What is the purpose of a tackle in rigging?

The purpose of a tackle in rigging is primarily to lift and lower loads more easily. A tackle consists of a system of pulleys and ropes or blocks that allows for the mechanical advantage, making it simpler to move heavy objects. By using a tackle, the amount of force needed to lift a load is significantly reduced, which facilitates safe and efficient handling of materials during rigging operations.

While securing rigging lines, establishing load weight, and managing safety factors are all important aspects of rigging operations, these functions are not the primary purpose of a tackle. The ease of lifting and lowering, enabled by the mechanical advantages provided by the tackle, is the key feature that sets it apart in the context of rigging.
