Alerts & Learnings Under sized runway beam end stops Two High Potential incidents were recorded in 2022 due to the fall of lifting trolleys from their runway beams. Similar incidents have also occurred in previous years: The lifting trolley beam (weight 172 kg) together with the chain block (weight 64 kg) slid from the runway beam and fell on the deck, 4.7 m below. No persons injured.The monorail beam trolley (84Kg) overran the endstop and fell (5m). No person injured. Why it happened?: For all cases, the runway beam end-stops failed to prevent the hoist trolleys running off the end of the beam: a) the end-stops were undersized for the beam / trolley width, or b) the manual hoist trolleys were oversized for the beam used. Beam stoppers are usually designed for defined type of trolleys (Ref. manufacturer guide). When changing the type of trolley, there is a risk that the end-stop is not correctly sized for the trolley in use.
