ISO 20474-15:2019

Overview

ISO 20474-15:2019 - "Earth-moving machinery - Safety - Part 15: Requirements for compact tool carriers" defines safety requirements specific to compact tool carriers (self-propelled, base machine mass < 2 000 kg with pedestrian or standing operator platforms and front-mounted interchangeable equipment). It is a type‑C standard intended to be used together with ISO 20474‑1 (general requirements). Where this part differs, its provisions take precedence. The standard addresses hazards during commissioning, operation and maintenance and is not retroactive to machines built before publication.

Key topics and technical requirements

• Scope & definitions: Defines compact tool carriers, interchangeable equipment, operator platform types, powered attachments and related terms (see ISO 6165 references).
• Operator platform design: Requirements for standing platforms include a slip-resistant surface, maximum height 400 mm, minimum platform area (see standard text for exact dimensions), handholds per ISO 2867, and locking/clearance provisions for folding or ground-supported platforms.
• Operator station and controls: No cab provision allowed; controls must support the operator during travel and work. Devices (handholds) must allow operator support without impeding ingress/egress.
• Powered attachments: Safety interlocks required to remove or prevent reactivation of attachment power when the operator leaves the machine (hold‑to‑run or multi-action reactivation).
• Brakes & travel: Brake system requirements apply; machines with removable/folding platforms that convert to pedestrian use must meet ride‑on machine brake rules.
• Visibility & warnings: Operators must have sufficient visibility for intended tasks; audible horn is not mandatory. Warning devices and safety signs per ISO 20474‑1 apply.
• Stability and testing: Stability rules and tipping‑limit tests are specified; an operator mass of 75 kg is used where operator mass is supported by the machine.
• Maintenance, electrical, fire protection & attachments: Protective measures for electrical/electronic systems, fire protection, coupling of interchangeable equipment and maintenance information are included.

Applications and users

ISO 20474-15:2019 is used by:

• Manufacturers and designers of compact tool carriers to set safe designs and technical specifications
• Safety engineers and risk assessors performing conformity assessments and machine safety reviews
• Test labs and certification bodies verifying compliance with tipping, control and interlock requirements
• Fleet managers and procurement specialists specifying safe equipment for construction, landscaping and utilities
• Training providers and maintenance teams referencing operator platform, control and attachment safety requirements

Related standards

• ISO 20474-1:2017 (General requirements for earth‑moving machinery)
• ISO 6165 (Machine types and terms)
• ISO 2867 (Access systems / handholds)
• Other referenced standards: ISO 14397‑1, ISO 2330, ISO 7546, ISO 6682

Using ISO 20474-15:2019 helps ensure compact tool carriers meet recognized international safety requirements, reduce operator risk, and support compliant machine design and procurement.
