QP Single-Point Gate Winch Hoist for Reliable Operation
Product Introduction
The QP series single-point winch hoist is a hydraulic engineering machine designed for the opening and closing of plane gates in water conservancy and hydropower projects. Key models include QP1×50, QP1×80, QP1×100, QP1×125, QP1×160, QP1×250, QP1×400, QP1×630, QP1×800, QP1×1000, QP1×1250, and QP1×1600. Featuring a single-point winch configuration, it offers a simple structure, low cost, and easy maintenance.
The QP series single-point hoist is capable of operating plane sliding gates, plane fixed-roller gates, and concrete gates. When the gantry bridge height is sufficient and the rope deflection angle is minimal, it can replace radial gate winches and hydraulic hoists for radial gate operation, reducing equipment investment. Equipped with an electric dual-purpose operating mechanism, it is suitable for water conservancy, hydropower, flood control, drainage, sluice gate, and pumping station applications.

Product Features
Simple Structure, Low Cost: The single-point winch design uses only one drum and one lifting point, resulting in a compact structure and lower manufacturing costs. Ideal for plane gates with relatively narrow widths.
Wide Applicability: Capable of operating plane sliding gates, plane fixed-roller gates, and concrete gates. Under suitable conditions, it can replace radial gate winches and hydraulic hoists for radial gate operation.
Dual Manual/Electric Operation, Safe & Reliable: The electric dual-purpose operating mechanism ensures normal electric operation, with manual operation available during power outages or malfunctions. The brake engages automatically upon power failure, ensuring reliable gate positioning.
Complete Range of Models and Specifications: Available from QP1×50 (approx. 50KN) to QP1×1600 (approx. 1600KN), meeting the requirements of various water conservancy projects.

Working Principle
The QP series single-point winch hoist operates on the principle of a winch combined with wire rope and a single lifting point. The motor drives the gearbox to rotate the drum, and the wire rope wound around the drum connects to the gate lifting point via a pulley block, enabling the gate to be raised or lowered.
During the lifting operation, the motor rotates forward to wind the wire rope and raise the gate. During the lowering operation, the motor reverses to release the rope, allowing the gate to descend and close under its own dead weight. The brake holds the gate securely in any position. The manual operating mechanism drives the gearbox input shaft via a hand crank or handwheel, enabling manual operation when no power supply is available.
Structural Composition
The hoist consists of the following core components:
Frame and Base: A welded steel frame that supports all transmission components and withstands the hoisting forces. Secured to the pier with anchor bolts.
Winch Mechanism: A single drum wound with wire rope, connected to the gate lifting point via a pulley block. The drum diameter and rope capacity are designed based on the hoisting force.
Deceleration Transmission System: Motor-gearbox-drum configuration, where the gearbox reduces speed and increases torque.
Brake: Shoe brake or hydraulic thrust brake, which engages automatically upon power failure to ensure reliable gate positioning.
Electrical Control System: 380V three-phase power supply with a control cabinet for hoisting operations, limit protection, and overload protection.

FAQ
Q: What is the primary application of the QP series hoist?
The QP series winch-type single-point hoist is primarily used for opening and closing plane gates in hydraulic and hydroelectric projects. It can operate plane sliding gates, plane fixed-wheel gates, and concrete gates.
Q: What is the difference between single-point and double-point hoists?
A single-point hoist uses one drum and one lifting point, offering a simpler structure and lower cost, making it suitable for narrower gates. A double-point hoist uses two drums connected by a synchronous shaft, providing more even load distribution on the gate, making it suitable for wider gates.
Q: What is the difference between the QP and QPK series?
The QP is a standard winch-type hoist without speed control. The QPK adds a speed control device to the QP, enabling rapid emergency gate closing. Both series share the same external dimensions and mounting dimensions for the same specification.
Q: Does the hoist require regular maintenance?
Yes. Key maintenance tasks include: monthly inspection of wire rope wear and lubrication; quarterly inspection of brake clearance; semi-annual inspection of reducer lubrication; and an annual overload test at 1.1 times the rated load.
Q: Can custom (non-standard) configurations be ordered?
Yes. The QP series hoist can be custom-configured, including hoisting capacity adjustment, lift height changes, and special anti-corrosion requirements. Please provide parameters such as gate weight, dimensions, and installation conditions.
