Motorized Underhung Bridge Cranes
Something unique to underhung cranes is their ability to be used in applications where the transfer of a loaded hoist and trolley from one beam to another beam is necessary. This can be accomplished through available transfer switches.
Utilizing Transfer Switches
With the use of these switches, ceiling-mounted workstation bridge cranes can be utilized to transfer a load from one underhung crane to another underhung crane (from bay to bay), from a bridge to a single spur or multiple monorail spurs, and to transfer an unloaded hoist to a hospital spur where it can be worked on and maintained without interfering with critical plant operations.
Hospital Spurs
If two hospital spurs are used one can support a maintained hoist while the other can be empty ready to accept an ailing hoisting unit. This use of hospital spurs is a great way to keep a plant “in production”. Click here for more information.
These underhung cranes are ruggedly designed CMAA class C duty units (lighter and heavier duty cranes are available) see CMAA crane classification information to determine which crane class best fits your needs.
Motorized bridge cranes commonly utilize electric chain hoists, underhung wire rope hoists,air hoists or balancers. All motorized overhead bridge cranes include either a tag line or c-track festoon system. Additional festoon systems are available when power or air supply is required for below the hook devices.
