Steel strand jack

A steel strand jack is composed of a hydraulic oil cylinder, a lower lifting mechanism, an upper lifting mechanism and a guide mechanism, and the hydraulic oil cylinder is composed of an upper cover, a piston head, a piston rod and a lower cover. The lower lifting mechanism is composed of a pressing disc, a spring, a clamping piece, a lower taper sleeve and a guide column. The upper lifting mechanism is composed of an upper guide column, an upper pressing disc, an upper spring, an upper clamping piece, an upper taper sleeve and a tray. The guide mechanism comprises a guide pressing disc, a guide disc and a guide tray. The utility model provides a steel strand jack for lifting heavy objects in a narrow space, has a double-station synchronous lifting structure, increases the lifting force, reduces the number of jacks during construction, improves the lifting operation efficiency, and has the advantages of reasonable design, convenience in operation and stability in lifting. 钢绞线千斤顶，由液压油缸、下提升机构、上提升机构和导向机构组成，液压油缸由
