<p>A suspension system for an overhead contact wire for electric traction vehicles has a carrier cable with its mid point connected to a support and having each of its ends connected to respective clamps. The clamps comprise a jaw assembly including a generally cylindrical housing fitted with inwardly directed teeth on its inside surface, the housing receiving an angularly adjustable link member which includes an angle-determining portion provided with complementary teeth and interfitting with the teeth of the housing. The link member may be moved axially into and out from the toothed housing so that it may be set in different angular positions therein, thereby changing the location of a point fastened to the end of the carrier cable relative to the contact wire. The carrier cable tends to pull the link member against an axial abutment, thus locking it in a selected angular position,and by suitably selecting the angular position, the contact wire may be suspended vertically below the clamping means in order to avoid interfering with vehicle pantographs, even where the contact wire is following a curved path thereby causing the plane defined by the carrier cable and the contact wire to be sloping at an angle from the vertical.</p> |
