Rubber tired, swivel mounted wheel designed to support free end of truck crane booms during over-road trips permits faster, safer and more economical moves because it eliminates stresses and strains that are usually placed on machine and its rigging when boom is carried flat; boom head rides at fixed distance from ground and is not affected by up and down movement of machine, and low position of boom head prevents motorists from following dangerous inclination to duck under boom in passing.
Wheel gives crane boom mobility
