Designation for monorail rack railways for overcoming extreme gradients in impassable terrain. The track consists of a square tube with a rack welded to the underside. The tube is supported on supports placed at intervals of several metres. As a result, monorack tracks have a relatively small footprint. They can overcome inclines of up to 100%. Horizontal and vertical curves are possible up to a radius of four metres. Therefore, they can be flexibly and individually adapted to the topography. Monorack tractors with diesel, petrol or electric drive are used as vehicles. They can carry loads of up to 250 kg.
A main field of application for monorack tracks is steep slope viticulture, where heavy loads have to be transported in topographically difficult locations. They serve as a means of transport for stakes, fertiliser and the grapes during the grape harvest or simply as a climbing aid for the winegrowers. A list of particularly exposed wine-growing areas, such as on the Moselle or in the Swiss canton of Valais, is included under the heading steepest vineyard. See also under Vineyard area.
