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.
