Final answer:
The maximum load that can be lifted by the crane is 1,000 pounds.
Step-by-step explanation:
To determine the maximum load that the crane can lift, we need to consider the weight capacities of each component. The crane is rated for 2 tons, which is equal to 4,000 pounds. The hoist is also rated for 2 tons, or 4,000 pounds. The hook is rated for 1/2 ton, which is 1,000 pounds. And the sling is rated for 2,000 pounds.
We need to find the minimum weight capacity among these components, which is 1,000 pounds for the hook. Therefore, the maximum load that can be lifted by the crane is 1,000 pounds.
