FIGS. 1-4 schematically depict systems, methods, apparatuses for disconnecting a cable 100 from a railcar 102. In some instances, as depicted in FIG. 1, the railcar 102 may be a center beam railcar or the like with a box beam top member. Any type of railcar may be used. The railcar 102 may be loaded with various types of cargo 104. The size and shape of the cargo 104 may vary. In some instances, in order to ensure that the cargo 104 is secured within the railcar 102, one or more cables 100 (or other types of cargo straps, wires, bands, etc.) may be used. For example, the cargo 104 may be placed within the railcar 102, and the one or more cables 100 may be fastened about the railcar 102 to ensure that the cargo 104 is secured within the railcar 102.
In some instances, the cables 100 may be fastened to the top 106 of the railcar 102. For example, as depicted in FIG. 2, the top 106 of the railcar 102 may include a slot 108, such as a keyhole slot 110, configured to receive an end 112 of one of the cables 100. Any type of fastening device may be used to secure to the cable 100 to the top 106 of the railcar 102. For example, the cable 100 may include a chain linked end 114 or the like that may be positioned within the keyhole slot 110. The cable 100 may be tightened about the railcar 102 by a rachtet or the like. For example, an opposite end of the cable 100 may be fastened to the bottom of the railcar 100.
Once the railcar 102 reaches its destination, the cargo 104 may be removed from the railcar 102 by removing the cables 100. In this manner, the chain linked end 114 of the cable 100 should be removed from the keyhole slot 110 at the top 106 of the railcar 102. Access to the top 106 of the railcar 102, however, can be difficult and/or dangerous. Accordingly, as depicted in FIG. 3, a railcar tool 116 is disclosed herein for disconnecting the cable 100 from the railcar 102. The railcar tool 116 may enable a user to disconnect the cable 100 at the top 106 of the railcar 102 from the ground level. That is, the railcar tool 116 does not require that the user climb atop the railcar 102 in order to disconnect the cable 100 from the railcar 102.
In an embodiment, the railcar tool 116 may include an elongated body 118. The elongated body 118 may include a first end 120 and a second end 122. The elongate body 118 may be a pole-like structure. A handle portion 124 may be disposed about the first end 120 of the elongated body 118. In some instances, the handle portion 124 may include a grip or other type of graspable surface. In this manner, the handle portion 124 may be configured to be grasped by a user. The handle portion 124 enables the user to maneuver the railcar tool 116.
The railcar tool 116 also may include an engagement member 126 disposed about the second end 122 of the elongated body 118. The engagement member 126 may be configured to engage the cable 100. In some instances, the engagement member may be V-shaped 128. The engagement member 126 may be any size, shape, and/or configuration suitable to engage the cable 100. For example, the engagement member 126 may be T-shaped, L-shaped, C-shaped, U-shaped, etc. The V-shaped engagement member 128 may be guided by a user along the cable 100. The user may press the V-shaped engagement member 128 against the cable 100 to remove the chain linked end 114 of the cable 100 from the keyhole slot 110 at the top 106 of the railcar 102. For example, the user may manipulate the V-shaped engagement member 128 to apply a force to the chain linked end 114 of the cable 100. The length of the elongated body 118 may enable the user, standing at ground level, to position and press the V-shaped engagement member 128 against the cable 100 to remove the chain linked end 114 of the cable 100 from the keyhole slot 110 at the top 106 of the railcar 102.
In some instances, the user may twist the elongated body 118 while applying the force in order to disengage the chain linked end 114 of the cable 100 from the keyhole slot 110 at the top 106 of the railcar 102. For example, the railcar tool 116 may include a crossbar 130 attached to the elongated body 118. The crossbar 130 may be grasped by the user. The crossbar 130 may enable the user to apply a twisting motion (torque) to the V-shaped engagement member 128. The crossbar 130 may be substantially transverse to the elongated body 118. The crossbar 130 may extend out from one or both sides of the elongated body 118. In some instances, multiple crossbars 130 may be used. The crossbar 130 may be located nearer the first end 120 of the elongated body 118 than the second end 122 of the elongated body 118. In this manner, the crossbar 130 may be spaced apart from the handle portion 124 so as to enable the user to grasp the handle portion 124 with one hand and the crossbar 130 with the other. The crossbar 130 may include a grip or other type of graspable surface. The crossbar 130 may be detachable from the elongated body 118. For example, the elongated body 118 may include an aperture that the crossbar 130 is slid through.
The handle portion 124 may also be detachable from the elongated body 118. Similarly, the engagement member 126 may be detachable from the elongated body 118. In some instances, the elongated body 118 may be telescopic. In this manner, the railcar tool 116 may be disassembled and reassembled as need. In other instances, the railcar tool 116 may be a unitary structure. For example, the elongated body 118 and the engagement member 126 may be welded together or the like. Any means may be used to assemble the various components of the railcar tool 116.
As depicted in FIG. 4, the user may grasp the handle portion 124 with one hand and the crossbar 130 with the other hand. The user may then guide the V-shaped engagement member 128 along the cable 100. Once the V-shaped engagement member 128 is positioned adjacent to the fastened chain linked end 114 of the cable 100, the user may apply a force to the cable 100 by pressing the V-shaped engagement member 128 against the cable 100 to disengage the chain linked end 114 from the keyhole slot 110. The user also may apply a twisting motion using the crossbar 130 to further assist in disengaging the chain linked end 114 from the keyhole slot 110. In this manner, the user, standing on the ground, may disengage the cable 100 from the railcar 102.
