QPQ Type Winch Hoist

The QPQ type hoist-type gate hoist is primarily used in water conservancy and hydropower projects for opening and closing flat gates, featuring smooth water flow, minimal vibration, and convenient installation and maintenance. Its design balances versatility and safety, complying with the industry standard issued by the National Energy Administration (Standard No. NB/T 10500-2021), and is suitable for hoist-type gate hoists with a head range of 6 meters to 30 meters. ‌
Structure and Function
It employs an electric drive method, equipped with a brake to ensure safe braking during power outages. The hoist support forms include two-point and three-point types, operable manually or electrically, and features a double lifting point design to enhance stability. The double lifting point structure operates synchronously via connecting rods, making it suitable for large gates. ‌
Application Scenarios
Mainly used in hydropower stations, reservoirs, flood discharge, and debris removal in water conservancy projects, it enables rapid gate opening and closing, water regulation, and maintenance functions. Typical technical parameters include a hoisting capacity of up to 6000 kN and a maximum travel of 120 meters, suitable for high-head and large-tonnage scenarios. ‌
Features
‌Synchronization‌: Double lifting point design ensures synchronous operation and balanced force distribution.
‌Stability‌: Utilizes two motors for synchronous drive, meeting the demands of large gates.
‌Safety‌: Equipped with manual/electric dual systems, allowing manual operation during power outages.
