Abstract
A method for creating a temporary safety space within an elevator hoistway by preventing upward or downward movement of a car or counterweight along guide rails. The method includes the steps of providing engagement members on the guide rails and extending support struts from the car or counterweight to either side of a guide blade of the guide rail, whereby upward or downward movement of the car or counterweight along the guide rail is prevented when the extended support struts bear against the engagement members.
