Cooling tower maintenance often requires lifting motors, gearboxes and fan components from restricted elevated locations.
SWIN Industries designs portable davit arms and winch systems for lifting fan motors, gearboxes, drive components and maintenance equipment at industrial cooling towers.
The equipment can be customised around the tower structure, available walkway, required boom outreach, lifting height and the weight of the component being handled.
Portable davit arms can be moved between prepared base points or supplied with a suitable portable arrangement where the structure and access permit.
Electric winches are suitable for frequent lifting and can be configured for the required rope length, speed, brake and controls.
Manual hand winches can be used for occasional maintenance and controlled operation where lower speed is acceptable.
Base plates, sockets, brackets and boom reach can be developed around the cooling-tower structure and maintenance path.
Cooling tower structures may have limited access and non-standard load paths. The supporting structure and proposed base arrangement must be reviewed before equipment installation.
A site layout showing the lifting point, component location and available support structure is required to develop a practical davit arrangement.
The davit arm, base and supporting structure must be checked for the complete lifted load and overturning moment. Personnel must remain clear of suspended loads during maintenance operations.
