Analysis of a Case of Insufficient Travel of Elevator Counterweight Guidance
Cutting and hanging steel wire ropes to adjust the buffering distance of counterweights is a common maintenance operation for traction driven elevators.However,if the length of the suspension steel wire rope is excessively cut,it will result in insufficient guide stroke of the counterweight.Due to being a supervisory inspection item,this item is easily overlooked in regular inspections.Through a regular inspection case,the idea of discovering insufficient counterweight guidance travel and typical steps for inspection and verification were introduced.By analyzing the causes of the problem,suggestions for maintenance and inspection before and after changing the relevant space dimensions were proposed,such as cutting and hanging steel wire ropes for elevators and installing elevator air conditioning,etc.
