The required frequency depends on the equipment category, and Singapore's Ministry of Manpower (MOM) updated these rules as recently as September 2025. As it stands: hoists and lifts must be tested and examined by an Authorised Examiner at least once every 12 months (changed from every 6 months); lifting machines such as fixed cranes and derricks are examined every 12 months, with mobile cranes dropping to every 6 months if they're used to lift personnel; lifting platforms are inspected every 6 months for personnel-carrying units or 12 months for material-only units; lifting appliances are inspected every 12 months; and lifting gear (chains, slings, shackles) is inspected every 12 months, or every 6 months for personnel-carrying lifting cages. Separately, periodic overload testing — previously a recurring requirement — was removed for most equipment after initial registration, and now applies mainly at first registration, re-registration, or after major repair.
Why the Rules Just Changed
In a circular issued on 29 August 2025 and taking effect on 12 September 2025, MOM reviewed test and examination requirements for statutory lifting equipment, benchmarking against practices in the United Kingdom, United States, Australia, and Japan. The stated goal was to reduce unnecessary cost and equipment fatigue for businesses without weakening safety outcomes — specifically by extending the hoist inspection interval from six months to twelve, removing periodic overload testing after a piece of equipment's first registration, and giving workplace occupiers more flexibility in who can carry out periodic re-examinations of lifting gear. For any business running cranes, hoists, or lifting gear on a maintenance calendar set before September 2025, it's worth checking whether that calendar is still accurate — some of these changes reduce the required frequency, which matters for planning and cost, but doesn't reduce the under safety expectations.
Lifting Equipment Inspection Frequency, by Category
Singapore's lifting equipment framework sorts equipment into statutory categories, each with its own inspection cycle, all conducted by a MOM-approved Authorised Examiner (AE) — a Professional Engineer specifically approved for this work:
- Lifts and Hoists (LH): every 12 months (previously every 6 months, changed September 2025)
- Lifting Machines (LM) — fixed cranes, derricks, and similar equipment: every 12 months
- Mobile cranes and piling machines (also classified under LM): every 12 months generally, or every 6 months if the mobile crane is used to lift personnel
- Lifting Platforms (LP): every 6 months for platforms that carry personnel, every 12 months for material-only platforms
- Lifting Appliances (LA): every 12 months
- Lifting Gear (LG) — slings, shackles, chains, hooks: every 12 months generally, or every 6 months for lifting cages used to carry personnel
All categories are also subject to examination before first use, after relocation to a new site, and after a major repair or re-assembly of key components such as wire rope or boom sections — regardless of where the equipment sits in its regular cycle.
Who's Allowed to Carry Out the Inspection
Every statutory examination still needs to be signed off by an Authorised Examiner — MOM's list of approved examiners is specific to equipment classification, so an AE approved for tower cranes isn't automatically approved for lifting gear, for instance. One genuine change from September 2025: for periodic re-examinations of lifting gear specifically, workplace occupiers can now appoint either an AE or another competent person, rather than being limited to AEs alone. AEs remain mandatory for the higher-stakes moments regardless of equipment type — first use, and after any major repair or modification.
The Statutory Minimum Isn't the Same as a Maintenance Plan
It's worth being clear about what these inspection cycles actually cover. An AE's statutory examination confirms the equipment meets the legal minimum to keep operating — it isn't the same thing as an ongoing maintenance programme that catches wear between those checkpoints. A wire rope showing early fraying, a brake that's started responding unevenly, or a hook nearing its wear tolerance can all develop well within a 12-month window, long before the next statutory inspection is due. This is generally the gap that scheduled preventive maintenance is meant to close — many crane owners in Singapore run this alongside the statutory cycle rather than instead of it. Providers such as Jenmon offer routine inspection and maintenance support structured around exactly this gap, though the statutory AE examination itself always has to be carried out by an approved examiner regardless of who handles day-to-day servicing.
What Non-Compliance Actually Looks Like
Lifting equipment that isn't inspected on schedule isn't just a paperwork problem. Registration can lapse, affecting insurance standing and potentially preventing a piece of equipment from being used on-site until it's rectified; MOM can also issue directions or take enforcement action if it finds equipment operating without valid certification. For businesses managing a fleet of mixed equipment types across different cycles, the more common failure mode isn't outright non-compliance — it's simply losing track of which unit is due for which type of inspection, which is exactly the kind of thing worth building into an equipment register rather than re on memory.
The Bottom Line
There's no single answer to "how often," because Singapore's rules are deliberately calibrated by equipment type and risk — hoists and general lifting appliances now sit at a 12-month cycle, lifting gear and platforms carrying personnel stay at 6 months, and mobile cranes shift between the two depending on use. The September 2025 changes eased some of these intervals, but they didn't remove the under obligation to track and document every cycle accurately. For any business running lifting equipment in Singapore, the practical takeaway is less about memorising the table above and more about having a system — digital or otherwise — that flags each unit's next due date before it becomes a compliance gap.
