Comparison Table Of Common Anchor Bolt Types For Crane Rails

Sep 15, 2025

The anchor bolt is suitable for the steel structure foundation embedded parts, steel rail steel plate installation and fixation, the anchor bolt is generally Q235 steel. The screw steel (Q345) is strong, the thread of the nut is not easy to circle. For the bolt, the depth is 25 times its diameter, and then a 90 degree Angle with a length of about 120mm. If the bolt has a large diameter (such as 45mm), it is too deep to be buried deep enough to be able to do a large head on the end of the bolt end (although there is a requirement). Both the depth and the hook are designed to ensure the friction between the bolts and the foundation so that the bolts will not be removed.

 

rail fasteners

 

When installing crane rails, it is a critical step to use embedded bolts to fix the iron plate (such as crane rail clips, steel sole plate, etc.) structure. Bolts come in a variety of shapes, such as L-type, J-type, U-type, 9-type, Y-shaped bolts, etc. Their design differences are mainly to adapt to different force requirements, construction methods, structural conditions, and installation environments.

Note:

 

  • Pull-out resistance: refers to the ability of bolts to withstand external forces in the vertical direction, which directly affects the safety of the track during operation.

 

  • Installation flexibility: refers to the convenience of on-site construction, adjustment, and maintenance.

 

  • Spatial adaptability: refers to the adaptability in confined spaces (such as dense layout, multi-track installation, etc.);

 

  • Is it a standard part: whether there are current national/industry standards that can be directly selected, or non-standard parts need to be customized and designed, and produced.
