Hydraulic telescopic crane is a kind of crane which realizes lifting, luffing, telescoping and 330°/360°swinging by hydraulic system driving, mainly composed of slewing support device, luffing cylinder, telescoping cylinder, hydraulic motor, reducer and control device. When working, the hydraulic motor drives the slewing support device to make the crane get on board part of the crane to slew smoothly, and the control device can adjust the speed and direction; the piston of the luffing cylinder is pushed by the hydraulic pressure to realize the back-and-forth and up-and-down movement of the boom; and the piston rod of the telescopic cylinder is driven by the hydraulic pressure to realize the back-and-forth movement of the boom. With flexible operation and good stability, this crane is widely used in automobile cranes, marine cranes and other equipment. We offer a variety of models such as 2T and others to meet the lifting needs of different scenes.
