The dual-purpose flashlight hoist is a gate control device that integrates electric and manual functions, primarily used for gate lifting and lowering management in water conservancy, municipal, and other fields, combining safety and flexibility.
Core Functions
Dual-mode operation: It can be remotely controlled via an electric device or manually operated by cranking in emergencies, ensuring manual intervention during power outages or equipment failures.
Safety protection: Equipped with built-in torque protection and travel limit devices, it automatically stops operation once the gate reaches its position, preventing overload damage to the equipment.
Status display: Features a pointer-type opening indicator for intuitive display of the gate's open/close position; heating resistors automatically remove internal moisture to ensure the reliability of electrical components.
Models and Parameters
Common models include the QDA series (single suspension type) and QDS series (double suspension type), such as QDA-20 and QDS-2×10, catering to different tonnage requirements (3T—100T). When ordering, environmental requirements (indoor/outdoor/explosion-proof), lifting height, and suspension point spacing must be specified.
Applicable Scenarios
Suitable for water conservancy irrigation, urban water supply, sewage treatment, and other scenarios, it offers anti-water theft functionality and supports multiple control methods (on-site/remote, single/centralized control), adaptable to special environmental needs such as standard, outdoor, and explosion-proof types.
