Описание (английский):

This second edition cancels and replaces the first edition (ISO 3056:1974), of which it constitutes a technical revision. Constitutes a guide to the selection, use, inspection, testing, maintenance and repair of non-calibrated, round steel, short link chains and chain slings. Lifting chains and chain slings may be governed by national and local laws and regulations.

Overview

ISO 3056:1986 - "Non-calibrated round steel link lifting chain and chain slings - Use and maintenance" is an ISO guidance standard for the selection, use, inspection, testing, maintenance and repair of non‑calibrated, round‑steel, short‑link lifting chains and chain slings. It updates the 1974 edition and complements product and assembly specifications in related ISO chain standards. The document emphasizes safe use, reduction of risk from improper handling and environmental effects, and the roles of operators and competent inspectors.

Key topics and requirements

Scope and chain types: Applies to non‑calibrated short‑link round steel chains manufactured per related ISO product standards (e.g., ISO 1834, 1835, 3075, 3076).

Working load limit (WLL): WLL must be marked on slings and is determined by chain size and grade, sling geometry (number of legs and angles), and method of rating (uniform load or trigonometric methods per ISO 4778/ISO 7593).

Grades and strength: Chains are grouped by grade (M(4), S(6), T(8)); higher grades permit smaller nominal sizes for the same strength.

Geometry and angles: Included branch angles affect load per leg; use of sling legs at angles greater than 60° to the vertical (included angles >120°) is not recommended.

Environmental derating: The standard provides guidance on temperature effects (e.g., service down to –40 °C without reduction) and warns against use of certain grades in acidic or aggressive environments unless manufacturer guidance exists.

Inspection regime: Two-tier inspection - frequent inspections (operator or designated personnel) and periodic inspections (thorough examination by a competent person with records). Withdraw slings showing stretch, wear, cracks, distortion, illegible markings or heat damage.

Handling and misuse to avoid: Guidance on correct hitching (basket, choke), packing to prevent damage, and prohibitions against common malpractices such as loading on the point of a hook, wrapping chains around hooks, using lower‑grade components, or connecting links with bolts/wire.

Practical applications

ISO 3056:1986 is practical guidance for organizations that use or maintain lifting chains and chain slings:

Lifting and rigging operations in construction, manufacturing, shipping, mining and heavy engineering

Maintenance teams and safety managers establishing inspection and maintenance programs

Equipment users (crane operators, riggers) for daily checks and correct hitching practice

Health & safety and compliance officers aligning procedures with international guidance
