• Use only cranes with the same rated capacity
• Keep the working radius of both cranes identical
• Keep the hoist lines of both cranes vertical CORRECT ANSWER: D) Keep the hoist

lines of both cranes vertical

If lifting a load with two mobile cranes of different rated capacities, the crane with the

larger rated capacity should:

• Be hooked at an equal distance from the loads center of gravity
• Be hooked at a distance closer to the loads center of gravity
• Be hooked at the loads center of gravity
• Be hooked at a distance farther from the loads center of gravity CORRECT

ANSWER: B) Be hooked at a distance closer to the loads center of gravity

D) Follow manufacturers recommendations CORRECT ANSWER: D) Follow

manufacturers recommendations

When performing a multiple crane lift it is important for the operator of each crane to

understand that:

• The weight is equally distributed at all times during the lift
• The weight is never equally distributed during the crane lift
• The weight may increase if the other crane lands the load

D) The weight may decrease if the other crane lands the load CORRECT ANSWER: C)

The weight may increase if the other crane lands the load

When lifting loads that are submerged under water with a mobile crane, what is one of the conditions that the operator should be familiar with?
