What is the instant pickup load increase for a 16 fpm chain hoist?

The instant pickup load increase for a hoist is a critical concept in rigging and operation, referring to the sudden increase in load as the hoist starts to lift. For a 16 feet per minute (fpm) chain hoist, the standard instant pickup load increase is typically around 20%. This percentage reflects the additional force that the hoist must be capable of handling at the moment the load begins to move.

Understanding this concept is essential in ensuring that the hoist is adequately rated for the loads it will encounter during operation. If the instant load increase exceeds the hoist's rated capacity, it could lead to equipment failure or safety hazards. Thus, recognizing that 20% is the expected instant load increase helps operators and riggers in selecting appropriate hoisting equipment and in making accurate calculations for lift loads to ensure safe practices in theatre and event rigging.
