Abstract

There is described a device for removing a drawer-type hopper of a railroad car, the device comprising: a first support base positioned on a platform and a second support base supported on the railroad car; and a tackle fastened on the first support base; the tackle comprising a first hook associated to the drawer-type hopper, the first hook and the drawer-type hopper being moved linearly by the tackle in the opposite direction of the railroad car.

First claim

The invention claimed is:

1. A device for removing a drawer-type hopper from a railroad car, the device comprising:
a first support base having a bottom surface configured to be positioned on a horizontal platform;
a second support base having an end configured to be supported on the railroad car;
a base extension having a body that connects the first support base to the second support base at a fixed distance;
a drag mechanism fastenable to the drawer-type hopper;
an arm mechanism fastened to the first support base;
a linking mechanism coupling the drag mechanism to the arm mechanism, wherein operation of the arm mechanism drives the linking mechanism to translate the drag mechanism and the drawer-type hopper toward the first support base linearly along a horizontal plane; and
a supporting element fixed to the first support base and fastenable to the railroad car in an angular orientation relative to the horizontal plane.

2. The device as claimed in claim 1 , wherein the arm mechanism is positioned above the base extension and fastened on the first support base by a first hook, and wherein the drag mechanism comprises a second hook for fastening the drag mechanism to the drawer-type hopper.

3. The device as claimed in claim 2 , wherein the arm mechanism comprises a turnstile driven by an arm, the drag mechanism comprises a pulley, and the linking mechanism comprises a chain.

4. The device as claimed in claim 1 , wherein the supporting element has a length configured to maintain contact of the first base with the platform.

5. The device as claimed in claim 1 , wherein the body of the base extension includes a first extension portion and a second extension portion each extending in a horizontal direction, and a third extension portion extending in a vertical direction and connecting an end of the first extension to an end of the second extension.

6. The device as claimed in claim 5 , wherein the third extension portion is configured to engage a side of the platform.
