Tandem load bearing roller unit for industrial truck has roller carrier pivotable around point located below plane in which rotational axes of rollers are located

摘要

The tandem load bearing roller unit has two rollers(1,2) rotatably mounted on a carrier(3) which is pivotable around a point(B) located below a plane(6) in which the rotational axes(4,5) of the rollers are located. The distance between the rotational point of the roller carrier and the plane of the rollers' rotational axes is at least a quarter of the distance between the plane and floor or road surface(9).
