QPKY series hydraulic hoist unit for emergency plane gate service
QPKY Series Hydraulic Hoist — hoisting unit built for high-speed emergency plane gates in water conservancy and hydropower projects.

Product Summary

The QPKY Series Hydraulic Hoist is designed for the operation of high-speed emergency plane gates in water conservancy and hydropower projects. It provides a maximum holding force of 12,500 kN, with a 5,000 kN configuration also available, and a maximum design stroke of 20 m. The unit is specified for fast emergency response, high reliability, large holding force and safe shutdown capability, which makes it suitable for hydropower station emergency protection systems.

Key Selling Points

  • 12,500 kN maximum holding forceA 5,000 kN configuration is also available, so gate holding capacity can be matched to the actual head and gate load of the station.
  • 20 m maximum design strokeSupports deep gate openings and long travel requirements in dam and intake structures.
  • Fast emergency responseBuilt for high-speed emergency plane gate operation, where closing speed and response time protect the station.
  • Safe shutdown capabilityDesigned to hold and shut down safely under load, reducing risk during emergency gate closure.
  • CPMS-JD stroke sensor integrationAn independently developed absolute stroke sensor delivers millimeter-level positioning and strong resistance to electromagnetic interference.
  • Overload protection and anti-corrosion buildHeavy load design with overload protection and high anti-corrosion performance for long-term dam site operation.

Models and Options

12,500 kN configuration

Maximum holding force class for large plane gates and high-load emergency closure duty.

5,000 kN configuration

Reduced holding force class for gates with lower design load, using the same QPKY hoist platform.

Stroke and control options

Design stroke up to 20 m, with CPMS-JD stroke sensor feedback and matched control valve group and electrical control system.

Materials and Structure

The hoist is built in iron with a heavy load structure intended for continuous dam site duty. The assembly combines the hydraulic hoisting unit, cylinder and rod set, position sensing and the matched hydraulic and electrical control group. Overload protection and safe shutdown capability are part of the design, and the surface build is specified for high anti-corrosion performance in outdoor hydropower environments.

Applications

  • High-speed emergency plane gates in hydropower stations
  • Dam gate opening and closing
  • Navigation lock gate operation
  • Flood control and water level regulation
  • Power station safety operation and emergency protection systems

Case Study

EPC Contractor · Lock Gate Project · 30 Units

A complete set of hydraulic hoisting equipment was supplied to an EPC contractor for safe and efficient lock gate operation. Each hoist is integrated with the CPMS-JD absolute stroke sensor, providing millimeter-level positioning accuracy and strong resistance to electromagnetic interference, with a 30-year design life.

Hydropower Authority and Large EPC Contractor · 40 Sets

Forty hoist sets were delivered for dam gate opening and closing, flood control, water level regulation and power station safety operation. The heavy load design, high anti-corrosion performance and overload protection maintain reliable lifting under ultra-high water pressure, with a 27-year service record.

Customization

Hoists are configured per project: holding force class, design stroke up to 20 m, stroke sensor integration, and system-level supply covering the hydraulic power unit and electrical control. Project documentation is issued against the gate data provided by the buyer.
