How to choose the Class of Duty for an EOT Crane?
Selecting the appropriate class of duty for an EOT (Electric Overhead Traveling) crane is crucial to ensure its longevity, safety, and efficiency. This classification system categorizes cranes based on their usage intensity and load spectrum.
Here are the key factors to consider when choosing the class of duty:
1. Load Spectrum:
- Maximum Load: The heaviest load the crane will lift.
- Average Load: The typical load weight during regular operations.
- Load Frequency: How often the maximum and average loads are lifted.
2. Duty Cycle:
- Operating Hours per Day: The number of hours the crane will be in operation daily.
- Number of Lifts per Hour: The frequency of lifting operations.
- Hoist Travel Distance: The distance the hoist travels during each lift.
- Trolley Travel Distance: The distance the trolley travels during each lift.
- Bridge Travel Distance: The distance the bridge travels during each lift.
3. Environmental Conditions:
- Temperature: Extreme temperatures can affect the performance and lifespan of the crane’s components.
- Humidity: High humidity can accelerate corrosion and reduce the lifespan of electrical components.
- Dust and Debris: Exposure to dust and debris can lead to premature wear and tear on mechanical components.
4. Special Requirements:
- Shock Loads: If the crane will be subjected to frequent shock loads, a higher duty class may be necessary.
- Frequent Starts and Stops: Frequent starts and stops can increase wear and tear on the motor and gearbox.
- Precise Positioning: If precise positioning is required, a higher duty class with more accurate controls may be needed.
5. Common Class of Duty Classifications:
While specific classifications may vary between manufacturers, common classes include:
- Light Duty: Suitable for infrequent use with light loads.
- Medium Duty: Suitable for moderate use with moderate loads.
- Heavy Duty: Suitable for frequent use with heavy loads.
- Severe Duty: Suitable for continuous use with heavy loads and harsh environments.
