What type of hand-operated winching device should never be used for vertical overhead lifting?

The come-along, which is a type of hand-operated winching device, is specifically designed for horizontal pulling rather than vertical lifting. Its construction includes a ratcheting mechanism that provides incremental pulling power, but it lacks the necessary safety features and stability for overhead lifting. Using a come-along for vertical applications can lead to uncontrolled loads, which significantly increases the risk of accidents and injuries.

This type of winch is more suitable for tasks like moving heavy objects across a surface or making adjustments to the position of materials rather than lifting them directly above ground. For overhead lifting, devices like electric hoists, chain blocks, and capstan winches are designed with safety advances that accommodate the added complexities and risks associated with lifting loads above the ground.
