Abstract
Load cells on antirotation dowel pins or load mounts indicate brake reaction forces in the disk brake of an elevator. Vertical load cells on bending load cell indicate vertical brake reaction loads on a rail . A table indicating the load of an empty car at each of the landings served by the car permits subtracting load components relating to ropes, chains and cables to provide a live load indication prior to brake release; this may be used to determine if the load exceeds the maximum permissible load for the car.
