SIST EN ISO 19472-2:2022 PDF

Overview

EN ISO 19472-2:2022 - Machinery for forestry - Winches - Part 2: Traction aid winches (CEN adoption of ISO 19472-2:2022) defines the dimensions, performance and safety requirements for traction aid winches used in forestry to assist supported machines when going uphill and downhill (pulling and braking). It covers fixed, detachable and remote traction aid winch systems, their components, connections and communications, and requirements for assembly with the supported machine. The standard is applicable regardless of the winch prime mover and is not applicable to certain winch types (e.g., skidding, crane hoisting, rope logging) or equipment manufactured before its publication.

Keywords: EN ISO 19472-2:2022, traction aid winches, forestry winches, winch safety, winch standards.

Key topics and technical requirements

This standard addresses practical and safety-critical aspects, including:

• Design and mechanical safety: dimensions, mechanical stability and modes of operation.
• Rope system requirements: rope drive, steel wire ropes and rope end connectors.
• Attachment and assembly: anchor points, combination of supported machine and winch, remote installation considerations.
• Brake and control systems: brake design, controlled rope force for downhill braking, operator controls, starting/stopping and emergency stop.
• Control and communications: safety-relevant functions, operation mode control and remote-control systems.
• Electrical and energy safety: electrical protection and alternative energy supply considerations.
• Risk management features: anchor monitoring, hazard zones, guards and prevention of uncontrolled movements.
• Human factors and environment: ergonomics, access, noise and vibration limits, fire risk mitigation, maintenance and marking.
• Documentation and user information: required warnings, instructions and marking for safe operation.

Applications and practical value

EN ISO 19472-2:2022 is used to:

• Guide manufacturers in designing traction aid winches that meet harmonized safety and performance benchmarks.
• Help safety engineers and designers evaluate winch assemblies, remote systems and attachment solutions for forestry and compatible earth-moving machines.
• Support inspection bodies, procurement teams and operators in verifying conformity, safe installation and safe operation on slopes.
• Provide a route to demonstrate conformity with applicable machinery regulations (see relation to EU Directive 2006/42/EC in Annex ZA).

Practical benefits include reduced risk of uncontrolled movements on slopes, clearer specifications for component compatibility, and improved operator safety during uphill/downhill assistance.

Who should use this standard

• Winch and forestry machine manufacturers
• Machine designers and integrators
• Safety assessors, certifiers and conformity assessors
• Forestry contractors and operators specifying equipment
• Regulators and procurement authorities
