Overhead cranes with more than one hoisting unit must have what marked on them?

Overhead cranes equipped with more than one hoisting unit must have the rated load clearly marked on them to ensure safe operation. The rated load indicates the maximum weight that the crane can safely lift with each hoisting unit working together. This is critical for preventing overloading, which can lead to equipment failure, accidents, or injuries.

Marking the rated load provides operators with essential information to make informed decisions about the loads they are maneuvering, especially when multiple hoisting units are involved. It ensures all personnel are aware of the lifting capacity and reinforces adherence to safety regulations and practices. This labeling is vital not just for compliance but also for protecting the equipment and ensuring the safety of all workers on site.
