In five days across three countries, four crane events pointed at the same blind spot: the machine’s own state. A counterweight being installed on a tower crane in Bucheon, South Korea, swung and killed one worker; a crane parked on uneven ground in Penang, Malaysia, toppled onto a nursing home and injured an 84-year-old resident; in Shenzhen, a site manager said a 50-tonne-class truck crane was tipped over by a sub-250 kg cable tray because the outriggers had never been extended — contradicting the owner’s earlier “overweight” account, which our own 10 October article had repeated and which we correct here; and Chinese regulators kept listing dead rated-capacity and moment limiters as major accident hazards. This article turns that cluster into a working guide: what crane stability monitoring actually watches, what OSHA 1926.1402 and 1926.1416(e)(5)(i), EU Regulation 2023/1230 and China’s GB 45067-2024 require, four field faults that make a stable machine tip, a seven-point buyer’s checklist, and what these devices cannot do.
