slingsystem

A slingsystem is a rigging arrangement used to attach a load to a lifting device, such as a crane or hoist, enabling safe handling of materials. It consists of slings, attachments, hardware, and the procedures used to rig and lift loads. Slingsystems are used in construction, manufacturing, shipping, and warehousing to move loads with control and balance.

Slings come in several families, including fiber rope slings (nylon or polypropylene), web slings (polyester), chain slings (carbon steel), wire rope slings, and metal mesh slings. Slings are equipped with hooks, shackles, eyebolts, or couplers for attaching to loads and lifting devices. Each sling is rated by a working load limit (WLL) or rated capacity, and carries marks indicating size, material, and inspection status.

Common configurations influence load sharing and sling strength. Vertical, choker, and basket hitch are typical arrangements, and the choice affects stability and wear. Ensure loads are balanced and aligned with the lifting gear; protect edges with padding or edge guards; avoid sharp corners and pinch points. Before lifting, inspect slings and hardware for cuts, fraying, deformation, corrosion, heat damage, and improper marks. Do not use damaged slings or place yourself under a suspended load; maintain a clear exclusion zone and communicate during the lift.

Standards and regulations govern rigging practices, including inspection intervals, markings, training, and safe use. Follow manufacturer instructions and applicable local rules (for example, OSHA in the United States or corresponding European and international standards). Regular inspection by qualified personnel is required to ensure ongoing safety.
