Claims

[Scope of Claim for Utility Model Registration] (1) A pair of hooks are provided on the top surface of the door body, and each door body is provided with a locking means that can close the openings of these hooks only when the door body is suspended. A horizontal beam guided by rollers at both ends in the same door groove is suspended by an elevating means, and a pair of left and right operating shafts are pivotally supported on this beam perpendicular to the longitudinal direction of the beam. A lifting device for a corner drop gate, in which a locking pin is fixed via an arm, and a counterweight rotatably supported on the operating shaft is fixed so as to be changeable to a desired angle. (2) A utility model registration claim in which the angle of the counterweight can be changed to a desired angle by the meshing of meshing teeth provided on the operating shaft with meshing teeth of a boss integral with the counterweight. A lifting device for a corner drop gate as described in Scope 1. (3) A lower elevating rod in which the detachment preventing means has a lower end portion protruding downward from the lower end surface of the door body; A lifting device for a corner drop gate as set forth in claim 1, which is a utility model registered and comprises a double-armed ram and an upper lifting rod that is pivotally connected to the other end of the ram and closes the opening of the hook.
