Singapore’s crane rules were not rewritten — the testing calendar was

Singapore has regulated the lifting operation itself through one set of regulations for well over a decade. The Workplace Safety and Health (Operation of Cranes) Regulations 2011, published as S 515/2011 and in operation since 10 September 2011, revoked the older Factories (Operation of Cranes) Regulations and moved crane work squarely under the Workplace Safety and Health Act 2006 — Chapter 354A of the Singapore Statutes, in force since 1 March 2006 and administered by the Commissioner for Workplace Safety and Health at the Ministry of Manpower.

What moved most recently is not the statute but the schedule that hangs off it. On 29 August 2025 the Ministry of Manpower issued circular MOM/OSHD/2025-05, Test and Examination Requirements for Statutory Lifting Equipment. It took effect on 12 September 2025, supersedes MOM/OSHD/2020-01, and changes three things at once: it drops the overload test that used to follow registration, allows workplace occupiers to appoint their own competent persons for periodic lifting-gear re-examination, and stretches the test interval for hoists from six months to twelve. For suppliers and buyers of lifting equipment, the compliance question in Singapore has shifted from what is required to when — and by whom — it is checked.

▌  01  THE TWO DATES

▌  IN OPERATION SINCE 10 SEPTEMBER 2011  The Regulations were published in the Government Gazette, Electronic Edition, on 9 September 2011 at 5:00 pm and came into operation the following day. Regulations 5(4) and 5(5) took effect later, on 1 September 2013. The instrument is short and dense: a lifting-plan duty, an operator registration regime, the named roles on a lifting team, and a prohibition on anyone other than an approved crane contractor installing, repairing, altering or dismantling a crane.

▌  EFFECTIVE FROM 12 SEPTEMBER 2025  Circular MOM/OSHD/2025-05 carries the signature of SNG WEE KIAT, SILAS, Commissioner for Workplace Safety and Health, and is dated 29 August 2025. Its own terms say it takes effect from 12 September 2025 and supersedes MOM/OSHD/2020-01. So the Singapore regime has two dates worth remembering: 2011 for the duties, 2025 for the testing calendar.

▌  02  THE STATUTE BEHIND THE CRANE RULES

▌  ACT 7 OF 2006, IN FORCE SINCE 1 MARCH 2006  The Workplace Safety and Health Act 2006 began as Act 7 of 2006 and replaced the Factories Act as the general workplace statute. It places duties on occupiers, employers, principals and persons at work, and gives the Commissioner powers to register persons, approve contractors and prescribe requirements by regulation. The crane regulations are subsidiary legislation made under that Act, which is why a change to a testing interval can be made by circular rather than by amending the principal statute.

▌  THE GENERAL PROVISIONS REGULATIONS SET THE REGISTER  The Workplace Safety and Health (General Provisions) Regulations (G.N. S 134/2006) cover hoists and lifts, lifting gears, and lifting appliances and lifting machines, and they require a register of lifting gears to be kept. They were amended by S 517/2011 with effect from 10 September 2011 — the same day the crane regulations came into operation, so the two instruments have to be read together.

▌  RISK MANAGEMENT IS SEPARATELY DATED  The Workplace Safety and Health (Risk Management) Regulations 2006 (G.N. S 141/2006) have applied since 1 September 2006. A risk assessment is required for the work; records of it must be kept for at least three years; and the assessment must be reviewed at least once every three years, or sooner after an injury or a significant change to the work. Offences carry a fine of up to S$10,000 on a first conviction and up to S$20,000 or six months’ imprisonment, or both, on a subsequent one. These Regulations were amended by S 1019/2024 with effect from 1 January 2025.

▌  03  WHO MAY OPERATE, SLING AND SIGNAL

▌  REGISTERED OPERATORS FOR THE HEAVY MACHINES  Regulation 5 requires a mobile crane with a safe working load above five tonnes, or a tower crane, to be operated by a registered crane operator. Regulation 5A, inserted with effect from 7 January 2016 by S 4/2016, brings mobile cranes of five tonnes or less and lorry loaders into the same framework, which matters because the small lorry-mounted crane is the machine most often met on a Singapore road or site.

▌  THREE OTHER NAMED ROLES  Regulations 17, 18 and 19 give the lifting supervisor, the rigger and the signalman their own defined duties. A lifting team in Singapore is therefore a set of licensed or designated roles rather than a group of whoever is free, and the same logic runs through the whole instrument.

▌  A LIFTING PLAN IS NOT OPTIONAL  Regulation 4 requires the responsible person to establish and implement a lifting plan, and to keep it available for inspection. The plan is a document obligation that sits on the site, independent of whatever the crane manufacturer supplied, and it is the first thing a lifting operation is measured against.

▌  ONLY AN APPROVED CONTRACTOR TOUCHES THE CRANE  Regulation 20 restricts installation, repair, alteration and dismantling of a crane to approved crane contractors, and regulation 27 sets out the duties of the crane owner. Adding a crane brand or model to a contractor’s approved scope requires the manufacturer’s manual and at least one approved crane erector holding a brand-specific certificate; the Ministry of Manpower states that it takes about 30 working days to process and that there is no application fee.

