Abstract
An exemplary elevator system includes an elevator car. At least one guiderail is situated for guiding movement of the elevator car. A machine mount is supported by the guiderail near a top of the guiderail. A car stop is supported on the elevator car. The car stop is selectively moveable between a first position and a second position. In the first position the car stop allows the elevator car to travel to a maximum vertical position. In the second position the car stop is situated to contact the machine mount to prevent the elevator car from reaching the maximum vertical position.
