When using two or more chain hoists for drifting loads, the angle of lift should not exceed what degree with the vertical?

In rigging applications, maintaining the proper angle of lift when using multiple hoists is crucial for safety and load stability. The recommended maximum angle of lift should not exceed 30 degrees from the vertical when using two or more chain hoists.

This limit is established to ensure that the forces acting on the hoists remain balanced, helping to prevent excessive loads or uneven distribution across the hoists. When the angle exceeds 30 degrees, the risk of tipping or causing excessive strain on the equipment increases significantly, which can lead to equipment failure or accidents.

A lower angle of lift (such as 15 degrees) may provide even greater stability, but 30 degrees is the upper limit that balances operational flexibility with safety. Options that suggest angles higher than 30 degrees, like 45 degrees or 60 degrees, increase the likelihood of instability and potential accidents, making them inappropriate for safe rigging practices involving chain hoists.
