摘要:
The invention relates to a method for producing a track (14) for a track lifting device (11) and to a track (14) which can be transferred from an idle position into a working position (12) by at least one lifting unit (15), wherein a main body (27) of the track (14) is made from a plate-shaped material, wherein the main body (27) is transferred by a plurality of chamfering steps of the plate-shaped material into an end shape in which, between a load pick-up (16) and a respective side flange (31) adjoining same laterally, a chamfer (28, 29) is formed having a chamfer direction of the chamfers directed toward each other, and each side flange (31) formed in this way is delimited by at least one further chamfer (32, 33) having a chamfer direction opposite to the chamfer direction of the chamfers (28, 29). A receiving web (34) is formed with a travel surface (36) directed toward the running surface (17) of the load pick-up (16).
