Definitions
- the invention relates to a method for producing a running rail and a running rail for a running rail lifting device, which can be transferred by at least one lifting unit from a rest position to a working position.
- This lifting device comprises a running rail on which attack, for example, two lifting units and lifts the running rail from a rest position to a working position, so that, for example, repair and maintenance work on a vehicle can be performed.
- the rail In the rest position, the rail is located on the example Ground on or is arranged at ground level in a pit to a floor, so that in particular a vehicle can drive onto the running rail.
- the running rail comprises a load bearing, which for example has a flat running surface. Adjacent to the load receiving side are arranged outwardly aligned C-shaped profiles. These C-shaped profiles support on the one hand the load-receiving, and on the other hand, these form at the bottom outwardly freely projecting portion of the C-shaped profile a running surface for an axle jack, between two adjacently arranged rails
- this C-profile On the inside of this C-profile can be further provided a C-profile for stiffening.
- these C-profiles are held by transverse plates at a distance, which attack at the same time also on the underside of the load bearing.
- stiffening ribs are provided, which engage on the one hand on the underside of the load-bearing and on the other hand on the Querversteifungsele- ment.
- the invention is therefore based on the object to propose a method for producing a running rail and a running rail for a moving rail lift, which is inexpensive, has a high rigidity and yet allows lightweight construction.
- This object is achieved by a method for producing a running rail for a rail lifting device, in which a main body of the running rail or the Cross-sectional profile of the rail consisting of load bearing, side walls and receiving webs of a plate-shaped material is converted by several Abkant suitse in a final shape.
- at least one fold is provided between the load bearing and in each case a laterally adjacent thereto side wall as well as opposite to this fold each side cheek bounded by at least one further fold and formed a receiving web with a trained for load bearing driving surface.
- This method allows the main body of the running rail consists of a common plate-shaped material and due to the opposite folds between the running rail and the side wall and the side wall and the receiving web, the individual sections of the running rail as load, side cheeks and receiving webs are connected to each other throughout. As a result, the power flow lines can extend undisturbed along the entire cross section of the running rail, whereby a high rigidity is achieved. Due to the continuous connection via at least one fold between the side cheeks and the load bearing on the one hand and the side cheeks and the receiving webs on the other hand and the opposite Abkantraumen can be given a high stiffening against a deflection of the rail at a recorded load. In particular, the receiving webs act as traction belts against the deflection.
- the main body of the running rail is bent starting from a flat plate-shaped material, a metal sheet.
- sheets or metal sheets are preferably used with a plate thickness of, for example, 3, 4, 6, 8 or 10 mm, which are folded.
- these metal sheets may have a length of at least 3 m and are preferably adapted in length to the total length of the running rail, such as 8, 10 or 14 m.
- the fold over the entire length of the plate-shaped material or over the entire length of the rail allows or welded together from smaller sections.

- U-profiles may be provided, the base area between the two legs of the desired width of the tread of the load receiving, so that at least on each leg of the U-profile or each side cheek at least one fold to form the receiving web is required. Thereby, a further simplification in the production of the main body of the running rail can be made possible.
- a preferred embodiment of the method provides that the base body is folded at least four times from a flat plate-shaped material designed as a metal sheet.
- the side cheeks with respect to the load bearing and further the receiving webs are angled relative to the side cheeks, so that the main body is preferably formed after a kind of clip or the like.
- all bending angles are equal. As a result, a shorter set-up time on the canting press is necessary.
- the side cheeks for load bearing and the receiving webs are folded to the adjacent side cheeks at an angle between 60 ° to 90 °.
- a cross-sectional geometry can be achieved, which comes close to the previous weldments.
- a Abkantwinkel is provided between 70 ° and 80 °.
- the base body seen from one end side has an omega-like contour, wherein the load bearing and the Side cheeks are each formed in a straight line between the bending radii of the bends.

- a preferred embodiment of the running rail provides an angle of 90 ° or smaller, in particular from 70 ° to 80 °, between the load receiving means and the side cheek.
- a bending angle can be selected. If, for example, a limitation of the width of the running rail is not required, bending angles of 90 ° can be used. If the widest possible running surface of the load bearing is given at a predetermined width to the arrangement of the rails, angles between 70 ° and 80 ° are preferably provided, so that the free end of the running surface on the receiving web does not protrude beyond this transition region or the fold between side cheek and load bearing ,
