Full title and description

St ISO 8686-2:2018 — Cranes — Design principles for loads and load combinations — Part 2: Mobile cranes. This part applies the general principles of ISO 8686‑1 to mobile cranes and gives loads and load combinations suitable for proof-of-competence calculations of mobile‑crane steel structures used in normal and duty‑cycle service.

Abstract

ISO 8686‑2:2018 specifies principles and numerical values of loads and load combinations for mobile cranes (as defined in ISO 4306‑2) to be used in structural proof‑of‑competence calculations. It is intended for normal and duty‑cycle service of mobile cranes; specific means for proof‑of‑competence testing are addressed in other documents.

Scope

Provides the loads and load combinations derived from the general framework in ISO 8686‑1 and tailored to mobile cranes (terms and type definitions taken from ISO 4306‑2). The document is applicable to the structural (steel) components of mobile cranes for normal and duty‑cycle service and is intended to be used in proof‑of‑competence calculations. It does not prescribe test methods for proof‑of‑competence (these are covered elsewhere).

Key topics and requirements

• Definition and classification of loads applicable to mobile cranes (self‑weight, hoisting loads, payloads, traffic and wind loads, lifting‑operation‑related loads).
• Load combination principles (regular, occasional and exceptional combinations) for structural assessment and proof‑of‑competence.
• Application of dynamic load factors and guidance on conservative combination for elastostatic and rigid‑body kinetic approaches.
• Requirements and parameter ranges for use by more specific crane‑type standards and for agreement between purchaser and manufacturer where no specific standard exists.
• Reference to crane vocabulary and definitions from ISO 4306‑2 to ensure consistent terminology.

Typical use and users

Used by crane designers and structural engineers, OEMs and manufacturers of mobile cranes, verification and testing laboratories, classification societies, regulatory authorities, and purchasers preparing technical specifications. It is applied during design checks, structural proof‑of‑competence calculations and when establishing load cases and combinations for certification.

Related standards

Closely related to ISO 8686‑1 (Cranes — Design principles for loads and load combinations — Part 1: General) and to ISO 4306‑2 (Cranes — Vocabulary — Part 2: Mobile cranes) for terminology and definitions; it also works with other crane‑specific standards and national rules that specify test procedures or additional load cases.

FAQ

Q: What is this standard?

A: ISO 8686‑2:2018 is an International Standard that specifies design principles for loads and load combinations specifically applied to mobile cranes to support structural proof‑of‑competence calculations.

Q: What does it cover?

A: It defines the types of loads, recommended combinations and parameter values to be used for assessing the steel structures of mobile cranes in normal and duty‑cycle service; it builds on the general framework in ISO 8686‑1 and uses terminology from ISO 4306‑2.

Q: Who typically uses it?

A: Structural and design engineers, crane manufacturers, conformity assessment bodies, testing laboratories, classification societies and procurement specialists specifying technical requirements for mobile cranes.

Q: Is it current or superseded?
