How are crane rails designated?

By the prefix 'CR' followed by the nominal head width in mm (e.g., CR 50, CR 80).

What is the standard length in which crane rails are supplied?

Usually supplied in lengths of 10 m and 13 m, unless specified otherwise by the purchaser.

Does this standard cover the material grade for crane rails?

No, it primarily covers dimensions and sectional properties. The material specification is typically agreed upon between the manufacturer and purchaser or governed by structural steel codes.

Practical Notes

Crane rails are designated by the letters 'CR' followed by the width of the rail head in mm (e.g., CR 80 has an 80mm head width).

Always ensure the crane wheel profile matches the chosen crane rail head profile to minimize wear and prevent derailment.

Sectional properties provided in Table 1 (Area, Ixx, Iyy) must be added to the properties of the supporting gantry girder if composite action is considered, though they are often conservatively ignored in bending resistance calculation.
