20/5 TON HEAVY FABRICATION CRANE (#19322)

Project Description:
G.W. Becker, Inc. commissioned a new 20/5 ton electric overhead traveling crane for a manufacturer near Pittsburgh, Pennsylvania. This new EOT crane replaced an antiquated unit which was used in the customer’s rotor assembly department.  This 4-motion heavy service EOT crane was designed to be installed on an existing runway system of 58’-6” span and 34’ of lift. The hoist design included flux vector control specifically designed for a hoist without a mechanical load brake. The travel drives were designed with infinitely variable control and offer state of the art precision handling for extremely smooth control and  minimal maintenance.  The crane is operated by a 4-motion, 5-speed, ‘Belly Box’ control system.  This turnkey project included the new EOT crane and Electrical System installation to meet all current applicable CMAA, OSHA, ANSI/ASME, and NEC specifications.  To ensure the existing runway rail was adequate for use, a complete detailed Runway Rail Survey was performed.  This survey included span, straightness, elevation, rail-to-rail elevation and rail condition.
