Full title and description

ISO 10533:1993 — Earth-moving machinery — Lift-arm support devices. Specifies performance, test, installation, storage and colour requirements for mechanical lift‑arm support devices used to hold lift arms in the elevated position on loaders, backhoe loaders and skid‑steer loaders for maintenance or servicing.

Abstract

This International Standard gives performance requirements and a test method for mechanical lift‑arm support devices (links, bars or structures including attachment points) fitted to earth‑moving machines where the lift arm must be held in an elevated position for maintenance or servicing. It also covers installation instructions, permanent storage on the machine and marking/colour requirements.

General information

• Status: Published (International Standard; confirmed in recent ISO systematic reviews).
• Publication date: 1993 (first edition published January 1993).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 53.100 — Earth‑moving machinery.
• Edition / version: Edition 1 (1993); Amendment ISO 10533:1993/Amd 1:2005 applies.
• Number of pages: 2 (main document).

Scope

The standard applies to mechanical lift‑arm support devices used on loaders, backhoe loaders and skid‑steer loaders to secure the lift arm in an elevated position for maintenance, servicing or other non‑operational purposes. It specifies required performance and test criteria, installation and storage practices, instructions for use and a colour/marking convention to improve visibility and safety during service operations.

Key topics and requirements

• Performance requirement: devices must resist specified static loads (including working‑circuit forces and factors relating to the mass of attachments and linkage) and, when subjected to lifting action, resist lifting forces without permanent structural failure.
• Test method: a physical test is required for each design to verify the performance clause; device must survive the test without permanent deformation or failure.
• Installation: devices shall be installed so they cannot be dislodged by machine movement or lift‑arm motion; recommended elevated parking positions for maintenance access are described.
• Instructions and storage: installation and safe‑use instructions must be provided and the device (and necessary parts) shall be stored permanently and securely on the machine when not in use.
• Colour/marking: the support device (excluding attachment parts) shall be coloured for visibility (commonly red, or yellow if the machine itself is red) to reduce maintenance risk.
• Referenced measurements and mass definitions: the standard uses related ISO measurement/definitions (e.g., mass measurement methods and earth‑moving machinery dimension definitions) when applying test loads.

Typical use and users

Primary users are manufacturers and designers of earth‑moving machinery, machine service and maintenance departments, safety engineers and regulatory/compliance personnel responsible for specifying and validating safe maintenance supports on loaders and similar machines. The standard is used when designing, testing and documenting lift‑arm support devices and when preparing operator and maintenance instructions.

Related standards

ISO 10533 cross‑references other ISO standards relevant to measurement and machinery definitions (examples noted in the ISO record include standards for mass measurement and earth‑moving machinery dimensions). It is part of the ISO/TC 127 series for earth‑moving machinery; an Amendment (Amd 1:2005) updates some provisions. Users often consider related ISO documents on machine dimensions, mass measurement and other safety/performance requirements when applying ISO 10533.

FAQ

Q: What is this standard?

A: An ISO International Standard that specifies performance, test and safety/installation requirements for mechanical lift‑arm support devices used on certain earth‑moving machines.

Q: What does it cover?

A: Performance requirements and a prescribed physical test method for lift‑arm support devices, plus installation and storage requirements, instructions for use and colour/marking guidance to improve maintenance safety.

Q: Who typically uses it?

A: Machine manufacturers, designers, maintenance/service departments, safety officers and standards/compliance personnel working with loaders, backhoe loaders and skid‑steer loaders.

Q: Is it current or superseded?

A: ISO 10533:1993 is the published first edition (1993) and remains published and confirmed by ISO reviews; an amendment (ISO 10533:1993/Amd 1:2005) applies to the original standard. It is not listed as withdrawn as of the latest ISO status updates.

Q: Is it part of a series?

A: It is part of the body of ISO standards for earth‑moving machinery (ICS 53.100) and is maintained under ISO/TC 127/SC 2; an Amendment 1 (2005) modifies the 1993 text.
