The invention discloses a safe and stable hydraulic elevator which comprises a working table, a strut support, a hydraulic cylinder, a bottom box, a hydraulic pump, an energy accumulator, an engine, acontrol valve and an infrared thermometer. A U-shaped transverse beam is connected to the middle of the shearing fork type strut support, a U-shaped rib plate is paved on the U-shaped transverse beam, the hydraulic pump, the infrared thermometer and the energy accumulator are fixed to the U-shaped rib plate through short pin shafts, and the energy accumulator and the infrared thermometer are connected with alarm apparatuses arranged on the working table for monitoring and controlling the temperature of the hydraulic cylinder and a fuel tank. The safe and stable hydraulic elevator is suitablefor outdoor operation of plants, factories, workshops, ship navigation maintenance and the like, the shearing fork type small wheel elevator is adopted, the mass is small, the appearance is beautiful,the structure is compact, the temperature can be controlled, and high-temperature reminding can be achieved.
