Principles and Applications of hydraulic lifts: Rail cargo lifter for lifting goods hydraulic lifting machinery and equipment, the use of hydraulic cylinders as the main driving force, through the heavy chain and wire rope drive to ensure the absolute safety of the machine is running. Without room, especially suitable for basement, warehouse transformation, new shelves, etc., with easy installation and maintenance, beautiful, safe, and convenient operation. According to the actual site specific production environment. ● The maximum load 10 tons, multi-point control, interactive interlocking top and bottom floors, reaching the safe use; ● high lifting height, using sunk cylinder or double cylinder test type, run smoothly, no noise, easy maintenance, long service life ; ● manual power down the emergency stop button, convenient, fast and practical; ● pit depth is generally 15cm-30cm, height unrestricted top-level, can be customized according to the site environment with; ● layer through the doors, inside and outside the plant can poke each other open, convenient, space-saving; ● particularly suitable for 2-3 layer steel plant, can be used inside and outside; ● cylinders and seals using imported parts, resolve customer hydraulic unstable parts leakage problems.
