QP Type Double-Point Gate Winch Hoist
Product Introduction
The QP series double-drum double-lifting-point winch hoist is a type of hydraulic engineering machinery used for the lifting and lowering of plane gates in water conservancy and hydropower projects. Key models include QP2×50, QP2×80, QP2×100, QP2×125, QP2×160, QP2×250, QP2×400, QP2×630, QP2×800, QP2×1000, QP2×1250, and QP2×1600. It features a double-drum synchronized winch structure, ensuring even force distribution on both sides of the gate for smooth and reliable operation.
The QP series double-drum hoist is capable of operating plane sliding gates, plane fixed-wheel gates, and concrete gates. When the machine bridge height is sufficient and the rope deflection angle is small, it can replace radial gate winches and hydraulic hoists for operating radial gates, thereby reducing equipment investment. Equipped with a manual/electric dual-purpose operating mechanism, it operates electrically under normal conditions and can be switched to manual operation during power outages or malfunctions. It is suitable for projects in water conservancy, hydropower, flood control, drainage, and sluice pump stations.

Product Features
Synchronized Dual-Point Drive for Smooth Operation: The dual-point design ensures even force distribution on both sides of the gate, preventing tilting during lifting and lowering. A synchronous shaft connects the two winch mechanisms, guaranteeing consistent vertical movement of both lifting points.
Wide Applicability: Capable of operating plane sliding gates, plane fixed-wheel gates, and concrete gates. Under suitable conditions, it can substitute for radial gate winches and hydraulic hoists for radial gate operation, reducing equipment investment.
Manual/Electric Dual-Purpose, Safe and Reliable: Features a manual/electric dual-purpose operating mechanism. Operates electrically under normal conditions and manually during power outages or malfunctions. The brake engages automatically upon power failure, ensuring the gate stops reliably.
Complete Range of Models and Specifications: Available in various specifications from QP2×50 (approx. 100KN) to QP2×1600 (approx. 3200KN), meeting the needs of water conservancy projects of different scales.

Working Principle
The QP series double-drum winch hoist operates on the structural principle of a winch combined with wire ropes and dual lifting points. The motor drives the gearbox, which rotates the drum. The wire rope wound around the drum connects to the gate lifting points via a pulley block, enabling the gate's lifting and lowering motion. The two lifting points are connected by a synchronous shaft, ensuring the wire ropes on both sides reel in and out simultaneously, allowing the gate to move smoothly without tilting.
To lift the gate, the motor rotates forward to wind the wire rope. To lower it, the motor reverses to unwind the rope, allowing the gate to descend and close under its own Dead Weight. The brake can hold the gate securely at any position. The manual operating mechanism drives the gearbox Input Shaft via a hand crank or handwheel, enabling manual operation in the absence of Power Supply.
Structural Composition
Comprises the following core components:
Frame and Base: A welded steel frame structure that supports all transmission components and bears the lifting force. Secured to the pier or machine bridge with Anchor Bolts.
Winch Mechanism: Each of the two drums is connected to one lifting point, with Wire Rope wound around them. The drum diameter and rope capacity are designed based on the required lifting force.
Deceleration Transmission System: Consists of motor, Gearbox, synchronous shaft, and double drums. The gearbox reduces speed and increases torque. The synchronous shaft ensures both drums rotate at the same Rotational speed.
Brake: Utilizes a Shoe brake or Hydraulic Thrust Brake, which engages automatically upon power failure to ensure the gate stops reliably at any position.
Electrical Control System:380V three-phase power supply, with a Control Cabinet for Lifting/Lowering operations, limit protection, and Overload Protection. Optional Manual/Electric switching and remote control available.

FAQ
Q: What is the primary application of the QP series hoist?
A: The QP series winch-type double lifting point hoist is primarily used for operating plane gates in hydropower and water conservancy projects. It can handle plane sliding gates, plane fixed-wheel gates, and concrete gates. When site conditions permit, it can also serve as an alternative to radial gate winches and hydraulic hoists for operating radial gates.
Q: What is the difference between the QP and QPK series hoists?
A: The QP is a standard winch-type hoist without a speed governor, suitable for gate operation under normal conditions. The QPK incorporates a speed governor on top of the QP design, enabling rapid emergency gate closure for projects requiring emergency shutdown capabilities. Both series share identical external dimensions and installation footprints for the same specification.
Q: What is the difference between a double lifting point and a single lifting point hoist?
A: The double lifting point hoist connects both winch mechanisms via a synchronous shaft, allowing both lifting points to act simultaneously on both sides of the gate. This ensures the gate lifts and lowers without tilting or binding, making it ideal for wide plane gates. Single lifting point hoists are suited for smaller, narrower gates.
Q: Does the hoist require regular maintenance? What are the key maintenance items?
A: Yes. Key maintenance items include: ① Monthly inspection of Wire Rope wear and Lubrication; ② Quarterly inspection of Brake clearance and Braking torque; ③ Semi-annual inspection of Gearbox/Reducer Lubricating Oil level and quality; ④ Annual overload test at 1.1 times the rated load; ⑤ Inspection of Anchor Bolts and machine frame Weld Seams for loosening or cracking.
Q: Can the QP hoist be custom-built to non-standard specifications?
A: Yes. The QP series hoist can be custom-built to meet specific project requirements, including adjustments to hoisting capacity, Lift Height, Lifting Point Center Distance, and special Anti-corrosion requirements. Custom orders require parameters such as gate weight, dimensions, and on-site installation conditions.
