Abstract

Railcar ramp systems and related methods are disclosed. An example railcar ramp system includes a carriage slidably coupled to a platform via a track guide. A ramp mover assembly is pivotally coupled to the carriage. The ramp mover assembly positionable between a stored position and an active position. In the active position, the ramp mover to enable movement of the carriage in a lateral direction along the track guide.

First claim

What is claimed is:

1 . A railcar ramp system comprising:
a carriage slidably coupled to a platform via a track guide; and a ramp mover assembly pivotally coupled to the carriage, the ramp mover assembly positionable between a stored position and an active position, in the active position, the ramp mover assembly to enable movement of the carriage in a lateral direction along the track guide.

2 . The railcar ramp system of claim 1 , wherein the carriage is to slide horizontally relative to the platform.

3 . The railcar ramp system of claim 1 , further including a leveler coupled to the carriage.

4 . The railcar ramp system of claim 1 , wherein the ramp mover assembly includes a first frame attached to the carriage and a second frame pivotally coupled to the first frame via a hinge, the hinge to enable the second frame to pivot relative to the first frame or the carriage.

5 . The railcar ramp system of claim 4 , wherein the hinge includes a first barrel fixed to the first frame, a second barrel fixed to the second frame, and a pin to couple the first barrel and the second barrel.

6 . The railcar ramp system of claim 5 , wherein the pin defines a pivot axis of the hinge.

7 . A railcar ramp system comprising:
a carriage slidably coupled to a platform via a track guide; and a control panel pivotally coupled to the carriage, the control panel positionable between a non-deflected position and a deflected position, in the deflected position, the control panel to pivot away from the platform in a rotational direction.

8 . The railcar ramp system of claim 7 , wherein the control panel is rotatable about a hinge axis relative to the platform.

9 . The railcar ramp system of claim 7 , wherein the control panel includes a first post, a second post and a panel coupling the first post and the second post.

10 . The railcar ramp system of claim 9 , wherein a first end of the first post is pivotally coupled to the carriage via a first hinge and a second end of the second post is pivotally coupled to the carriage via a second hinge.

11 . The railcar ramp system of claim 10 , wherein the first hinge includes a first knuckle coupled to the first end of the first post, a second knuckle coupled to the carriage, and a first pin to pivotally couple the first knuckle and the second knuckle, the first pin defining a pivot axis of the first hinge.

12 . The railcar ramp system of claim 11 , wherein the second hinge includes a third knuckle coupled to the first end of the second post, a fourth knuckle coupled to the carriage, and a second pin to pivotally couple the third knuckle and the fourth knuckle, the second pin defining a pivot axis of the second hinge.

13 . The railcar ramp system of claim 7 , further including a biasing system to bias the control panel to an upright orientation.

14 . The railcar ramp system of claim 13 , wherein the biasing system includes a first spring assembly and a second spring assembly, the first and second spring assemblies including springs to bias the control panel toward the upright orientation.

15 . The railcar ramp system of claim 14 , wherein the biasing system to enable the control panel to deflect away from the platform when an impact force is applied to the control panel.

16 . A control panel comprising:
a control panel; a mounting plate to couple the control panel to a platform; and a deflection system including a pivot hinge to pivotally couple the control panel and the platform.

17 . The control panel of claim 16 , wherein the deflection system includes a biasing assembly to bias the control panel to an upright position.

18 . The control panel of claim 17 , wherein the biasing assembly includes a first spring assembly and a second spring assembly.

19 . The control panel of claim 18 , wherein the first spring assembly includes a first screw, a first spring, a first nut, and a first mounting fastener, the first mounting fasteners to attach to the mounting plate and receive a first end of the first screw, the first screw to receive the first spring, and the first nut to couple to a second end of the first spring to retain the first spring coupled to the first screw, wherein a support plate of the control panel is positioned between the first nut and the first mounting fastener.

20 . The control panel of claim 16 , wherein the deflection system further enables slidable movement of the control panel in a first lateral direction and a second lateral direction relative to the platform, and wherein the pivot hinge includes a first knuckle and a second knuckle coupled via a pin, the first knuckle coupled to the mounting plate and the second knuckle coupled to a frame of the control panel, the pivot hinge to enable pivotal movement of the control panel relative to the mounting plate and slidable movement of the control panel relative to the platform.
