<p>The cable way is for use as a toy or for gymnastic purposes. It has two upright masts with upper transverse beams, and connecting parallel cables. The distance between the cables is so dimensioned, that the travelling crane trolleys do not touch, when meeting. Return travel of each trolley is effected by a driving cable, which connects both trolleys via a horizontally positioned return pulley. Instead of a large return pulley, each transverse beam may carry an additional deflexion pulley.</p> |
