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. |
