<p>The guide rail (1, 2) for a supply trolley is profiled and forms the rolling path for the trolley. Further hooks (8, 9, 10) are provided on the upper surface, transverse to the rail length. The hooks can be made from pipe. There are two parallel rails, made of hollow tube. The tubes on the upper surface form the transverse parts to keep the profiles parallel. At the ends of the rails there are attachments to enable the rails to be joined together. The rails are for use in building work, with cable operation.</p> |
