High forces. Most work in the construction industry requires a certain amount of high force to move or lift heavy objects. High forces in construction can also be seen in the pushing, pulling, and gripping of tools. All these can lead to some ergonomic issues that might affect the work.

This means the input force on the rope is F A =F B /n. Thus, the block and tackle reduces the input force by the factor n. A double tackle has two pulleys in both the fixed and moving blocks with four rope parts (n) supporting the load (F B) of 100 N. The mechanical advantage is 4, requiring a force of only 25 N to lift the load.
