发明名称 APPARATUS FOR PERFORMING A LOADING TEST IN AN ELEVATOR SYSTEM AND METHOD FOR PERFORMING SUCH A LOADING TEST
摘要 An apparatus and method for performing a load test in an elevator installation having an elevator car and a counterweight, which are connected to one another by a supporting device, and a drive brake for halting the elevator car during a downwards journey. The apparatus has a connecting element for fastening to the counterweight, an element with spring properties and a tensioning device for installation in the elevator installation. One point of the tensioning means is fixed to a stationary point of the elevator installation via the element with spring properties. Another point of the tensioning means is connected to the counterweight via the connecting element, wherein the tensioning device includes an actuating device with which to tension the element with spring properties in order to thereby exert a downwardly directed tensile stress on the counterweight.
