So that the overhead travelling crane travels steadily, smoothly and without great wear and tear, the crane track must be properly installed. Otherwise the overhead travelling crane will travel unsteadily and the wheels will wear out more rapidly.

The design and installation of the crane track must be taken into consideration upon construction of the building and planned together with the architects and structural engineers.

Observe the following points amongst others:

   The building supports and building beams or concrete supports or concrete girders as well as the brackets should be designed in such a way that the crane track can be welded onto them without difficulty.

   Only have welding work done by companies certified as per EN 1090 EXC-3.

   Monitor welded joints according to this standard.

   Design welded joints to at least quality class B of DIN EN ISO 5871.

   Clean the anchor plates (in the concrete brackets) or the steel brackets (to the building supports) prior to welding. They must be free of dirt, rust, scaling, paint, grease and oil.

   Cut the crane track joints at an angle of 45 degrees. Deburr the cut edges and clean. The gaps between the crane tracks should be as small as possible. The abutting crane track segments should not be misaligned laterally nor offset in height.

   For bolted crane tracks: firmly tighten all bolts with the correct tightening torque.

   Clean the crane tracks. They must be free of grease, oil, paint and dirt.

   Secure the crane track with suitable end stoppers.

   Provide the entire crane track with appropriate corrosion protection (e.g. paint)
