Comparing Hitch Types: Understanding Lifting Capacities.

The three basic hitch types - single vertical, choker, and basket - are commonly used in lifting and rigging operations. Each hitch type offers distinct advantages and considerations based on the load's characteristics, weight distribution, and desired lifting configuration. Let's compare these hitch types to understand their features and applications:

1. Single Vertical Hitch: The single vertical hitch is the simplest and most common hitch type. In this configuration, the lifting sling or rope is attached directly to the load's lifting point, creating a straight vertical line. This hitch provides the maximum lifting capacity compared to the other two hitch types. It is suitable for loads with a well-defined and centered lifting point, evenly distributed weight, and minimal risk of slippage or movement during lifting.

2. Choker Hitch: The choker hitch involves wrapping the lifting sling or rope around the load with one end passing through the other end's loop, creating a choker configuration. This hitch is suitable for loads that have a small diameter or irregular shape, making it challenging to secure with other hitch types. The choker hitch provides a secure grip around the load, preventing it from slipping or sliding during lifting. However, the choker hitch typically offers the least amount of lifting capacity among the three hitch types due to the increased stress and reduced effective angle of the sling.

3. Basket Hitch: The basket hitch involves passing the lifting sling or rope around the load so that both ends of the sling are connected to the lifting device, forming a basket-like configuration. This hitch type provides stability and even load distribution, making it suitable for loads with a broad or large surface area. The basket hitch offers good control and balance, especially for loads that are not easily secured by other hitch types. It provides a higher lifting capacity compared to the choker hitch, but it may have a slightly reduced capacity compared to the single vertical hitch due to the additional stress on the sling caused by the spread legs.

When selecting the appropriate hitch type, factors such as load shape, weight distribution, lifting point accessibility, load stability, and equipment limitations should be considered. It is crucial to follow industry standards, manufacturer guidelines, and rigging best practices to ensure safe and efficient lifting operations.

By understanding the characteristics and applications of these three basic hitch types - single vertical, choker, and basket - operators can make informed decisions in selecting the most suitable hitch for their specific lifting requirements.

Among the three basic hitch types, the choker hitch typically provides the least amount of lifting capacity.

The choker hitch involves wrapping the lifting sling or rope around the load with one end passing through the other end's loop, creating a choker configuration. In this hitch, the load's weight can exert significant pressure on the sling, reducing the overall lifting capacity.

Compared to the single vertical and basket hitches, the choker hitch places more stress on the sling due to the increased angle between the sling and the load. This increased angle results in a reduction of the effective lifting capacity of the sling.

It's important to note that the actual reduction in lifting capacity can vary depending on factors such as the angle of the choke, the type and condition of the sling, and the load's characteristics. The reduction in capacity is typically determined using recognized industry formulas or charts specific to the type of sling and hitch being used.

When rigging a load, it is crucial to carefully evaluate the lifting requirements and select the appropriate hitch type while considering the load's shape, weight distribution, and the lifting equipment's limitations. Adhering to proper rigging practices and following manufacturer guidelines will ensure safe and efficient lifting operations.
