Abstract
810,319. Lifts. MONTGOMERY ELEVATOR CO. April 30, 1956, No. 13225/56. Class 78 (3). [Also in Group XXXVII] A microswitch mounted on a lift cage is operable to cut-out the lift motors in the event of an overload in the cage, and another switch may be provided to give prior warning of an approaching overload. As shown, a switch 37, mounted on a beam 9 of a lift cage roof, is operated by movement of a lever 29 about its pivot 28, this movement being caused by a pin 40 attached to a plate 14 which can move laterally against the action of a spring 25 and to which plate the lift-supporting cables 17 are attached through springs 18. The plate 14 is connected to the beam 9 by links 16 joining bearing blocks 13, 15 on the beam and on the plate respectively, and the spring 25 is set by means of an adjustable stop 23 so that the plate 14 does not move until the load in the cage exceeds a predetermined maximum. Two switches may be operated by the lever 29, the first to operate giving an audible or visible warning and the second cutting out the lift motors.
