Large-scale hoist-type gate hoists are specialized hydraulic equipment designed for operating large-span gates. Their core function is to rapidly close the gates to protect the unit or pipeline, typically achieving gate closure within 2 minutes. ?
Structural Composition
Primarily consists of an electric motor, coupling, brake, drum, and pulley system, connected to the gate via steel cables or pulley groups to enable lifting and lowering control. ?
Key Functions
?Rapid Gate Closure?: In the event of an incident, it can automatically trigger a DC power supply to quickly close the gate, with the descent speed limited to within 5 meters per minute to prevent collision between the bottom edge and the sill. ?
Dual Operating Systems?: Equipped with local operation (AC power) and remote operation (DC power), ensuring reliable performance under both normal and emergency conditions. ?
Safety Protection?: Features a normally closed brake that can be manually released to control gate closure, along with anti-collision speed-limiting devices.
