ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention uses alternatively, a retrofittable or new-floor—tube mounted—fabricated load securing anchor mounted to railcar beams, cross bearers, and bolsters. The anchor operates in conjunction with load securing straps arranged to apply securing loads on cargoes through a combination of straps, preferably straps in conjunction with resilient load securing pads.
2. Description of Related Art
The most common load securement method for railcars handling cargo such as large heavy items is to load the items on a railcar floor and secure the items with a variety of chains or straps typically using hooks to anchor the securement member (the chain or strap) and toggle and adjustment devices for tensioning.
Often the hooks are attached to the chain or strap and are anchored to eyes, or bars in pockets, or other structural members on the railcar. Additionally, specialized anchors or hooks having generally T-shaped members on the strap or chain fit into corresponding recesses in a railcar floor or, in the case of a flatcar, occasionally into a recessed pocket whereby the head of the “T” bears against a specialized anchor piece in the pocket.
Other load securement practices in the rail industry in the prior art included numerous other mechanical load securement methods such as: blocks, chocks, and specialized mechanical locks often varying depending on a specialized load.
The anchors shown here are preferably mounted in 4 to 10 (or more) anchors-per-car sets. The anchors are preferably mounted in pockets or recesses formed in line with current bulkhead floor track. If there is no floor track, then the anchors can be mounted anywhere along the wall, preferably above a major structural floor member.
SUMMARY OF THE INVENTION
A plurality of anchors are arrayed in association with a railcar floor, particularly being affixed to the railcar frame members that support the floor including longitudinal beams, longitudinal beams in association with riser and cross bearer members, and railcar bolsters.
Each anchor consists of a flat plate or channel with two to four (or more) elongated holes to which hooks engage. Preferably these are hooks mounted at the ends of adjustable tensioning straps. The anchors have flat plate or channel forms mounted flush with the car floor so that “slip-sheet” loads do not engage them. The anchors are also designed so that the holes will permit load securement bulkheads to engage the holes if a car is so equipped.
Typically, an array of floor anchors associated with each end and an additional pair associated with the car transverse center line—typically a box car door location—can be used to secure a variety of loads in combination with various railcar arrangements. These include using a plurality of vertically aligned foam pads or other resilient members acting against railcar ends and bulkheads, using opposed straps bearing against one another, particularly at the door position, or using strap tensioning against car ends in the absence of bulkheads. It is also advantageous to support coils on resilient, friction increasing horizontal pads.
The retrofittable embodiment uses height adjustable mounting to permit perfectly flush mounting in imperfectly level floors, or on distorted car frame members. The new-floor, tube mounted embodiment uses a short portion from a tube, mounted vertically, as the connecting member between the top plate and car frame.
