falls,ferris wheel bearing .
