If you are planning to purchase lifting clevis hooks, it is important to understand that various options are available and how to choose the best option for your particular application. Lifting clevis hooks are typically used as attachments for various types of cargo loading and lifting equipment, including lifting cables. Although a tremendous amount of focus is often placed on the cables or chains, clevis hooks are also vital in securing equipment for lifting and loading.
First, it should be understood that lifting clevis hooks are available in varying sizes. Sizes typically range between ¼ inches and 7/8 inches. Along with considering the size of the clevis hook, it is also important to take into consideration the grade of the hook. Just as lifting chains are available in various grades, hooks are also available in various grades. This is important to note because different grades may be used for different purposes and usually carry different weight limit capacities. For instance, a Grade 70 clevis hook might be fine for towing, but it would not necessarily be suitable for overhead hanging, an application that would require a Grade 80 hook. The same is also true when choosing a clevis hook for overhead lifting. Make certain to check the weight limit of the load to be lifted to ensure that the clevis hook is rated appropriately for that weight limit. It is vital to ensure that you do not exceed maximum weight limits in order to avoid the potential of the load being dropped.
It is also important to ensure that the lifting clevis hook you select is compatible with the chain to which it will be attached. This will help to ensure maximum efficiency for the entire cargo control system.
Lifting clevis hooks may be categorized as sling hooks, grab hooks, or self-locking hooks. Each type of hook is available in varying sizes to ensure the right fit for the right job.
