ABSTRACT:
The invention relates to a cable or pipeline trolley (2) for travelling along a carrier rail, comprising at least one chassis (1) and a carrier device (10) for cables or pipelines, in addition to a central plate (9) that connects the carrier device (10) to the chassis (1). Known cable or pipeline trolleys of this type are sensitive to high winds and are frequently derailed from the guides as a result of the large wind-exposure area. The aim of the invention is to develop a cable or pipeline trolley so that it is more operationally secure and the chassis can run more reliably along the carrier rail even when exposed to high winds or other stress. To achieve this, at least two rectangular cavities and two triangular cavities (6, 7) are positioned within the outer boundary of the central plate (9), said cavities being symmetrical in relation to the central axis of the central plate and being separated by a strut.
