QPKY series hydraulic hoist mainly apply to opening and closing of the common plane rapid gate in hydropower project, the basic parameters and the shape of installation size is exactly the same as QPKY Ⅱseries, except the hydraulic control valve using speed control one.

Hydraulic cylinder is the hydraulic energy into mechanical energy, reciprocating motion to do (or swing movement) of the hydraulic actuators. It is simple, reliable. Use it to achieve reciprocating movement can be removed from deceleration devices, and no transmission gap, smooth motion, so in a variety of machines are widely used in hydraulic systems. Hydraulic cylinder output force and the effective area of the piston is proportional to the pressure difference on both sides; hydraulic cylinder is basically a cylinder and cylinder head, piston and piston rod, seals, cushioning device and the exhaust composition.
Buffer device and the exhaust depending on the specific application of the occasion, other devices are indispensable.
