What are considered safety devices according to the OSHA crane standard?

Safety devices according to the OSHA crane standard are intended to protect both operators and workers in the vicinity of cranes, ensuring safe operation under various conditions. The selected choice includes devices crucial for maintaining safe crane operations.

Crane level indicators help ensure the crane is set up on a stable base, which is vital for preventing tipping during operation. Boom stops and jib stops serve to limit the range of motion of the boom or jib, preventing overextension that could lead to accidents. A horn serves as an audible alert to notify those around the crane of its movements, adding another layer of safety by helping to prevent accidents.

Each of these components fulfills specific roles in increasing operational safety and helping to avoid hazards associated with crane operations.
