Overhead Crane Practice Test

What is the primary reason for leaving wraps on the hoist drum?

1. Prevents overload

2. Ensures load control

3. Enhances rope longevity

4. Reduces hook wear

The correct answer is: Ensures load control

Leaving wraps on the hoist drum is crucial for ensuring load control. When multiple wraps of rope remain on the drum, it helps maintain a secure connection between the load and the crane, reducing the risk of slippage or unintended disengagement. This is particularly important during lifting operations, as it allows the operator to have better control over the load being moved. Moreover, having wraps on the hoist drum provides additional friction, which assists in stabilizing the load. This stability is essential for preventing the load from swinging or drifting, especially in operations where precision is necessary. While other factors like rope longevity may also be indirectly influenced by the number of wraps, the primary focus remains on maintaining effective load control during operations, making this the most relevant aspect regarding safety and operational efficiency.
