Cranes that are used in the construction industry are temporary structures which are mounted on a vehicle that is built for the specific purpose of carrying the crane.
Cranes that are controlled by a number of methods such as radio control, infrared control or a built in control station that uses a push button pendant or by an operator actually sitting inside of the cab of the crane.
