The QPT-type gantry winch hoist is a gate operating device used in water conservancy and hydropower projects, characterized by its mobile structure, primarily applied in scenarios requiring synchronous control of multi-hole gates. Below are its core features and functions:
Core Structure
Composed of an electric motor, coupling, reducer, drum, pulley system, and frame, it employs a three-stage reduction method to enhance load capacity and is equipped with an AC brake to ensure precise gate positioning.
Function and Application
Multi-hole Synchronous Control: Suitable for controlling multiple gates with one machine without the need for simultaneous opening, such as in large gate clusters in water conservancy and hydropower projects.
Mobile Design: The frame is equipped with a pulley device, allowing vertical, horizontal, or inclined pulling of gates to adapt to various installation environments.
Safety Protection: Equipped with automatic leakage protection and travel control (error ≤0.5%) to ensure operational safety and accuracy.
Maintenance Points
Long-term storage requires draining cooling water, replacing engine oil, and applying anti-rust treatment; monthly short-distance operation is necessary to keep components lubricated.
During operation, ensure the lifting distance matches the design of the transmission shaft support; for large lifting distances, a three-body configuration should be used to enhance stability.
