If you are lifting a 1998-pound object from main one, which equipment will you need?

The correct answer is the option that includes "two ply nylon and a 2-ton chain hoist" because it provides both the strength and safety margin needed for lifting an object weighing 1998 pounds. A two-ply nylon lift strap has enhanced durability and load support compared to a single ply, which is crucial when handling heavy loads.

Additionally, a 2-ton chain hoist can support up to 4000 pounds, which comfortably accommodates the weight of the object being lifted. This is important because working with hoists and lifting equipment requires a safety factor to ensure that the equipment can handle loads without risk of failure. Using a hoist that is rated higher than the load ensures greater safety during operations.

In this scenario, while the other options may offer some capacity, they either utilize insufficient lifting power or would not provide the necessary safety margins to safely lift a weight just under 2000 pounds. The requirements for lifting heavy weights emphasize the need for both the material strength of the lifting strap and the weight capacity of the hoist to align appropriately with the task at hand.
