Crane rail is a particular type of steel rail that is designed to support hoisting devices -- i.e., cranes -- along a pair of tracks. They are commonly used in industrial yards and manufacturing plants. The biggest difference between crane rail and other types of rail is its shape and the amount of weight it's designed to support. Crane rail is notably shorter than train rail and usually has a thicker travel track. A100 crane rail is a specific type of rail, which is designed to meet specific international industry standards.

To be internationally certified, A100 crane rail must be able to support 67.9kg. per yard of track, or 74.3kg per meter. This weight requirement falls roughly in the middle of certified track requirements. The highest certification, A150, must be able to support nearly 137kg. per yard, while the lightest certification must be able to support just 2021kg. per yard.
Head width describes the diameter of track at the peak, where the crane travels. This is perhaps the single most important factor when selecting a device to travel on the tracks because the machine's wheels should fit snugly and completely over the rail. A100 track's standard size is 100mm, or 3.94 inches.
Height, Base Width and Web
The height, base width and web are less relevant numbers than the head width. Nevertheless, there are international standards for these three figures as well. A100 crane rail has a 95mm (3.74 inch) height, a 200mm (7.87 inch) base width and a 60mm (2.36 inch) web, which describes the width of the track just below the head.
