Abstract
The invention relates to a chassis () for a cable or pipeline trolley (), for traveling along a carrier rail, the chassis including at least one pair of carrier rollers () having a horizontal axis of rotation and at least one pair of guide rollers () having a vertical axis of rotation. The disadvantage of known chassis of this type is that they jolt at uneven sections of the carrier rail and a significant supply of replacement parts is required for repairs. The aim of the invention is to develop a chassis with improved driving characteristics, whilst at the same time reducing production and inventory costs. To achieve this, the carrier rollers () and guide rollers () are essentially arranged symmetrically to a vertical axis.
