ABSTRACT:
A loader having an elevated operator's platform mounted behind the cab of a truck. A ladder positioned to the side of the loader enables an operator to climb up to and down from the platform. The ladder includes a first standard fixed to the truck and/or loader, and a second standard carried by the first standard through interconnecting rungs normally spaced from the first standard outwardly of the acceptable travelling width of the truck. The outer standard and interconnecting rungs are pivotally connected to each other and to the inner standard whereby the outer standard can be pivoted upwardly against the inner standard to substantially reduce the width of the ladder to a position within the acceptable travelling width of the truck.
