Question 602 Deck General

The correct answer is D) Topping lift. The topping lift is the proper equipment used to adjust the height of a cargo boom. The topping lift is a line or wire attached to the top of the boom that can be used to raise or lower the boom's position. This allows the operator to control the height and angle of the boom, which is crucial for safely and effectively loading and unloading cargo. The other options are incorrect because they do not serve the function of adjusting the boom height. A lizard is a type of small reptile, a spanner guy is a support line for the boom, and a working guy is a line used to control the movement of the boom during operation.
