Safety, rules and responsibility as a crane operator

Few trades have safety as central as the crane trade. A crane lifts loads that can kill if they fall, and a crane can overturn. Therefore the rules are strict, and access to operate a crane is controlled. It is not trouble — it is what makes the profession safe.

Cranes with a maximum permitted load over 8 tonnes or 8 tonne-metres may only be operated by persons with a crane operator certificate (BEK no. 1978 of 27/10/2021 §§ 4-6). The certificate can be issued when you have turned 18 — or from 15 if it is a necessary part of vocational training, e.g. the crane operator programme (§ 23). You must also be medically fit. This is documented with your driving licence or the health declaration given when a driving licence is issued (§ 22, subsection 2). The executive order sets no language requirement. But the instructions for use must be in Danish or another language you understand (BFA Bygge & Anlæg).

The two classic causes of serious crane accidents are lack of stability and overload. A crane overturns if it does not stand stably or if the load and reach exceed its limit. Therefore: position the crane on bearing ground set the outriggers correctly and stay within the load curve. You never disable a load limiter to handle 'just that one lift'.

When a mobile crane lifts, measures must be taken so that it cannot tip, overturn or slide — and it must be checked that they work (BEK no. 428 of 05/04/2022 § 52). Overload protection must never be switched off or bypassed (BFA Bygge & Anlæg).

No one may remain under a suspended load, and no one travels with a load unless the crane and equipment are expressly designed for personnel transport under special rules. You keep people away from the lifting zone and stop the lift if anyone comes too close. A load that swings or falls leaves no reaction time.

Measures must be taken so that people do not stay under suspended loads, and loads must not be moved over work areas with people if those areas are not protected (BEK 428/2022 § 45).

A particular hazard is overhead electrical lines: if the crane or cable gets too close, the current can arc over even without contact and be fatal. Therefore safe distance is maintained to power lines and lifts are planned so the load does not pass close to them. Other obstacles — buildings, other cranes, traffic — are also considered before the lift begins.

The fixed distances are in BEK no. 1112 of 18/08/2016: 1.5 m from the outermost conductor at low voltage, 6 m at 10-40 kV and 15 m above 40 kV (§ 5, subsection 3).

Clear communication is a safety rule. Agreed hand signals or radio are used, and only one person gives signals at a time so the driver does not receive conflicting messages. A clear stop signal must always be able to be given and obeyed immediately by anyone who sees a danger. Doubt about a signal means stop, not guess.

When you sit in the crane you're responsible for the lift. That also means you can and must say no to a lift that can't be done safely — too heavy too much wind bad ground or unclear gear. A no from the crane operator is a professional decision nobody should be able to pressure you away from. It's part of the responsibility the certificate gives you.

BFA Bygge & Anlæg puts it plainly: The slinger and the crane operator have the right and the duty to refuse a lift if they have doubts about it.

“In crane work, it is not a weakness to say no to an unsafe lift — it is precisely what your certificate is for.”
