Although it is not common double girder top running bridge cranes can be provided with underrunning trolley hoists.
Double girder top running bridge cranes are typically used in heavy industrial applications ranging from aerospace, steel fabrication, steel processing, steel mills, repair of heavy construction/industrial equipment, defense, railroad construction, energy, plastics, ship construction, heavy chemical, heavy electrical, mining, scrap handling, refuse handling, oil refining to name a few. In addition these can be provided for special environments such as molten metal handling, explosion proof or spark resistant, clean room, nuclear or food processing.
Double girder bridge cranes can be provided with many options. Some available options include dual hoist, radio remote control, independent traveling pushbutton station, anti-collision, limits for travel on hoist, bridge or trolley motion, variable frequency control with up to 1000:1 speed control, service and full man platforms, air conditioned controls, cab control, dummy cab, visual and auditory signals, and weight readout. Other specialized options can be provided such as powered bottom block, closed loop variable frequency drive control, magnets, cable reels, stacker mast, and stacker mast for boats.
Advantages of Double Girder Top Running Cranes
