▌ INDUSTRY BRIEFING · SEPTEMBER 2026 · EU & UK CRANE SAFETY
Crane safety rules are moving from the steel to the software
Two documents now sit in front of anyone who fits, buys or retrofits safety equipment on a tower crane. From 20 January 2027, Regulation (EU) 2023/1230 replaces the Machinery Directive across the European Union and, for the first time, puts safety-related software, cyber-safety and self-learning safety functions inside the conformity assessment. In Britain, the existing framework already says something different — that the same electronic devices must never become the primary means of keeping two cranes apart.
The two positions are not in conflict. But holding both at once is quietly becoming part of the job of specifying, supplying and installing this equipment.
▌ 01 THE TWO DATES THAT MATTER
One change coming, one already in force
▌ 20 JANUARY 2027 · EU Regulation (EU) 2023/1230 applies, repealing Directive 2006/42/EC — the text most crane technical files still cite. It is a regulation, not a directive, which means it applies directly in every member state with no national transposition. The same wording governs a crane in Rotterdam and a crane in Palermo. Machinery placed on the EU market before that date follows the old directive; anything placed afterwards follows the new regulation.
▌ ALREADY IN FORCE · UK There is no single British equivalent. The framework is LOLER 1998, HSE guidance on lifting operations, BS 7121-5:2019 for tower cranes, and the Construction Plant-hire Association's Tower Crane Interest Group technical notes. All of it applies to a crane on a British site today, with or without a deadline.
▌ 02 WHAT THE EU REGULATION PUTS IN SCOPE
The machine is no longer the whole product
The regulation reaches past the crane itself. Alongside the machine it covers safety components, lifting accessories, interchangeable equipment and partly completed machinery — so a hook block, a grab or a wire rope assembly carries its own compliance route. For safety electronics fitted to a tower crane, four changes matter most.
▌ CYBER-SAFETY The Commission lists provisions covering compliance-relevant software and safety control systems, and machinery carrying AI-powered safety functions. Network connections, remote access, software changes and unauthorised interference all have to be considered in the risk assessment, because any one of them can alter a safety parameter.
▌ DOCUMENTATION Technical documentation may need to show programming logic, system capabilities and limitations, and the development, testing and validation process behind the software. Where it is needed to verify compliance, national authorities may ask for the source code or the programming logic of safety-related software.
▌ HIGHER-RISK CATEGORIES Safety components with fully or partly self-evolving, machine-learning behaviour used to perform safety functions are listed in Annex I, Part A. For those, assessment on internal production control alone is no longer available — a notified body or an approved quality assurance system is required.
▌ PRACTICAL EFFECT A file that records performance levels to EN ISO 13849-1 and a controlled software-update path holds up better in an audit. Instructions may be supplied digitally, but the manufacturer must keep them downloadable, storable and printable, and accessible for the expected life of the machine and at least ten years after it is placed on the market.
▌ 03 THE CLAUSE THAT CATCHES RETROFITS
Who becomes the manufacturer after the fitment
The regulation introduces the concept of substantial modification. Where machinery already in service is changed — physically or digitally — in a way the original manufacturer did not foresee, and that change creates a new hazard or increases an existing risk enough to call for significant new protective measures, the modification can be treated as substantial. The party that carried it out may then be regarded as the manufacturer, owing a fresh conformity assessment before the machine goes back to work.
Read that against ordinary practice on a construction site: a monitoring unit, an anti-collision box, a hook camera and a sensor package added to a crane that was never designed to carry them. Control retrofits land on the integrator, not on the original builder.
Two consequences follow. Whoever fits the equipment needs the paperwork to show the modification was foreseen, or assessed as it was carried out. And the technical file has to be handed to the crane's owner at the end of the job — not left sitting in the installer's mailbox.
▌ 04 BRITAIN'S OPPOSITE EMPHASIS
Fit it, check it, sign it — and still do not trust it alone
The Approved Code of Practice to Regulation 6 of LOLER is blunt about the starting point: where two or more items of lifting machinery are used, they should be installed or positioned so as to prevent the loads and parts of the equipment coming into contact with one another. HSE guidance adds that motion limiting and anti-collision devices can be fitted to stop a boom or counter-boom moving into a dangerous position — with the caveat that even where such devices are fitted, a safe system of work should always be followed.
BS 7121-5:2019 puts detail on that principle.
▌ WHEN THEY SHOULD BE FITTED Zoning, radius-limiting and anti-collision devices should be fitted where the risk assessment identifies a risk of cranes or fixed load attachments entering or oversailing a prohibited zone, exceeding a specified radius, or colliding with fixed structures, other cranes or other mobile plant.
▌ SECONDARY ONLY The safe system of work should not rely on electronic aids as the sole means of avoiding collisions. They are there to assist the crane coordinator, not to replace the coordination.
