Abstract

A crane, particularly a rubber-wheel container crane including a frame which has, on opposite sides of its lower part, main beam structures at both ends of which, i.e. in the lower corners of the crane, there are in each particular case two successive rubber wheels or wheel arrangements through which the crane is supported to its moving carrier. These wheels are, in each particular case, supported to the main beam structure rigidly and in an unsuspended manner.

Claims

1. A crane, comprising:

a frame which has, on opposite sides of a lower part thereof, main beam structures at both ends of which, there are in each particular case two successive rubber wheels or wheel arrangements through which the crane is supported to a moving carrier thereof,

wherein the wheels in each corner of the crane are, in each particular case, supported to the main beam structure rigidly and in an unsuspended manner, and wherein the main beam structure of the crane comprises several subassemblies attached to each other with detachable frame joints, and wherein the distances between the frame joints are dimensioned to determine the main dimensions of the subassemblies, these main dimensions being smaller than the inner dimensions of the transportation space.

2. The crane according to claim 1, wherein said at least two successive wheels or wheel arrangements are, in each particular case, supported to the main beam structure by a rigid auxiliary frame.

3. The crane according to claim 1, wherein said at least two successive wheels or wheel arrangements are supported directly to the main beam structure.

4. The crane according to claim 1, wherein all wheels are supported to the main beam structures in such a way that they rotate substantially 90°

around vertical support axles thereof.

5. The crane according to claim 1, wherein the inner wheels are drive wheels.

6. The crane according to claim 1, wherein the load-carrying capacity of the outermost wheels is greater than the load-carrying capacity of the inner wheels.

7. The crane according to claim 1, wherein the outermost wheels are arranged higher relative to the level of movement than the inner wheels.

8. The crane according to claim 1, wherein the outermost wheels are arranged to be lifted higher relative to the level of movement than the inner wheels.

9. The crane according to claim 1, wherein the main beam structures form, in each particular case, a beam structure in the shape of an A or an inverted U as seen from the side.

10. The crane according to claim 1, wherein at least one of the subassemblies comprises the lower part of a leg beam of the frame structure, and wheels supported to the leg beam of the frame structure rigidly and in an unsuspended manner, and wherein the upper end of the leg beam has a detachable frame joint to attach the leg beam to the upper part of the frame structure for operation and to detach the leg beam for transportation.

11. A rubber-wheel container crane comprising:

a frame which has, on opposite sides of a lower part thereof, main beam structures at both ends of which, in the lower corners of the crane, there are in each particular case two successive rubber wheels or wheel arrangements through which the crane is supported to a moving carrier thereof,

wherein the wheels in each corner of the crane are, in each particular case, supported to the main beam structure rigidly and in an unsuspended manner, and wherein the main beam structure of the crane comprises several subassemblies attached to each other with detachable flanged joints, and wherein the distances between the frame joints are dimensioned to determine the main dimensions of the subassemblies, these main dimensions being smaller than the inner dimensions of the transportation container space.
