If you have a hoist rated at 3,000 lbs and use a double block to single block reeving, what is your total lifting capacity?

1,500 lbs
3,000 lbs
6,000 lbs
9,000 lbs

The correct answer is: 1,500 lbs

When using a double block in a single block reeving system, the total lifting capacity is effectively halved. This is because the use of a double block, which consists of two pulleys, redistributes the load across both pulleys. Since each pulley shares the weight, the hoist will provide support for half of the total rated capacity of the hoist. In this case, with a hoist rated at 3,000 lbs, utilizing a double block in a single block reeving setup results in a total lifting capacity of: 3,000 lbs (hoist capacity) divided by 2 (due to the double block) = 1,500 lbs. This reasoning leads us to the correct lifting capacity of 1,500 lbs for this particular reeving arrangement.
