Chain grades most often used for overhead lifting and rescue are Grades:

The selection of Grades 80 and 100 for overhead lifting and rescue operations is appropriate due to their higher strength-to-weight ratios and durability. These grades of chain are specifically designed for heavy-duty applications, making them ideal for scenarios that demand reliability and strength, such as lifting and rescue operations.

Grade 80 chain is particularly recognized in the industry for its enhanced performance, as it is often used in lifting and rigging applications. It has a minimum proof test strength of 8,000 pounds per ton of capacity, making it significantly stronger than lower-grade chains. Grade 100 takes it a step further, featuring an even higher tensile strength, solidifying its use in critical rescue operations where safety is paramount.

The use of Grade 80 and 100 chains ensures that the equipment meets the stringent requirements necessary for the forces encountered during lifting or rescue scenarios. This level of quality helps prevent equipment failure, which is essential in maintaining safety for rescuers and individuals being rescued.
