The invention provides a wide-range height-adjustable hydraulic lifting device comprising a supporting mechanism, a moving mechanism, an oil way system and a lifting height measuring device. The moving mechanism and the measuring device are both installed on the supporting mechanism. The oil way system is connected with the supporting mechanism. The supporting mechanism is a main body structure of the hydraulic lifting device and is used for installing the moving mechanism, the oil way system and the measuring device. The moving mechanism is used for transferring the lifting device, and the moving mechanism is divided into two parts which are fixed to the supporting mechanism and the oil way system correspondingly. The oil way system is used for storing and conveying hydraulic oil and installed on the supporting mechanism. The measuring device is used for visualizing the position of the lifting device, and measuring and calibrating devices of the measuring device are installed on the supporting mechanism and the oil way system correspondingly. According to the hydraulic lifting device, the movement direction of an oil cylinder can be changed through a hand-operated direction change valve, and the lifting stroke is large and can be adjusted at any time according to use conditions. Meanwhile, lifting of the device is achieved through a hand pump, no electrical requirement is needed for workplaces, and the wide-range height-adjustable hydraulic lifting device can be suitable for various workplaces.
