Enclosed Track Underhung Cranes and Monorail Systems
This standard applies to underhung cranes whose end trucks operate on the internal flange of a runway using enclosed track section; and to trolleys (carriers) operating on single-track monorail systems, including all curves, switches, transfer devices, lift and drop sections, and associated equipment. Systems used for transporting personnel require special considerations and are not included in these specifications. This standard does not apply to underhung cranes whose end trucks operate on the lower flange of a patented-track runway section. Refer to ANSI MH27.1-2016, Patented Track Underhung Cranes and Monorail Systems for patented-track runway sections and patented-track monorail systems.
