Hoist-type trolley hoist

The winch-type gantry hoist is a mechanical device that combines the features of gantry hoists and winch hoists. It is primarily used in hydraulic structures for multi-hole shared gates or gate systems that require mobile storage. Its core structure includes:
Structural Features
‌Mobile Carrier‌: Designed with a gantry system, equipped with a unidirectional load-moving trolley, offering flexibility for multiple gate openings or temporary gate storage scenarios. ‌
Transmission Method‌: Utilizes a winch mechanism to raise and lower the gate, where the drive mechanism rotates the drum, using wire rope winding and unwinding to control gate movement. ‌
Function and Application
‌Applicable Scenarios‌: Suitable for trash racks or maintenance gates with a hoisting capacity of ≤100kN or 2×100kN, meeting special requirements for multi-hole sharing or gate storage outside the opening. ‌
Safety Design‌: Must include a maintenance platform to ensure routine upkeep and troubleshooting. ‌
Technical Parameters
‌Hoisting Capacity‌: Typically ≤100kN or 2×100kN, with some models capable of up to 4000kN (e.g., hydraulic steel dam gates). ‌
Operating Speed‌: No speed limit for normal operation; speed is limited to 5m/min during rapid closure to reduce impact damage.
