Overview
IEC 60204-32:2023 - Safety of machinery - Electrical equipment of machines - Part 32 - specifies electrical requirements for hoisting machines (cranes, winches, storage/retrieval machines and related equipment). The standard applies to electrical, electronic and programmable equipment starting at the point of supply connection (the crane-supply-switch) and includes feeders outside the machine (flexible cables, conductor wires or bars). It covers systems up to 1 000 V AC or 1 500 V DC and nominal frequencies not exceeding 200 Hz. This third edition (2023) replaces the 2008 edition and aligns key topics with IEC 60204-1.
Key topics and technical requirements
The standard focuses on electrical safety and functional integrity of hoisting machines. Major technical topics include:
- Scope of equipment: overhead travelling cranes, mobile cranes, tower cranes, gantry/offshore/floating cranes, winches, hoists, loader and cable cranes, RTGs, monorail hoists, storage and retrieval machines, straddle carriers, load-holding devices.
- Point of supply and feeders: requirements starting from the crane-supply-switch and including external feeders and conductor systems.
- Protection against electric shock: basic and fault protection, PELV where applicable, and residual voltage control.
- Equipotential bonding and protective bonding circuits: earthing, bonding continuity and protective conductor requirements.
- Overcurrent and motor protection: circuit protection for supply, power and control circuits; motor overload/overspeed protections.
- Control systems and functions: start/stop categories, emergency stop, interlocks, operating modes, and measures to minimise risks from failures.
- Power Drive Systems (PDS): consideration of PDS, safe torque off, and control circuit protection.
- Cableless control systems (CCS): requirements and safety considerations for radio or wireless controls.
- Electromagnetic compatibility (EMC): EMC requirements for reliable operation and reduced interference.
- Documentation and technical files: updated technical documentation requirements for design, installation, maintenance and compliance.
- Special conditions: additional requirements where machines handle explosive/flammable materials or are used in mines.

The IEC 60204-32:2023 standard is a comprehensive document that addresses the safety of electrical equipment used in hoisting machines. Its scope is notably broad, covering a vast array of hoisting machines such as cranes, winches, and storage and retrieval machines, while ensuring that the safety requirements extend seamlessly across multiple coordinated systems. One of the key strengths of this standard is its alignment with the sixth edition of IEC 60204-1, which brings enhanced specifications on critical aspects like earthing and bonding, circuit protection, and the use of Power Drive Systems (PDS). This alignment not only improves the clarity of safety protocols but also ensures that the guidelines reflect current industry practices and technological advancements. The inclusion of requirements for safe torque off for PDS, alongside emergency stop and control circuit protection, is indicative of the standard's responsiveness to evolving safety needs. Furthermore, the IEC 60204-32:2023 incorporates important additions regarding cableless control systems and electromagnetic compatibility (EMC) requirements, addressing contemporary operational environments where these technologies are increasingly prevalent. Such updates highlight the document's relevance to modern hoisting equipment, which often operates in complex and dynamic environments. Moreover, the standard recognizes and specifies the unique challenges associated with various materials and environments in which hoisting machines operate, such as potentially explosive atmospheres or mines. This segmentation reflects a nuanced understanding of the diverse operational conditions that hoisting machines face, making it a more effective tool for achieving compliance and enhancing safety. Despite its extensive coverage, it is crucial to note that IEC 60204-32:2023 does not encompass all safety requirements, particularly those concerning non-electrical hazards. This delineation emphasizes the importance of cross-referencing with other relevant regulations and standards to maintain comprehensive safety protocols. In summary, the IEC 60204-32:2023 standard stands out for its thorough approach in setting safety requirements for the electrical equipment of hoisting machines. Its combination of historical context, modern updates, and detailed specifications makes it a vital reference point for manufacturers, safety professionals, and compliance officers striving to enhance safety in hoisting operations.
