JK hydraulic lifting device

JK type hydraulic lifting equipment mainly consists of top beam, down beam, upper and lower slip, oil cylinder, base and measurement and control console etc. Measurement and control console consists of manual directional valve, diversion collector valve, relief valve, pressure gauge, guide valve, the barometer, pressure sensor, PLC, LCD and so on. When equipment installs in place, start power source and air compressors and operate gas control manual valve of slips. operate a hydraulic manual directional control valves to the rising position and promote top beam lifting upward through upper slip stuck drill pipe. After lifting to a requested level, firstly dominate gas control handles of slip to make the next slip clamp drill pipes. Then operate slip gas control handle to make slip in loosen state. Operate a hydraulic reversing valve handle to drop location. Pressure oil pours into upper cavities of two oil cylinders to drive top beam downward and return. The above process is a work cycle. After several continuous working cycles, it can reach the purpose of jam release.
