The primary purpose of a limit switch in a material hoist is to prevent over-travel of the hoist. Limit switches are essential safety devices that help ensure the hoist operates within its designed travel limits. When the hoist reaches its maximum height or lowest point, the limit switch is triggered, which stops the hoist from moving further in that direction. This prevents potential damage to the hoisting mechanism, the materials being lifted, and other structures in the vicinity, effectively enhancing safety during operation.

The other options relate to functions that limit switches do not provide. While activating an alarm system, controlling hoist speed, or monitoring load weights are important aspects of hoist operation, the primary function of a limit switch is focused on travel limitation to mitigate the risk of mechanical failures or accidents.
