High web crane rail
These rail profiles have especially been designed to make the foundation absorb heavy loads via the rails. Available in various lengths and steel grades, see specifications.
Tooling possibilities: sawing to measure, drilling, milling, bending and preserving.

The admitted wheel load in the rail table is based on the steel grade of the rail, the rail system applied and the normal service factor as defined in the DIN 15070. When optimizing these factors the maximum wheel load can be increased by approximately 35%.
