How to select rail according to the circumstances ? Profile ? Quality ?

- The rail selection depends on the mounting type :

• for a discontinuous mounting, a high vertical inertia is necessary and leads to chose a "high profile" rail.
• for a continuous mounting, either low or high profile rail can be selected.
Note : in a channel, a low profile rail requires a shallower but wider channel.

- The head width must be chosen for each application, taking into account applicable standards and rules such as DIN 15070 and FEM 1.001.
The rail head width must cope with the crane wheel width, including a play of 5 to 20 mm according to dimensions.

- Most common steel grades are 70 and 90 (tensile strength equal to 690 and 880 N/mm˛ respectively). Higher tensile steels are also available on request.

- Standard rail length is 12 m. Lengths of 15 and 18 m, are also available, and reduce the amount of welding. Longer lengths can introduce logistical problems.

- Preference is given to the most frequently rolled profiles, but GANTREX can also provide you with the less common profiles and, when necessary, suggest alternatives.
