Abstract

Installations for trans-loading piece goods in the form of load units (3) such as containers, returnable vessels, semi-trailers or the like between road and railborne vehicles (2) comprise a single or multiple storey store (5, 6) for the load units (3) on one side of a single or multiple track railway line (1), a single or multiple lane roadway (9) on the other side of the store (5, 6) as well as lifting gear means (10, 11) for transferring the load units (3). In order to reduce the required floor area for simplifying the lifting gear means to be employed as well as accelerating the transfer, the store (5, 6) in such an installation is to be divided longitudinally into two parts with an operating space (7) accommodated between the store portions (5, 6) and having fixed to the four comers of the operating space (7) one load lifting gear means (11) each. The width of the operating space (7) corresponds at least to the length of the largest load unit which is to be transferred. In the operating space (7) a store lifting means (10) is movable which services the store parts. The load lifting gear means (11) have an operating radius of at least three quarters the length of the largest load unit and serve for loading and unloading the vehicles (2), in particular whilst travelling past at reduced velocity.

Claims

1. An apparatus for transloading load units including freight containers between road and rail borne vehicles, comprising:

a railway line;

railborne vehicles displaceable along said railway line;

a store for said load units disposed along one side of said railway line and including two compartmented store sections spaced apart along said railway line by at least a length corresponding to a largest load unit handled by said apparatus thereby defining an operating space between said sections, said operating space extending transversely to said railway line;

store lifting means displaceable along said operating space for transporting load units to and from compartments of said section and said operating space;

a roadway disposed alongside said store on a side thereof opposite said railway line, said operating space having four corners where said operating space adjacent said sections terminates at said railway line and said roadway; and

at each of said four corners of said operating space a respective load lifting device having an operating radius at least three quarters of a length of said largest load unit for loading and unloading said vehicle and storing said load in said store.

2. The apparatus defined in claim 1 wherein said store lifting means has a lifting structure including a spreader gripper for said load units movable in said operating space transversely to said railway line and said roadway.

3. The apparatus defined in claim 1 wherein each of said load lifting devices is a pivoting gripper having two swinging arms pivotally linked to one another, an outermost one of said arms being provided with a spreader gripper at a free end thereof.

4. The apparatus defined in claim 3 wherein a pivot is provided between an innermost arm of each pivoting gripper and a mounting thereof.

5. The apparatus defined in claim 4 wherein said innermost arm has a length dimensioned so that a linkage between the innermost and outermost arms remains outside a center of the nearest lane of said railway line and said roadway, respectively, in all operating positions of the respective load lifting device.

6. The apparatus defined in claim 1 wherein each of said load lifting devices includes a telescope gripper having a telescopically extendable horizontally and vertically pivotable carrier being bearing a spreader gripper at a free end thereof.

7. The apparatus defined in claim 1 wherein said load lifting devices are dimensioned and positioned for jointly moving a single load unit.

8. The apparatus defined in claim 1 further comprising between the railway line and the store, a horizontal longitudinal conveyor.

9. The apparatus defined in claim 1 wherein there is a mirror symmetrical arrangement of stores on both sides of the railway line.

10. The apparatus defined in claim 1 further comprising an enclosure for said store and said railway line.
