Single Girder Crane

TC/American Single Girder Cranes have a single patented track bridge beam supported by two end trucks that operate on parallel patented track runways. For special applications the crane system may be provided with multiple end trucks and runways. A variety of hoists or grabs or specially built lifting devices may be mounted on a carrier on the bridge beam to provide the lifting capacity and access needed for the application.
