How To Know Slings Loads?

Webbing slings and round slings serve as essential tools for securely lifting goods and cargo, distinguishable by their distinct appearances:webbing slings are flat, while round slings exhibit a tubular shape. Not only are they indispensable for lifting loads, but they also prove invaluable in restraining heavy weights. However, the crucial question remains: how can we safely utilize these slings? What precautions should we take, and what is the maximum workload limit for a round sling used for load restraint?

What Are Webbing Slings and Round Slings?

Webbing slings and round slings are both utilized for lifting and securing loads. The key distinction lies in their appearance, where round slings resemble tubular loops. Polyester slings outperform their metal counterparts, like chains, in numerous aspects. They boast a lighter weight, occupy less space, are simpler to maintain and inspect, pose less safety risks, are corrosion-resistant, and are notably more cost-effective.

Regarding lifting equipment

Each unit incorporates a safety factor comprised of two digits, primarily 7:1 and 5:1. The minimum breaking load for a sling with a 7:1 safety factor is precisely seven times greater than the indicated load. Put simply, a round sling rated for 2 tonnes should withstand up to 14 tonnes before failing. On the other hand, lifting equipment with a 4:1 or 5:1 safety factor is categorized as one-time use equipment, implying it’s intended for a single lifting cycle: once for loading and once for unloading, followed by disposal.

SLING COLOURS

The workload limit of a specific webbing or round sling can be discerned by observing its color. While this color-coding system is globally adopted, it’s crucial to note that it’s not applicable to all slings. Hence, it’s paramount to verify the WLL (Work Load Limit) indicated on the label, which supersedes the sling’s color. Furthermore, the label’s color also signifies the sling’s material composition, with green labels representing Polyamide (PA), blue for Polyester (PES), and brown for Polypropylene (PP) slings.
