An elevator arrangement (1) and method for temporarily transporting overloaded loads in an elevator arrangement (1), wherein the car (2) and the counterweight (4) are engaged by one or more traction sheaves (12) The suspension rope (6) is connected to each other, the traction wheel is driven by the motor (10), and the traction force between the suspension rope (6) and the traction wheel (12) is increased independently of the counterweight (4) for the expected overload operate.
Description
technical field The present invention relates to an elevator and a method of temporarily operating an elevator outside normal rated operating conditions to enable transport of heavy overloaded loads from one floor to another. Background technique In order to maximize installation efficiency while maintaining cost effectiveness, elevators are typically designed and manufactured to operate at predetermined rated operating conditions (eg, rated load and speed) to meet the transportation requirements specified by the particular equipment. However, there are temporary and uncommon situations where it would be useful to enable building owners to operate elevators outside of rated operating conditions, for example, for transporting heavy items, such as power transformers, which would otherwise be Items can overload the elevator. Typically, a solution has been used in which the mass of the counterweight is increased in proportion to the expected overload of the car in order to ma...
