ABSTRACT:
A floor relay contact 15 is connected between an elevator cage load detecting device 14 and a memory circuit 16. Just before the cage 7 reaches a desired floor the relay contact is closed to apply the output of the load detecting device 14 to a traction motor current control circuit 12 via the memory. This minimizes any acceleration-deceleration bumps and eliminates any vertical gap between the accessed floor sill and the stopped position of the cage when passengers exit before the cage comes to a complete halt.
