The QHQ type double-lifting-point hoist is a commonly used equipment in water conservancy projects, primarily employed for the opening and closing of plane gates in water conservancy and hydropower projects. It features a compact structure, strong load-bearing capacity, and stable operation. Below is a detailed introduction:
Structural Features
The QHQ type hoist adopts a double-lifting-point design, equipped with an intermediate connecting shaft, enabling bidirectional opening and closing actions. Its structure includes core components such as the frame, transmission device, and hoisting system. The transmission method can be centralized drive or dual drive (for capacities above 630KN).
Applicable Scenarios
It is suitable for gate control in water conservancy facilities such as farmland irrigation, aquaculture, sewage treatment plants, reservoirs, and river dams. Particularly when the frame bridge height is sufficient and the rope deflection angle is small, it can replace arc gate hoists or hydraulic hoists, reducing equipment costs.
