The intent of the proposed standard is to provide improved uniformity of enclosed track underhung crane and monorail performance and encourage better communication between the manufacturer and the user. 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 for transporting personnel are not included in these specifications.
