Winch-type mobile hoist

The winch-type mobile hoist is a mechanical device used in hydraulic engineering to control the opening and closing of gates. It drives the lifting and lowering of gates via steel wire ropes or chains and features mobility to adapt to different operational scenarios.
Structure and Function
The winch-type mobile hoist primarily consists of components such as an electric motor, coupling, brake, drum, and pulley block. It achieves gate lifting and lowering through transmission by steel wire ropes or chains. Its mobile mechanism can travel along tracks, supporting unidirectional or bidirectional movement (e.g., lateral movement along the dam face or upstream/downstream travel). It is available in two forms: trolley-type and gantry structure.
Applications
Widely used in reservoirs, river management, hydropower stations, and environmental protection projects, it supports flood control scheduling and water resource allocation. For example, in emergency closure scenarios involving rapid gates, this equipment can complete gate closure within 2 minutes and is equipped with speed limit devices to prevent violent impacts.
Technical Parameters
Lifting Capacity: 6-125 tons
Movement Type: Trolley-type or gantry structure
Drive Type: Primarily electric drive, with optional manual crank device
Installation Requirements: Requires embedded foundation bolts and concrete pouring. Commissioning involves no-load and rated load tests.
