Why should hoists not be used in tie-down applications?

Using hoists in tie-down applications is not recommended primarily because they may be subjected to shock loading. In tie-down scenarios, the loads can shift unexpectedly, resulting in sudden forces that exceed the normal working limits of the hoist. This shock loading can cause the hoist to fail, leading to potential accidents or equipment damage.

Hoists are designed primarily for lifting and lowering loads vertically, which involves a steady application of force. The mechanics of tie-down applications, however, require the ability to secure or stabilize loads under a variety of dynamic conditions. When subjected to the stress of rapid force changes, the integrity of the hoist can be compromised, making it unsuitable for these types of applications.

In contrast, equipment specifically designed for tie-down purposes is built to handle the stresses of securing loads, thus providing better safety and reliability.
