Two standards – one for enclosed track and the other for patented track underhung cranes and monorail systems – have been released by the American National Standards Institute (ANSI). The announcement was made by The Monorail Manufacturers Association (MMA) an affiliate of Material Handling Industry of America (www.mhia.org.)

The MMA "sponsored these standards in the interest of improved uniformity of patented track and enclosed track underhung crane and monorail performance and enhanced public safety," says the group. It also pointed out that the standards should be looked at as "guides rather than rigid specifications."
