LIFT specialist Otis was fined £400,000 last week after two men died when they fell 30 m down a lift shaft.
Michael Dawson and Daniel Digby were killed in February 2001 at Shirley Towers, a tower block in Southampton, when they fell against the lift doors.
The doors swung open 'like a cat flap' because of inadequate fixings on the lower rail of the opening.
Speaking after the case, safety inspector Antony Thompson said: 'These tragic deaths are a reminder for all those with responsibility for lifts that they should be properly maintained.
'It is important that maintenance is carried out on a regular and frequent basis and that lift landing entrances and lift doors are designed and constructed to withstand the anticipated use.
'The hearing today also highlights how important it is that the maintenance regime takes particular account of the door retaining system.'
