Benefits of technology

"The present invention is an improved railroad car for carrying motor vehicles on multiple levels. It includes a motor vehicle deck that is raised and lowered using a movable end portion. The deck is supported by counterbalance mechanisms that partially carry its weight. The deck is made of a lightweight composite sandwich construction with fiber reinforced plastic skins and a low density core. The deck has a shape that can accommodate motor vehicles of various heights. The lightweight deck is reinforced with fibers that extend in a transverse direction with respect to the deck. The technical effects of the invention include improved load carrying capacity, reduced weight of the movable end portion, and improved efficiency in raising and lowering the deck."

Problems solved by technology

The deck is heavy, and many operators have difficulty raising and lowering it with only a manually operated mechanical winch.

Embodiment Construction

[0032] Referring to the drawings, which form a part of the disclosure herein, FIGS. 1-4 show a multi-unit railroad freight car 10 that incorporates one preferred embodiment of the present invention. The freight car 10 includes two adjacent car units 12 and 14. Each respective car unit 12 and 14, in turn, includes a cargo well 20, a middle deck 16, and an upper deck 18 for selectively supporting and storing automobiles in a tri-level arrangement as shown in FIG. 2. The cargo well 20, the middle deck 16, and the upper deck 18 are sometimes referred to as the “A”, “B”, and “C” decks, respectively. Each deck 16, 18, and 20 preferably has a shape that provides ample strength for supporting motor vehicles, while providing sufficient space to accommodate motor vehicles of the various heights that the car is desired to carry.

[0033] As can be seen in FIGS. 2-3, the automobiles stored on the lowest level of the freight car 10 rest in the respective cargo well 20 of each car unit 12 and 14. I...

Abstract

A railroad car includes a body having a pair of side walls and at least a pair of parallel horizontal support beams extending along the side walls at substantially the same height. A movable end portion of a deck built as a lightweight composite structure may pivot with respect to the pair of support beams. A respective counterbalance apparatus is arranged between each of the pair of side walls and the movable deck portion at a location spaced apart from the pivot axis so as to provide a lifting force acting on the movable end portion to urge it to pivot upward about the pivot axis.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation of patent application Ser. No. 10 / 401,153, filed on Mar. 27, 2003, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION [0002] The present invention relates to railroad freight cars and in particular to a freight car for carrying motor vehicles on multiple levels. [0003] Railroad freight cars have long been used for transporting newly manufactured automobiles long distances from either the place of manufacture or a port of arrival to a place where the automobiles are reloaded onto trucks that deliver the automobiles to dealerships. In order for such railroad freight cars to be most economical it is desirable to carry a maximum number of motor vehicles on each railroad car, but it is also desired to be able to carry several different types of motor vehicles on each car and to be able to reconfigure the railroad freight car to carry such different types of vehicles without undue difficulty. [0004] U...
