What type of hoist is used primarily for horizontal pulling?

The correct answer is "Pull-lift" because this type of hoist is specifically designed for horizontal pulling applications. Pull-lifts utilize a mechanism that allows the user to generate significant force horizontally, making them suitable for tasks such as moving heavy loads across a flat surface or for positioning equipment in tight spaces.

In contrast, while pulleys can assist with lifting loads vertically, they are not typically used for horizontal pulling alone. Snatch hoists are commonly employed for lifting and sometimes moving loads, but they are not primarily designed for horizontal pulling. Screw geared hoists, while providing excellent precision and control for lifting, are generally not suited for horizontal movement. Therefore, the pull-lift is the most appropriate choice given its intended purpose and functionality.
