Large winch-type hoist

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.
