Hydraulic jacks suitable for heavy lifting, mechanical removal, bridge and ship building, equipment calibrated, foundation settlement, static piling, excavation of non-hydraulic jacking machine, equipment maintenance and other operations, Jack, with special tools, Compression can be achieved, the finale and the pressure bearing assembly operations, can be used alone, it can also be used with multiple hydraulic jacking simultaneously through the shunt valve. I produced electric hydraulic jacks, with output power weight ratio, remote operation can be achieved through high-pressure hose. Fitted with a safety valve and packing equipment, pressure relief valve to prevent overload use, in order to facilitate safe operation. When the jack during the different lifting operations, electric jack, hydraulic jack speed requirements are not the same, then we need to rise to hydraulic jacks adjust the speed. (1) shall be individually speed debugging circuit (system drive and control hydraulic system of a mechanical means), whether in debugging a circuit, the rest of the loop should be turned off (barrier oil) state. (2) must also adjust the position accuracy clearances and hydraulic jacks good guide when adjusting the speed of the moving parts, separate jack, does not result in the occurrence of transmission parts tight and stuck phenomenon. If mixed with air in the jack, separate hydraulic jacks, speed is unstable, open the exhaust valve hydraulic jacks during debugging, excluding remain in the air jack. For no exhaust valve hydraulic jacks, hydraulic jacks must be moved back and forth several times while in motion unscrew the drain chamber suitable pipe joint to see the oil spill from the threaded connections tightened fittings.
