Two American National Standard Institute (ANSI) standards are now available from the Monorail Manufacturers Association, Inc. (MMA). The two standards, MH27.1 - 2009--Specifications for Patented Track Underhung Cranes and Monorail Systems, and MH27.2 - 2009--Specifications for Enclosed Track Underhung Cranes and Monorail Systems, are reaffirmations of the respective 2003 versions.
The first, MH27.1 - 2009--Specifications for Patented Track Underhung Cranes and Monorail Systems, assists manufacturers and users of underhung cranes and monorail systems. The standard Includes discussion of curves, switches, transfer devices, trolleys, lift and drop sections and associated equipment.
The second, MH27.2 - 2009--Specifications for Enclosed Track Underhung Cranes and Monorail Systems, was developed to improve uniformity of underhung crane and monorail performance and enhanced public safety. It represents suggested design practices and performance testing criteria for crane and monorail equipment, and developed with the sole intent of offering information to parties engaged in the manufacture, marketing, purchase, or use of crane and monorail equipment.
Both standards are now available from the Material Handling Industry of America (MHIA) at no cost at the MHIA Bookstore.
