Inspection tests for an elevator without additional test weights

摘要

The invention allows inspection tests for an elevator without additional test weights. An empty elevator car and its counterweight are balanced by filling in weight pieces to the counter-weight. 100% load of the elevator car in regard to unbalance is configured by moving unused counterweight pieces inside the elevator car. Inspection tests requiring the 100% load in regard to unbalance are performed. 125% load of the elevator car is simulated with 50% load and 125% speed of the elevator car, such that substantially equal kinetic energy is achieved by utilizing overspeed of the elevator car instead of overload. Inspection tests requiring the 125% load are performed. A final counterweight is configured by moving its weight pieces from the elevator car to the counterweight. Inspection tests requiring the final counterweight are performed.
