The QPG type single lifting point hoist is specialized equipment for hydropower and water conservancy projects, primarily used to control the opening and closing of plane gates. Below are its core specifications:
Core Parameters
?Rated Hoisting Capacity?: Ranging from 160kN to 12500kN, covering 9 grades (e.g., 160kN, 250kN, etc.). ?
Lifting Height Range?: From 30m to 160m, with 9 standard values (30m, 40m, 50m, etc.). ?
Hoisting Speed?: The average linear speed of a single rope is between 1.6m/min and 6.3m/min, inversely related to the load grade. ?
Structure and Performance
?Key Components?: Drum group diameter tolerance controlled within ±1%, gear pair machining accuracy meeting the 8-8-7 grade standard, wire rope adopting the 6W(19) type structure with a safety factor ≥4.5. ?
Safety Devices?: Equipped with a height indicator (accuracy ≤±5cm), mechanical limit switches, and a load controller.
