Crane and rigging teams must never exceed the load capacity of a mobile crane. Load size and weight should be calculated, and load moment indicators can be used to prevent accidental overloads. All rigging equipment, including slings, chains and hooks, etc., must be inspected daily, and any rigging equipment showing damage must be immediately removed from service. Loads should be properly secured and moved over the approved pick plan. All boom movements should proceed smoothly, with no sudden stops or accelerations.
Prior to positioning a mobile crane, rigging teams should survey the area for electrical lines and other obstacles, and measures should be taken to maintain required clearances during rigging procedures. Soft, unlevel, or unstable ground can cause a crane to tip over, so outriggers should be used when necessary; crane should never be operated if the wheels lift off the ground.
When a crane is moving, the boom should be held in the direction of movement to maintain stability. Empty hooks should be lashed or secured to prevent swing. If there is a possibility of the boom falling backward, boomstops should be used. Mobile crane operators should sound an audible warning to warn riggers of pending movement, and rigging personnel should stay clear of the load, crane wheels, and outrigger wheels. A signal person should direct crane movement if the operator has a limited view.
