[LOW PROFILE & PORTABLE] - This mini hydraulic cylinder is ultra-thin portable, but strong in load-bearing capacity. It is particularly suitable for use in tight spaces and is characterized by its lightness and flexibility. The surface is finished with a chrome plate to protect the longevity of the product.[SPLIT DESIGN] - The split hydraulic lifting cylinder is easy to disassemble for storage. However, it must be used with a hydraulic pump, otherwise the oil pressure will not be enough to withstand normal use. The 10T/20T must be used with the CP-180 hydraulic pump. The 30T/50T/100T must be used with CP-700 hydraulic pump.[5 TYPES FOR OPTION] - This hydraulic ram has 6 specifications to choose from: Load capacity: 10T/20T/30T/50T/100T. You can choose the suitable model according to your needs.[NOTE] - After the pressure is released, the cylinder's piston cannot retract by itself! You need to push the jack to retract, which is not a quality issue. To function properly, all cylinders must be placed on a fixed lifting surface. Using cylinders on sandy, loamy or loose surfaces can result in cylinder damage.[WIDE APPLICATIONS] - This hydraulic cylinder jack can be used in power, chemical, steel, bridge, shipbuilding, machinery and other industries. However, this does NOT apply to cars!
