摘要： A suspending hydraulic pillar includes an oil cylinder, a movable prop, a handle-valve body, a reset spring, a top cover, a bottom seat, a three-way valve, a position-limiting steel wire, and a guide ring. The handle-valve body is provided between a port of the oil cylinder port and the moveable prop. Position-limiting steel wire, a guiding ring, and an oil inlet is located on a lower part of the moveable prop. The three-way valve is provided in the handle-valve body. A dust-prevention ring and a sealing ring are provided between the handle-valve body, the movable prop, and the oil cylinder. The handle-valve body is fixed on the oil cylinder by means of a connecting steel wire. The handle-valve body does not move up and down as the movable prop telescopically extends or contracts. The suspending hydraulic has good stability, high strength and supporting force, good sealing, and high anti-erosive capability.
