A flat sling in a choke hitch configuration offers a secure grip on loads that might slip in a vertical lift. But can every flat sling be used this way? The short answer is yes—but with significant capacity reduction and strict application rules. According to EN 1492-1 and ASME B30.9, a choke hitch reduces a sling's working load limit to 80% of its vertical hitch capacity, with additional reductions for angles below 120° at the choke point. This guide explains the capacity factors, proper choke hitch technique, conditions that prohibit choke use, and critical inspection points to ensure safe operation.

A lifting sling that has lost its original color is a common sight on job sites. Many riggers wonder: is it still safe to use? The short answer—according to industry standards—is no. Color fading is a visible indicator of ultraviolet (UV) degradation, which weakens synthetic fibers and compromises the sling's load-bearing capacity. This guide examines what faded color means for sling safety, how to distinguish UV damage from other types of discoloration, and the specific retirement criteria outlined in ASME B30.9 and Washington Administrative Code (WAC) regulations. For rigging supervisors and safety professionals, understanding the implications of a faded sling is essential to preventing catastrophic failure.

A flat sling is one of the most versatile tools in any rigging operation. But when it comes to selecting the right configuration, the choice between eye & eye and endless flat slings can significantly impact both safety and efficiency. Eye & eye slings feature sewn loop ends for quick attachment, while endless slings form a continuous loop that can be rotated to distribute wear. This guide breaks down the structural differences, application advantages, and selection criteria for each type, drawing on industry standards including ASME B30.9 and EN 1492-1 to help you make an informed decision.

A lifting sling that has exceeded its safe service life is a hazard—not a tool. Yet many rigging professionals struggle with a simple question: how often should I replace my lifting slings? The answer is not a single number. It depends on material type, usage frequency, operating conditions, and inspection findings. This guide draws on industry standards (ASME B30.9, EN 1492), manufacturer guidelines, and Lishenflex's manufacturing experience to provide clear replacement criteria. We cover expected service life by sling type, inspection frequencies, retirement signs, and the critical distinction between "age-based" and "condition-based" replacement.

A lifting belt that receives proper care can deliver years of reliable service, while one that is neglected may fail prematurely—often without visible warning. This guide draws on industry standards (EN 1492, ASME B30.9) and Dongfang Lishen's manufacturing experience to provide a complete maintenance protocol for synthetic slings.

Flexible lifting slings, as an important lifting tool, have extensive applications in multiple fields such as industrial production, logistics transportation, and construction. Due to its softness, lightness and portability, flexible lifting slings have been favored by many industries. However, befo
