How are belts in a 2:1 system routed?

In a 2:1 system, the routing of belts is designed to optimize the lifting mechanism's efficiency and stability. The correct routing is similar to how ropes are handled in traditional hoisting systems. In this setup, the belts pass over sheaves—essentially pulleys designed to guide and change the direction of the belt or rope—ensuring they move smoothly and can bear the load effectively.

Anchoring the belts at dead-end hitches provides a secure point of termination, which is crucial for safety and functionality. This method allows for the even distribution of forces throughout the system, minimizing wear and increasing reliability.

Other choices do not accurately reflect the mechanical principles governing a 2:1 hoisting system. For instance, random routing would lead to decreased efficiency and potential operational hazards. Strapping belts directly to the car or looping around the counterweight would not allow for the required mechanical advantage or support for load balancing, both of which are vital in an effective 2:1 system. Thus, proper routing via sheaves and dead-end anchoring is essential for maintaining a safe and efficient hoisting mechanism.
