That comes as no surprise, too many people 'tweak' things without the requisite knowledge. One of the worst lift 'accidents' I was involved with down the line was an interfloor hydraulic scissor platform lift in a retail food store, the manager to save time had modified it to continually cycle between the limit switches, with staff expected to load/unload with it whilst moving, one of the 'saturday lads' (school children over 14 earning a small wage) slipped and had his head separated from his body. And it seems the lift industry needs to sort out its act too, though the 'engineer' would probably have been fired if he'd locked out the lift? https://www.insidehousing.co.uk/news...old-girl-59772
