For overhead cranes with more than one hoisting unit, which feature is required?

• A. Its own daily inspection log on each hoist.
• B. Its rated load marked on it.
• C. A wind-indicating device.
• D. Automatic rail clamps.

Answer: (B)

Knowing the maximum weight the crane can safely lift is essential when more than one hoisting unit is in use. Having the rated load marked on the hoist(s) makes that capacity clear to the operator. It provides a clear limit for single-hoist operations and for any combination of hoists, helping you plan lifts without exceeding the crane’s structural and mechanical limits. This visibility prevents overload, which could lead to damage or collapse, and it supports proper rigging and coordination when multiple hoists are involved. Daily inspection logs are important for ongoing maintenance, but the requirement that directly supports safe multi-hoist operation is the presence of a clearly marked rated load. Wind-indicating devices and automatic rail clamps aren’t universally required specifically because there are multiple hoists.
