The invention relates to a working method of an intelligent hydraulic construction hoist, and belongs to the field of construction hoists. The hydraulic system comprises a lift car, an oil cylinder and car body connecting piece, a hydraulic oil cylinder, a variable-frequency hydraulic oil pump motor, a hydraulic main pump, a hydraulic pipe and a hydraulic oil tank. The amplitude of an operating handle of the construction hoist is transmitted to the frequency converter, the frequency converter outputs different frequencies to the speed-adjustable hydraulic oil pump motor according to changes of input signals to adjust the speed, the operating handle transmits the signals to the frequency converter according to the proportion of 0-100, and the frequency converter transmits the signals to the variable-frequency hydraulic oil pump motor according to the proportion of 0-50 HZ to control the speed of the variable-frequency hydraulic oil pump motor. The device is simple and reasonable in structural design, safe, reliable, convenient to operate, stable and efficient in work and low in noise, and meets the use requirements.
