Not all hoist rings are designed for vertical lifting applications; some of them are designed specifically for pulling applications. Known as side pull hoist rings, they can withstand lateral forces. If you’re looking to buy a side pull hoist ring, however, there are several things you should consider.
Attachment Method
You should consider the attachment method when choosing a side pull hoist ring. One of the most common attachment methods is a threaded rod. As shown in the adjacent photo, some side pull hoist rings feature a threaded rod in the center. You can twist this threaded rod into a threaded hole to attach the side pull hoist ring.
Load Rating
Don’t forget to consider the load rating when choosing a side pull hoist ring. Being that they are used to pull heavy loads from the side, most side pull hoist rings can handle a lot of weight. Nonetheless, some of them have a higher load rating than others. The load rating, of course, is the maximum weight a side pull hoist ring can safely pull. It can range from 800 pounds to 4,000 pounds.
Self-Aligning
You may want to choose a self-aligning side pull hoist ring. Self-aligning essentially means that the side pull hoist ring will rotate and align itself with the direction of the load. If you’re pulling the load from the left, the hoist ring will rotate to the left. If you’re pulling the load from the right, the hoist ring will rotate to the right — assuming it’s a self-aligning side pull hoist ring.
Size
Like all hoist rings, side pull hoist rings are available in different sizes. Some of them are small and compact, whereas others are larger and bulkier. When shopping for a side pull hoist ring, you should choose a size that’s appropriate for the load or load types with which you intend to use it. Make sure the diameter of the side pull hoist ring is big enough for the load or loads.
Material
You should choose a side pull hoist ring that’s made of a strong and durable material. Aluminum typically won’t cut it. While aluminum is lightweight and inexpensive, it’s susceptible to damage when exposed to strong lateral forces. A better choice of material for a side pull hoist ring is steel. Steel hoist rings are strong, durable and long-lasting. And with a black oxide finish, steel hoist rings won’t rust or corrode.
