CRANE WHEEL ASSEMBLY
An HOT (Hand Operated Overhead Traveling) crane is similar to an EOT crane but is operated manually. These cranes are ideal for lighter loads and situations where power supply may be limited or not available.
An HOT (Hand Operated Overhead Traveling) crane is similar to an EOT crane but is operated manually. These cranes are ideal for lighter loads and situations where power supply may be limited or not available. Here’s a detailed overview:
Components of an HOT Crane
- Bridge: The main structure that spans the width of the building. It consists of a single or double girder that moves along a runway.
- Runway: The tracks on which the bridge travels, typically fixed to the building's structure.
- Hoist: The device that actually lifts the load, which moves horizontally along the bridge.
- Trolley: The mechanism that carries the hoist across the bridge.
- Manual Controls: Typically involves a series of pulleys and chains for manual operation.
Types of HOT Cranes
- Single Girder HOT Crane: Features a single bridge girder supported on two end trucks. The hoist is underhung and moves on the lower flange of the girder.
- Double Girder HOT Crane: Has two bridge girders supported on two end trucks. The hoist runs on a rail installed on top of the bridge girders.
Advantages
- Cost-Effective: Generally less expensive to install and maintain compared to electric cranes.
- No Power Required: Ideal for locations without reliable power supply.
- Simple Operation: Easy to use with minimal training required.
Applications
- Workshops: Useful for small to medium-sized workshops for moving parts and tools.
- Warehouses: Suitable for handling lighter loads in storage areas.
- Maintenance Areas: Can be used for lifting and positioning equipment during maintenance.
Maintenance
Maintenance of an HOT crane involves:
- Routine Inspections: Regularly checking the condition of all components, especially the manual mechanisms.
- Lubrication: Ensuring all moving parts and chains are well-lubricated to avoid rust and wear.
- Repairs and Replacements: Promptly addressing any wear and tear or damaged parts to ensure safe operation.
Safety Tips
- Load Limits: Never exceed the crane’s rated load capacity.
- Proper Training: Ensure operators are trained in the safe use of the crane.
- Regular Inspections: Conduct regular inspections to identify and fix potential issues.
