The main hoist is a key component of a crane or lifting system, responsible for raising and lowering loads. It typically consists of a motor, drum, and wire rope or chain, enabling the secure lifting of heavy materials. The main hoist is essential in construction, manufacturing, and shipping industries, where it enhances efficiency and safety in material handling. Its design and capacity vary depending on the specific application and load requirements.

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.
Hoist is a noun (a hoist) and a verb (to hoist).

A headache ball is a heavy steel ball used to provide ballast on the hook end of a crane hoist rope. Typically some larger cranes have an auxiliary/secondary hoist that can lift light loads but at a much faster speed than the main hoist. A hoist rope needs ballast so that the rope remains tight and does not whip (ballast normally provided by the weight of the hook on the main hoist). Because of the fast speed of these secondary hoists and the common failure of older limit switches it was not uncommon for ropes to be over-wound causing this ballast ball to strike the crane jib and become separated from the rope, dropping to the ground. A crane with a secondary hoist is not normally referred to as a "headache ball crane" but this might be what is meant.
