It is a type of machine that is changing the direction over which a force is exerted.
A flag hoister
The chain hoist has either a lever to power the hoist or a loop of operating chain pulls through the block of the hoist which then powers the block that takes up the main lifting chain.

This is referrred to as exercising a simple machine called a pulley.
yes, you would be using a pulley which is a type of simple machine. It is a type of machine that is changing the direction over which a force is exerted.
Not unless there's a pulley involved.

Lever Hoist
Hoist can be a verb or a noun. As a verb, it means to raise up or lift, especially by means of a tackle. As a noun, it can mean either a machine or device used to lift heavy objects or the act of hoisting. Here are some sample sentences.As verb:"The movers knew the biggest effort would be when it came time to hoist the grand piano into the moving van.""He hoisted his little brother over the fence.""The sailors hoisted the sail."As a noun:"The young girl needed a hoist to get on the balance beam.""The men used a hoist to load the truck."
Hoist is a noun (a hoist) and a verb (to hoist).
On a large crane, there are usually three hoists; The main hoist, auxiliary hoist, and the whip hoist. The whip hoist is the one attached to the furthest tip of the crane and has the smallest capacity. The Auxiliary hoist has slightly more capacity, and is located between the main hoist and the whip hoist. The main hoist is the biggest hoist on the crane and also determines the maximum weight, the crane can lift.
A chain hoist uses gears to multiply force.A chain hoist is operated by hand. An operator pulls the light loop chain on the side of the chain hoist. This turns a gear mechanism inside the chain hoist housing to turn the chain pulley. When this pulley turns, it raises the heavy chain which usually has a hook on the end. By pulling the light chain loop, the manual hoist is actually able to increase the force that is being applied by the heavy chain. This is caused by the gear ratios inside the manual chain hoist. The mechanical work done by the operator is the same as the work done by the heavy lifting chain.
