<p>Lifting equipment for moving a temporary installation is disclosed. The lifting equipment for moving a temporary installation includes: a plurality of hydraulic cylinders which moves a temporary installation upwards or downwards; a fluid tank which stores a fluid; at least one multi-pump which supplies a hydraulic pressure to the hydraulic cylinders at the same time; a hydraulic pipe which moves the fluid; a motor which drives the at least one multi-pump; an accumulator which stores part of the hydraulic pressure; a pressure gauge which indicates information on a state of the hydraulic pressure; a control box which controls the hydraulic pressure such that the hydraulic pressure can be uniformly supplied to the hydraulic cylinders; at least one pressure control valve which transmits a hydraulic pressure exceeding a preset hydraulic pressure to the fluid tank through the hydraulic pipe when the hydraulic pressure is greater than the preset hydraulic pressure; and an orientation control valve which controls an amount of the fluid supplied to the hydraulic cylinders, or the hydraulic pressure. Accordingly, a tuning factor can be improved by providing the multi-pump having no need of a separate hydraulic distributer and supplying the same hydraulic pressure to the hydraulic cylinders, and a construction period can be shortened and the purchase cost of the separate hydraulic distributer can be saved by eliminating purchasing the separate hydraulic distributer or connecting it to the multi-pump and the hydraulic cylinders.</p> |
