Full title and description

ISO 8686-4:2005 — Cranes — Design principles for loads and load combinations — Part 4: Jib cranes. This part applies the general design principles of ISO 8686-1 specifically to jib-type cranes and defines the loads and load combinations to be used for strength and proof-of-competence calculations of the steel structures of jib cranes.

Abstract

ISO 8686-4:2005 presents load cases and combinations appropriate for jib cranes (jib-type cranes other than offshore, tower, mobile, railway, gantry and overhead cranes) and adapts the principles given in ISO 8686-1 for use in verification of steel crane structures. It is intended to be used in structural design and verification (proof-of-competence) calculations.

Scope

Specifies design loads and load combinations for jib cranes by applying the general principles of ISO 8686-1 to this crane type. The standard covers jib cranes except offshore cranes, tower cranes, mobile cranes, railway cranes, gantry cranes and overhead cranes (which are dealt with in other parts of the ISO 8686 series and related standards). It is intended for use when performing structural verification and proof-of-competence calculations for the steel parts of jib cranes.

Key topics and requirements

• Application of ISO 8686-1 design principles specifically to jib-type cranes.
• Definition of characteristic loads (working loads, self-weight, dynamic effects, lifting gear influences) relevant to jib cranes.
• Prescribed load combinations for proof-of-competence and structural verification of steel components.
• Exclusions and applicability notes identifying crane types covered by other parts of ISO 8686 and terminology given in ISO 4306-1.
• Guidance to support consistent calculation practice for manufacturers, designers and conformity bodies.

Typical use and users

Used by crane designers and structural engineers performing strength and verification calculations for jib cranes, by crane manufacturers during design and certification, by inspection and certification bodies for proof-of-competence assessments, and by researchers or standards bodies referencing load and combination principles for jib crane structural work.

Related standards

Directly related to ISO 8686-1 (general design principles for loads and load combinations). Terminology and crane type definitions are referenced to ISO 4306-1. Other parts of the ISO 8686 series cover different crane types and may be used together with this part where appropriate.

FAQ

Q: What is this standard?

A: ISO 8686-4:2005 is the part of the ISO 8686 series that sets out design principles for loads and load combinations specifically applicable to jib cranes.

Q: What does it cover?

A: It covers the loads and prescribed load combinations to be used in structural verification and proof-of-competence calculations for the steel structures of jib cranes, applying the general rules given in ISO 8686-1 and excluding crane types covered by other parts of the series.

Q: Who typically uses it?

A: Structural and mechanical engineers, crane manufacturers, testing and certification bodies, inspection authorities, and standards/technical committees working on crane safety and design.

Q: Is it current or superseded?

A: The original publication date is 12 January 2005 (Edition 1). The ISO record shows the standard has been subject to periodic review and was confirmed as current in ISO systematic reviews (most recent confirmations recorded in the ISO record), so this edition remains the valid publication unless ISO publishes a new edition. Users should consult the ISO bibliographic record or their national standards body for the absolute latest status before regulatory or contractual application.

Q: Is it part of a series?

A: Yes — it is Part 4 of the ISO 8686 series (Design principles for loads and load combinations) and is intended to be used in conjunction with ISO 8686-1 (general principles) and other parts of ISO 8686 that address other crane types. Terminology references are given in ISO 4306-1.

Q: What are the key keywords?

A: Jib crane, loads, load combinations, crane design, structural verification, proof-of-competence, ISO 8686.