▌ CHECKED AND SIGNED Functioning, including calibration, is confirmed during daily and weekly pre-operational inspections, and the check is signed for by the operator. Many systems let a check-point be created and compared with the physical position on site, and record it in the system's memory.
▌ RADIO AS WELL For multiple tower crane installations an anti-collision radio system should be installed: a separate radio in each cab on a unique frequency, giving open, unimpeded communication between all the crane operators, the crane coordinator and anyone else with a role in preventing a collision. It is worth noting why — in the event of one jib approaching the hoist rope of a higher crane, the operator of the higher crane can warn the lower one immediately.
So the British position is not that the electronics are unimportant. It is that they sit inside a system of work, next to a radio channel and a signed daily check — never in place of them.
▌ 05 WHAT A ZONING SYSTEM IS SUPPOSED TO DO
The vocabulary that ends up in specifications
The CPA's Tower Crane Interest Group technical note TIN 010 defines the terms used in this field. Because these are the words that appear in tender documents and risk assessments, the definitions are worth knowing precisely.
▌ ZONING SYSTEM Slows and restricts movement of the crane, and can be programmed to prohibit the hook from entering a prohibited area — a railway, for example, or land the crane user has no right to oversail.
▌ ANTI-COLLISION SYSTEM Fitted to two or more adjacent cranes, preventing a crane from colliding with the structure or hoist rope of a neighbouring one.
▌ APPROACH ZONE The zone in which crane motion is automatically slowed and stopped as it reaches the buffer zone.
▌ BUFFER ZONE / SAFETY DISTANCE The gap between the approach zone and the prohibited area or adjacent crane structure — sized to allow for mast deflection, adverse wind effects, load size and load swing.
That last definition is where real sites most often go wrong: a buffer zone copied from a template job, with no allowance for the load swinging on the way in.
There is a legal edge to it as well. In England a landowner's property includes the airspace above it, so a jib entering that airspace without permission is a trespass; where a public highway is oversailed, a licence is a statutory requirement under the Highways Act 1980. Local authority licences typically take at least three months and private landowners often longer — which means the prohibited zones a zoning system will be configured to respect are usually decided long before the equipment arrives on site.
▌ 06 WHY IT IS NOT ACADEMIC
What the enforcement record looks like
HSE investigations into tower crane failures have produced penalties well into six figures. In the Battersea crane collapse in London in 2006, HSE identified failures in the management and inspection of a crane fleet; the financial penalty came to £750,000, with a further £100,000 in costs, and the company involved later entered dissolution.
The wider record is worse than the fines suggest. Failures at Battersea, Worthing, Liverpool and Crewe resulted in multiple fatalities and serious injuries, and a jib collapse at a West London housing development forced the evacuation of neighbouring properties. Alongside the regulatory penalty come civil damages that can run into millions, injunctions, programme delays, higher insurance premiums and reputational damage — and a site that cannot work while the crane is out of service.
What the enforcement pattern shows is consistent. It is rarely the steel that fails first. It is the inspection record, or the management system around the machine — both of which are exactly what the new European documentation rules are designed to make visible.
▌ 07 BEFORE YOU SPECIFY OR BUY
Six questions that hold up in an audit
● Is the safety-related software documented? Ask for the development, validation and update path, and a performance level to a recognised standard rather than a claim in a brochure.
● Who becomes the manufacturer when it is retrofitted? Get the modification route in writing before the fitment, not after an inspector asks about it.
● Is the device inside a safe system of work, or being asked to replace one? A monitoring system that only makes sense if the coordinator, the radio and the daily check are dropped is not a system a British site can run.
● Can the operator check and sign the calibration? Daily and weekly, in the form the regulation expects — a screen anyone can reach, and a record that persists.
● Are the zones configured for this site? Mast deflection, wind, load size, load swing. Not a buffer zone imported from the last project.
● Who holds the technical file — and can they produce it? After 20 January 2027 that question stops being rhetorical.
One caveat, and it is the important one: local rules still govern your site. What follows here is a summary of published European and British material, written for people specifying equipment — not a substitute for your own regulations, your appointed person, or your own risk assessment.
▌ 08 WHAT TO WATCH
Five things likely to matter next year
● Plan around 20 January 2027 now. Technical files, declarations and conformity assessment take time to assemble; suppliers who work to the new text early will have far fewer surprises in January.
● Digital modification keeps moving toward the manufacturer's side of the line. A firmware update that changes a safety parameter is precisely what the new text is aimed at.
● Documentation is becoming part of the product. Software validation records and programming logic are not things a site can assemble after an incident.
● The British position on electronic aids is unlikely to soften. Treat the radio channel, the crane coordinator and the signed inspection log as part of the specification too.
● Buy against the next version of the rules. Equipment chosen only to satisfy today's text tends to be replaced before it wears out.
