All single cab RT cranes have the boom mounted right nextthe superstructure cab. While traveling with the boom down, this creates ablind spot on the entire right side of the crane. So I designed an RT Cranewith a low slung boom. This type of design is found on city cranes in Asia andEurope but are illegal to drive on roads in most states in the USA . So I have incorporatedthis concept into a strictly off road RT crane only. The low slung boom on myRT crane design allows for better visibility while traveling long distances onpipeline and high power line jobsites that are not accessible bymaintained paved roads.
