NOTICE FOR DOVER ELEVATOR GEARLESS OWNERS IN CANADA WITH 2:1 ROPING RATIO

Important safety notice for Canadian owners of Turnbull-Dover gearless 2:1 roping ratio elevators. The article discusses incidents where counterweights have separated from their respective ropes or the counterweight sheave has detached and fallen into the elevator cab. The problem is attributed to worn bearings on the idler sheave, which eventually leads to the tearing and separation of brackets holding it in place. The article emphasizes the need for diligence in inspecting these sheaves and promptly shutting down any elevator making unusual noise. It mentions that the Technical Standard and Safety Authority (TSSA) is reviewing the issue, and a Director's Order to repair the situation is likely to be issued. Owners are advised to contact their elevator contractors to determine if their equipment is affected, as repairs may entail a one-week shutdown and a cost of approximately $20,000 per elevator.
