11.5.2 Selection of Runway

The choice of runway depends on the location, task requirements, and the type of lifting appliance used. This should be given careful consideration as subsequent alteration and/or relocation may be very costly or prove impossible.

The choice of a runway of standard constructional section or special track will to a large degree also be influenced by the application and chosen lifting appliance.

The resulting loads imposed on the building structure or foundations are almost always in addition to those for which the building has been designed. A theoretical check should therefore be made by a structural engineer or other suitably qualified person and written confirmation of the adequacy obtained and kept with the lifting equipment records. (See section 1 1.A4 APPENDIX 4 - STRUCTURES and 1.A6 APPENDIX 6 - PRINCIPLES FOR THE SELECTION AND USE OF LIFTING APPLIANCES)

The loads imposed on the support points will comprise the load to be lifted, any slings and equipment used to attach the load to the lifting appliance, the weight of the appliance and trolley, a proportion of the runway and fixings self-weight and a dynamic allowance defined in the applicable design standard.
