How would you lift heavy building materials while supervising a multi-storey construction?


In an interview a collegue was asked if he was supervising the construction of a multi storey structure, how would he carry heavy materials up the floors during construction. Though his answer was a ' crane'.
This morning i felt it as an obligation to let us know the answer to that question.
Materials are lifted up from the ground to all others floors by a hoist

A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The load is attached to the hoist by means of a lifting hook.

For high rise buildings these are typically concrete masonry units (blocks) which are brought up on materials hoists



Or in-situ concrete walls which are poured using a concrete placing boom which is usually located in the core of the building and fed by a pipe up inside the lift shaft by a static concrete pump on the ground.