▌  THE OPERATOR REGISTRATION ITSELF  A crane operator registration runs for two years and is renewable. The fee is S$20 and is not refundable; the applicant must be at least 21 years old; the certificate from an accredited training provider must have been obtained within six months before the application; and since 1 April 2016 applicants aged 50 and above must first pass a medical examination. Operating a truck-mounted mobile crane requires a Class 5 driving licence. The Ministry advises filing a renewal about 60 days before expiry. What an operator is registered to drive is therefore a specific, documented and time-limited entitlement — not a general skill.

▌  04  HOW OFTEN EQUIPMENT MUST BE TESTED

▌  TWELVE MONTHS IS NOW THE DEFAULT  Under the 2025 circular, while lifting equipment is in use, tower cranes, fixed cranes and other lifting machines are tested and examined every 12 months; mobile cranes every 12 months; lifting appliances every 12 months; and hoists every 12 months. Twelve months is the shape of the calendar unless a specific exception applies.

▌  THE SIX-MONTH EXCEPTIONS SURVIVE  Mobile cranes used for the carriage of persons remain on a 6-month cycle. Lifts remain on a 6-month cycle. Lifting gears used for the carriage of persons also remain at 6 months, while other lifting gears move to 12 months. The dividing line is people: gear that carries a person is still checked twice as often as gear that carries a load.

▌  HOISTS CAME DOWN FROM SIX MONTHS TO TWELVE  This single line is the clearest administrative saving in the circular. A hoist that was examined twice a year is now examined once, provided the site holds to the rest of the requirements. Where a contractor had built a six-monthly service visit into a maintenance contract, that contract now sits ahead of the legal minimum.

▌  THE OVERLOAD TEST MOVED, IT DID NOT DISAPPEAR  The circular removes the requirement to conduct an overload test after lifting equipment has been registered. The test still applies on first registration and on re-registration under a new owner, which is where a machine changes hands. The test load is normally 125 per cent of the safe working load: 110 per cent where the safe working load is above 100 tonnes but not more than 500 tonnes, and 100 per cent at 500 tonnes and above.

▌  WHO MAY SIGN THE RE-EXAMINATION  Periodic re-examination of lifting gears may now be carried out either by an authorised examiner or by a competent person appointed by the workplace occupier. The occupier keeps the option of appointing an authorised examiner, and inside sites with their own engineering bench the new route removes a scheduling dependency. The documentation duty does not move with it: the record stays with the occupier.

▌  05  THE NEWEST LAYER: STABILITY CONTROL AND TYPE APPROVAL

▌  NEW LORRY CRANES SINCE 1 JANUARY 2025  Circular MOM/OSHD/2024-07, dated 3 July 2024, requires newly registered lorry cranes to have an acceptable stability control system. The requirement covers lifting equipment classification codes 631, 632, 633, 638 and 639. The system must be fitted at the factory by the lorry crane manufacturer, or installed by that brand’s authorised agent. A system that only limits or stops movement according to the crane’s or the vehicle’s inclination is expressly not acceptable. Authorised examiners must verify that an acceptable system is installed when a new lorry crane is registered from 1 January 2025.

▌  THE SUPPORT GRANT RUNS TO 31 MARCH 2027  The Lorry Crane Stability Control System Grant was extended for another two years, to 31 March 2027. It reimburses up to 50 per cent of qualifying costs, capped at S$5,000 per lorry crane and S$20,000 per business entity. The crane must be 17 years old or younger and must fall under one of the lifting equipment codes above, and approval has to be obtained before the purchase is made — a grant applied for after the invoice is a grant refused.

▌  TOWER CRANES NEED TYPE APPROVAL  Suppliers and owners must obtain type approval for every tower crane model imported for use in Singapore, including used cranes not yet registered with the Ministry. One application covers one model. The published register of type-approved tower cranes notes, model by model, whether the machine is fitted with a data logger — the imported machine is assessed as a type before it is assessed as an installation.

▌  THE 2026 CIRCULAR LIST OPENED WITH LIFTING EQUIPMENT  MOM/OSHD/2026-02, Vertical Lifters in Conveyor Systems, is dated 16 March 2026 and is classified under Lifting Equipment. Lifting hardware that is not a crane is being looked at on the same schedule, which is worth knowing if a product sits anywhere near that boundary.

▌  06  WHAT IT MEANS WHEN YOU SPECIFY OR BUY

●  If your lorry crane is registered after 1 January 2025, can the manufacturer or its authorised agent document the stability control system as factory-fitted?

●  Does that system act on real load and stability data, or only on inclination — the one approach the Ministry has ruled out?

●  What interval is actually written into your maintenance plan: 12 months, or 6 because the equipment carries people?

●  Who will sign the periodic re-examination — an authorised examiner, or your own appointed competent person — and where will the records live?

●  Is an overload test still in the commissioning budget, and at what percentage of safe working load?

●  For a tower crane, has type approval been obtained for that specific model before the machine is shipped?

▌  07  WHAT TO WATCH

●  The Ministry of Manpower circular index is now the fastest signal. Anything filed under Lifting Equipment is worth reading the week it appears.

●  The stability control grant is time-limited: approval must precede purchase, and the scheme as published runs only to 31 March 2027.

●  Type approval is a pre-shipment step, not a site step. A model without it cannot be registered on arrival.

●  Occupier-appointed competent persons widen who may inspect, but the record-keeping duty stays with the occupier.

●  The direction of travel is consistent: fewer blanket periodic tests, more conditions attached to the equipment itself at the point of registration.
