Quick Hoist Gate Operators are specialized closure devices designed for the operation of quick gates. Quick gates are used to protect machinery units or steel pipes, hanging above the opening during normal operation. In the event of an accident with the generator, pump, or steel pipe, they can quickly cut off the water flow to preventAccidentExpand. The closing time of the quick gate should meet the protection requirements for the equipment and steel pipes, generally requiring the opening and closing machine to close the quick gate within 2 minutes. Additionally, to prevent damage to the bottom edge and bottom sill of the gate due to violent collisions, the quick hoist opening and closing machine should be equipped with a speed-limiting device, restricting the descent speed to 5m/min or less when the gate approaches the bottom sill. However, there are no speed restrictions during the descent process, as long as it does not cause damage to the components of the opening and closing machine.
