Single Girder Cranes
Standard, 2-runway, single girder Trambeam cranes are cataloged for rated loads to 10 tons and for spans to 100 feet. Multiple runway cranes are also available.
These cranes may be hand propelled, hand racked or motor driven depending on travel distance, frequency of operation, span, elevation and rated load. When used with electric hoists or when motor driven, they are equipped with an electrification system.
Service classifications for cranes are described as ANSI MH 27.1 Specification for Underhung Cranes and Monorail Systems. Cataloged cranes will generally meet the service classification of the hoist and carrier selected to operate on the crane and the requirements of the comparable ANSI MH 27.1 service classification.
