Hitch Types - Vertical, Choker, Basket & Bridle
Understanding the four fundamental hitch configurations, their capacity factors, and when to use each type.
- Define vertical hitch and explain why it represents 100% rated sling capacity
- Calculate choker hitch reduction factor and identify the critical 120-degree angle
- Explain how basket hitch achieves approximately 2x vertical capacity
- Describe bridle hitch configuration and unequal leg loading effects

Vertical Hitch - Capacity & Application
What Is Vertical Hitch?
A vertical hitch is the simplest sling configuration - a single sling attached vertically between the hook and the load with a straight, plumb pull. The sling hangs directly down from the hook to the load attachment point with no angle, wrap, or choke.
Rated Sling Capacity
Vertical hitch capacity is the rated sling capacity with a straight pull. This is the baseline capacity printed on the sling tag - it represents 100% of the sling's Working Load Limit (WLL). Every other hitch type is measured as a fraction or multiple of vertical hitch capacity.
When to Use Vertical Hitch
Vertical hitch works best when:
- The load has a single designated lift point directly above the center of gravity
- The load will hang straight and balanced from one attachment point
- No wrapping or choking is needed to secure the load
Limitations
Vertical hitch provides no control over load rotation or tipping. If the attachment point is not directly above the center of gravity, the load will tilt. For loads requiring multiple attachment points or anti-rotation control, a bridle or choker hitch is more appropriate.
Exam Terminology
When the exam says "rated sling capacity with straight pull" - that is the definition of vertical hitch capacity. It is the baseline from which all other hitch capacities are calculated.
Vertical hitch capacity equals the rated sling capacity with a straight pull - 100% of WLL. It is the baseline measurement for all other hitch configurations.
