Abstract
A mobile crane includes a chassis having first connection features located on a rear end thereof. An outrigger includes second connection features for mating with the first connection features. A tag axle assembly includes third connection features for mating with the first connection features. The first connection features may accept either the second connection features or the third connection features, so that the mobile crane may be selectively configured for highway travel and selectively configured for working operation. One or more axles of the mobile crane may be elevated when the tag axle assembly is connected to the first connection feature. Further, a wheeled boom dolly may be employed to share weight with the chassis when the mobile crane is travelling. By allowing the outrigger to be replaced with the tag axle assembly, the present invention allows the mobile crane to be conveniently configured for road travel in a manner suitable to the axle spacing and axle weight restrictions of the local area.
