How heavy is the crane rail

Sep 29, 2025

The weight of crane rails is typically calculated as "weight per meter," as different models have significantly different cross-sectional sizes. According to the Chinese standard GB/T 11264-2016, common crane rail models include QU70, QU80, QU100, and QU120. Their approximate theoretical weights are as follows:

 

  • QU70: Approximately 52.8 kg/m

 

  • QU80: Approximately 63.7 kg/m

 

  • QU100: Approximately 88.9 kg/m

 

  • QU120: Approximately 118 kg/m

 

Rail Type SIZE(mm) theoretical weight
height bottom width head width waist depth
Crane rail QU70 120 120 70 28 52.8
QU80 130 130 80 32 63.69
QU100 150 150 100 38 88.96
QU120 170 170 120 44 118.1

 

It can be observed that larger model numbers correspond to thicker rail heads and webs, resulting in a higher weight per meter. For example, a standard 12-meter length of QU120 rail has a total weight of nearly 1.4 tons. This makes it highly suitable for high-load applications like ultra-heavy-duty port cranes or gantry cranes in metallurgical plants.

Compared to standard railway heavy rails (e.g., 60 kg/m), crane rails generally have a taller overall section and a wider head. They are designed to withstand concentrated loads from frequent starting, stopping, and high wheel pressures. Selection must consider the crane's wheel load, span, and operational frequency to ensure track stability and safety.

 

Classification Height(mm) Head (mm) Bottom (mm) Thick(mm) Weight (kg/m)
Heavy Rail 38 KG/M 134 68 114 13 38.733
43 KG/M 140 70 114 14.5 44.653
45 KG/M 145 67 126 14.5 45.546
50 KG/M 152 70 132 15.5 51.514
60 KG/M 176 73 150 16.5 60.64
