What do all chain hoists use to lift heavy loads? anchorage slide __ gear system __ sprocket set __ hook retainer

## Step 1<br />A chain hoist is a device used to lift and lower heavy loads. It operates on the principle of a pulley system, where a chain wraps around a drum. <br /><br />## Step 2<br />The chain wraps around the drum, which is connected to the load. As the chain wraps around the drum, it lifts the load. <br /><br />## Step 3<br />The gear system in a chain hoist is responsible for changing the direction of the force applied to the load. This allows the load to be lifted or lowered.<br /><br />## Step 4<br />The other options, such as anchorage slide, sprocket set, and hook retainer, are not the primary components that allow a chain hoist to lift heavy loads. They may be part of the overall structure of the hoist, but they do not directly contribute to the lifting action.
