According to the common practice in the case of loading yards havingwharves of the above-mentioned kind the wharves are used only when goods are to be transported to and from such vehicles in which the wagon-bridge is positioned at a differentheight compared to the-plane'of the loading yardrOn the contrary, vehicles having the wagon-bridge at thesame height as the plane of the loading yard are driven close to the front side of the loading yard and are being charged without the aid of wharves. Due to the provision of the supporting and running rails of the wharves on the front side of-the loading yard, deformations of the rails have often occurred, caused by ramminginto said side, resulting in requirement for time consuming straightening or mounting works. Also, deformation of the rails has not always been observed by the displacement of the wharves along the loading yard resulting in damage of the rollers of the wharves. I

The object of the present invention is to eliminate these drawbacks by the provision of a loading yard designed to permit protection of the rails so that ramming into these is prevented and also allow the rails to be protected from falling goods. The invention also permits the journals of the rails to be more easily kept free of ice and snow.

To accomplish this object, the invention is substantially characterized in that the loading yard has a longitudinal member, positioned above the rails, and defining a stop edge preventing the vehicles from being driven so close to the loading yard that the rails are being deformed.

The invention will be described in greater detail hereafter with reference to the accompanying drawings in which:

FIG. 1 is a partially sectional side view illustrating the loading yard according to the invention and a wharf.

provided thereon, and

FIG. 2 shows a sectional side view of another embodiment of a loading yard according to the invention.

The Wharf 1 comprises a vertical frame 2, the upper ends of the side sections thereof being bent backwardly and defining arms 3, extending over a loading yard. Pivots 4 connect the arms 3 to the rear ends of two forwardly extending arms 5, which at the inner side of the front ends thereof are provided with a bar 6 onto which the plate 7 of the wharf 1 is placed. The plate 7 has reinforcing beams 8 on the underside thereof and two horizontal pins 9 are provided on the beams, the pins extending under each arm and Contacting their undersides. Furthermore, the plate 7 is connected to the frame 2 through a hydraulic device adapted to keep the same in different angular positions. The hydraulic device comprises a hydraulic cylinder 10 pivotally mounted on the frame 2 and a piston 11 pivotally mounted on one of the reinforcing beams 8. The hydraulic device is actuated by means of an operating device. designed in a manner known per se and thus not described in more detail. Further. the frame 2 has a shield 12 to protect the hydraulic device from being LII rammed into when the plate 7 is setin an idle position. In order to keep the wharf l suspended on the yard and to displaceably mount the same along the front side of the yard the frame'2 is provided with flanges I3, 14, I5 for a number of rollers running on two stationary rails l6, 17. These are positionedhorizontally along the front side of the yard, the upper rail 16 being designed in such a manner that it defines a horizontal journal for rollers 18 and a vertical journal for rollers 19. Preferably, the rail 16 comprises a U-profile 16a positioned with the legs directed downwardly so that the inner side of the outer leg forms the vertical journal and further comprises an L-profile 16b mounted on the U-profile,

. fining a vertical journal for rollers 20. This suspension permits thewharf l to besuspended in a steady manner on the yard and easilymovable along the same.

According to the invention, the loading yard is designed toprevent deformation of the

rails

16, 17 when vehicles are driven close to the same for charging. and discharging goods. For this purpose the loading yard 21 has, according to the embodiment illustrated in FIG.v 1, transverse beams 22 extending forwardly over the rails 16', 17. A profile 23 -is provided on the front end of'the beams,'said profile extending long the whole length of the yard with the front side 23a thereof positioned in or in front of a vertical plane running through the outermost edge of the rail 16. This means that the front side 23a of the profile defines a stop edge preventing vehicles from being driven so close to the loading yard that the wagon-bridge or other part thereof abuts the rails 16, I7 and deforms the same.

In the yard embodiment shown in FIG. 1, preferably the

rails

16, 17 are provided on foot beams 24 extending downwardly from the transverse beams 22 and held in position with the aid of supporting beams 25 mounted on posts 26 for the transverse beams 22. F urther, the yard has a plate (not shown) supported by the transverse beams 22 and defining the driving plane of the yard.

FIG. 2 illustrates another embodiment of the yard in which the loading yard 27 is cast concrete. According to this embodiment, a U-profile -28 is mounted on the front side of the yard so that the waist part 28a thereof lies in the same plane and the legs 28b thereof extend into the concrete. To hold the U-profile in a stable manner, the same is also provided with a number of stay wires 29 embedded in the mass of concrete. The rail 16 is mounted on the lower end of the waist part 28a of the U-profile and extends outside of the front side of the yard. The rail 17 is held to the yard partly by bolts 30 extending into the mass of concrete and partly by stay wires 31 running to the rail 16 and provided on the U-profile 16a.

According to the invention, a square profile 32 is provided on the web part 28a of the U-profile 28, said square profile running along the yard and having such a width that the front side 32a thereof is positioned in the same or in front of the vertical plane running through the outermost side of the rail 16. This means that the profile 32 constitutes a stop edge for vehicles being driven close to the loading yard 27 for the purpose of charging and discharging goods.

In the loading yards shown in the drawings, the part 22a and the

profiles

23 and 32, respectively, define shields to prevent ramming into the rails l6, 17. In addition, the risk of ice and snow forming on the journals of the rails is reduced The illustrated embodiments of loading yards can be varied within the scope of the following claims. Furthermore, the invention is not being limited to the loading yard illustrated but the loading yard may be designed in different appropriate ways in order to span the distance between a vehicle and the plane of the loading yard.
