Design of Monorail Systems
Tomas Orihuela, P.E.
Overview
This course provides guidance
for the design of a monorail beam system. The design concept presented is for a
manually-driven trolley hoist on a single beam or girder based primarily on the
Crane Manufacturers Association of America (CMAA) Specification No. 74.
Deflection limitations, fatigue, and operational safety will also be discussed.
Two case studies are presented to show the effectiveness of a well-planned
overhead material handling system.
When this course has been
completed, the reader will be familiar with the basic design of a single girder
monorail system for bottom-running manual trolley hoists.
The student must take a
multiple-choice quiz consisting of twenty questions at the end of this course
to earn PDH credits.
Specific Knowledge or Skill Attained
This course teaches the following specific knowledge and
skills:
