Cranes are inspected regularly as a safety measure to ensure that all components of the crane are operating properly. Cranes are inspected for cracks, corrosion and wear. If a crane is operated under faulty components, the likelihood of those components failing increases dramatically. Faulty crane components can easily cause an accident resulting in worker injury.
Certification for operating and inspecting a crane is only achieved after an individual has undergone the battery of training and testing provided by the OSHA. To obtain certification, a person must take courses in proper crane operation and safety in crane operation and must pass a test at the end of training.
The goal of training and certifying people on proper crane operations is safety. Online Lawyer Source states that around 50 deaths occur each year from crane-related accidents.
