A load detector device for an elevator which detects the load of an elevator cage having rod-shaped anchoring members connected to ropes which suspend the cage. Each anchoring member having an associated elastic support member which elastically supports the anchoring member to an anchoring plate which is axially translatable. Activator members are provided, each surrounding an anchoring member and bearing at one end thereof on an annular seat fitted on the anchoring member, to extend axially translatably through the anchoring plate. Displacement of the ends of the activator members with respect to the anchoring plate is detected by a displacement detector thus facilitating determination of the cage load.
