Full title and description

STB UNE-EN IEC 60204-32:2025 — Safety of machinery — Electrical equipment of machines — Part 32: Requirements for hoisting machines. This designation refers to the European adoption (EN) and national publication (UNE) of IEC 60204‑32 (edition 3, 2023) as a 2025 EN/UNE document, providing requirements for electrical, electronic and programmable electronic equipment and systems applied to hoisting machines (cranes, winches, storage/retrieval machines and related equipment).

Abstract

This standard specifies safety requirements and guidance for the electrical equipment of hoisting machines from the point of connection of the supply to the machine’s electrical equipment (crane-supply-switch), including power- and control-feeders outside the hoisting machine. It addresses selection, erection and protective measures for equipment up to defined voltage/frequency limits and clarifies documentation, bonding, control separation and verification requirements to improve electrical safety for hoisting machinery installations.

Scope

This part of IEC/EN 60204 applies to electrical, electronic and programmable electronic equipment and systems for hoisting machines and related equipment, including groups of hoisting machines operating in a coordinated manner. It covers equipment from the point of connection of the supply to the machine electrical equipment (crane‑supply‑switch) and feeders such as flexible cables, conductor wires and conductor bars. The standard is applicable to equipment not exceeding 1 000 V AC or 1 500 V DC between lines with nominal frequencies up to 200 Hz. It does not replace requirements for non‑electrical hazards (guarding, mechanical interlocks, noise/vibration risks) and special environments may require additional standards.

Key topics and requirements

• Application limits (voltage and frequency) and definition of the electrical scope for hoisting machines.
• Requirements for supply connection points, power and control feeders (including selection and erection of cables, conductor bars and flexible connections).
• Equipotential bonding and protective earthing arrangements specific to hoisting equipment.
• Separation of control functions and corresponding devices (control architecture, safety‑related control functions).
• Requirements for control systems including cableless/remote controls and verification of control safety functions.
• Verification of protective measures (e.g., automatic disconnection of supply, protective device selection and testing).
• Technical documentation structure, marking and instructions for installation, inspection and maintenance.
• Notes on exclusions and interfaces with other standards (e.g., IEC 60364 for supply installation, IEC 60204‑11 for higher voltages, ISO 4306‑1 for crane terminology).

Typical use and users

Primary users are manufacturers of hoisting and lifting equipment (crane and winch builders), integrators and electrical designers, factory/port/shipyard safety engineers, inspection bodies, notified bodies and maintenance/service organizations responsible for installation, verification and periodic inspection of electrical equipment on hoisting machines.

Related standards

Relevant cross‑references include IEC 60204‑1 (general requirements for electrical equipment of machines), IEC 60364 (electrical installation rules), IEC 60204‑11 (special requirements for higher voltages), ISO 4306‑1 (crane vocabulary) and other EN/ISO standards dealing with machine safety, lifting appliances and EMC/safety‑related control systems.

FAQ

Q: What is this standard?

A: It is EN/UNE adoption of IEC 60204‑32 (edition based on IEC 60204‑32:2023) titled "Safety of machinery — Electrical equipment of machines — Part 32: Requirements for hoisting machines", giving electrical safety requirements for hoisting machinery.

Q: What does it cover?

A: It covers the electrical scope for hoisting machines from the supply connection to the machine’s electrical equipment, including power and control feeders, selection and erection of electrical components, bonding, protective measures and documentation. It excludes many non‑electrical safety aspects and may require additional standards for special environments.

Q: Who typically uses it?

A: Equipment manufacturers, electrical designers, safety and maintenance teams, conformity assessment and inspection bodies, and any organization that specifies, installs or services electrical systems for cranes, winches and related hoisting equipment.

Q: Is it current or superseded?

A: The EN/UNE 60204‑32:2025 adoption is current (published 2025) and is based on IEC 60204‑32:2023 (Edition 3.0). It replaces earlier national/adopted versions derived from the 2008 edition.

Q: Is it part of a series?

A: Yes — it is Part 32 of the IEC 60204 series ("Electrical equipment of machines"), which includes Part 1 (general requirements) and other related parts; it fits into the broader set of machine safety and electrical installation standards.

Q: What are the key keywords?

A: Hoisting machines, cranes, electrical equipment, machine safety, bonding, control systems, IEC 60204‑32, EN IEC 60204‑32, UNE.
