This Part 6 of EN 1993 provides design rules for the structural design of runway beams and other crane supporting structures. The provisions given in Part 6 supplement, modify of supersede the equivalent provisions given in EN 1993-1. It covers overhead crane runways inside buildings and outdoor crane runways, including runways for a) overhead travelling cranes, either: supported on top of the runway beams; underslung below the runway beams; b) monorail hoist blocks.

However, crane rails not mounted on steel structures, and rails for other purposes, are not covered. Cranes and all other moving parts are excluded. Provisions for cranes are given in ÖNORM EN 13001-1 and ÖNORM EN 13001-2. For seismic design, see ÖNORM EN 1998. For resistant to fire, reference should be made to ÖNORM EN 1993-1-2.
