Abstract: A system for transporting a crane includes a crane which has a boom which is connected to a base, the base has a front end and an opposite rear end. A coupler is connected between a tractor and the front end of the base. A dolly is connected to the rear end of the base. In an embodiment the dolly includes a rear cradle which is shaped and dimensioned to receive and support the boom during transporting. In another embodiment the coupler includes a front cradle which is shaped and dimensioned to receive and support the boom during transporting.

Abstract: A system for transporting and operating a crane includes a front adapter which connects to the front end of the base of the crane, and a rear adapter which connects to the rear end of the base of the crane A coupler pivotally connects to the front adapter, and also connects to the tractor. A dolly pivotally connects to the rear adapter. In a transportational configuration the crane is suspended above the support surface between the coupler and the dolly. In an operational configuration the coupler and the dolly remain connected to their respective adapters, with their weight fully supported by the ground. This allows the crane to be used with no reduction to the manufacturer's rated capabilities. In accordance with another embodiment, the dolly includes a rear cradle which is shaped and dimensioned to receive and support the boom during transportation.

Abstract: Apparatus for steering a boom support vehicle includes a boom support vehicle which has a front section which is rotatably connected at a pivot to a rear section. The one side of the rear end of the front section is connected to the same side of the front end of the rear section by a variable length mechanism. Steering is effected by changing the length of the variable length mechanism thereby causing the rear section to rotate about the pivot with respect to the front section.
