Question

lifting equipment: cranes
a crane is a mechanical device that is used to lift, lower and move materials. in automotive shops a crane is often used to remove and install engines and transmissions.
chains, slings and cables are usually used together with the crane, to secure different types of loads.
because of the heavy weight it can carry, you must receive training before you use such equipment and always use in accordance with instructions found in the operator manual. when moving material, pay close attention to your surroundings and make sure there’s no obstacles on your path. warn people nearby that you are passing through.
warning: never attempt to lift a load that exceeds the crane’s capacity! carefully evaluate the center - of - gravity of the crane with load applied; extending the arm and legs of the crane accordingly. the crane can easily tip over if the load is too far away from the crane’s center of gravity. therefore, when moving a heavy object (like an engine), keep the load as low to the floor as possible; to minimize the risk of tipping the crane over.

how can you minimize the risk of tipping the crane over?
shorten the crane’s legs as much as possible.
keep the load close to the crane’s center - of - gravity.
extend the crane’s arm as far as possible.

Explanation:

The text states that the crane can tip over if the load is too far from the center - of - gravity. Keeping the load close to the crane's center - of - gravity reduces this risk. Shortening the legs or extending the arm as far as possible is not mentioned as a way to minimize tipping risk, and in fact, extending the arm too far might increase the risk.

Answer:

Keep the load close to the crane's center - of - gravity.
