Rated Capacity - CMack Supply

Rated Capacity

The lifting hardware, shackles, turnbuckles and eye bolts sold by C-Mack Supply can be used in a variety of applications and situations.  As we have no control as to how our products are used we assume that you have taken into account your specific job requirements, the working load/rated capacity needed, as well as the knowledge and expertise of the person installing the product before making a purchase.  Safety should be PRIORITY ONE.

Machinery Lifting Eye Bolts and Swivel Hoist Rings are the only eye bolts specifically designed for lifting.  Most are used in blind holes in dies, molds, and/or machines where the size of the threaded hole was engineered specifically to support the need to lift the item.  Taken into account should be the weight, angle of the lift and a Safety Factory to accommodate jerking motions, swings or other situations that may enter into the process while lifting.  It is impossible for C-Mack Supply to know or advise as to your individual application or use, however the following tables by help to provide a better understanding of making a lift:

The Rated Capacities shown for our products may be higher than what is identified in the chart, but the percentage of capacity lost as the angle of a lift increases remains fairly consistent; a vertical lift is always best.  Further, the position of the eye bolt is equally important.  The following diagram provides valuable advice:

Most products have a stated Rated Capacity or Working Load Limit noted.  The rating is intended to be the maximum stress placed upon the product in its application/use.  Do not exceed the capacity of the product.  For additional information there is a wealth of information as to the safe use of all rigging, lifting and suspension products, applications and uses.  Please see the following sites as a small example of what is available to insure your project is done safely:
