A true. Here are the four biggest reasons why you must inspect the crane: It is a legal requirement; Human safety; Liability; Machinery reliability; It is imperative you have cranes inspected by trained, qualified inspectors. If the qualified person determines that, though not presently a safety hazard, the component needs to be monitored, the employer must ensure that the component is checked in the monthly inspections. Inspection procedure for cranes in regular service is divided into two general classifications based upon the intervals at which inspection should be performed. Travel steering, brakes, and locking devices, for proper operation. Where these instructions are unavailable, the test must be conducted in accord with written load test procedures developed by a registered professional engineer familiar with the type of equipment involved. The inspection must assure that the modifications or additions have been made in accord with that approval and must include functional testing of the equipment. The load chain or wire rope is only one of the critical components.
