Eurocode 3 - Design of steel structures - Part 6: Crane supporting structures

EN 1993-6 provides rules for structural design of crane supporting structures.(2) EN 1993-6 is applicable to crane supporting structures, especially to indoor and outdoor overhead crane runway beams, of: a) overhead travelling cranes, either:- top-mounted cranes;- underslung cranes;b) monorail hoist blocks. EN 1993-6 does not apply to the tracks and suspensions of light crane systems conforming with EN 16851, see Figure 1.1. Additional rules are given for ancillary runway items including crane rails, structural end stops, surge connectors and surge girders and for runway supporting structures. EN 1993-6 does not apply to cranes and all other moving parts. Unless specifically stated, EN 1990, EN 1991 and the EN 1993-1 series apply.The design methods given in EN 1993-6 are applicable if- the execution quality and tolerances are as specified in EN 1090-2, and;- the construction materials and products used are as specified in the relevant parts of EN 1993, or in the relevant material and product specifications.- Following interfaces between hoisting device and its supporting structure are assumed:a) the top of crane rail for top-mounted cranes;b) the top of flange on which the crane or hoist block operates for underslung cranes and monorail hoist blocks;c) the support points as shown in Figure 1.1 for light crane systems.
