Shannahan Crane & Hoist

Double Girder Underhung Bridge Crane

Double Girder Underhung Cranes are ideal for applications where additional headroom under the runways is necessary.  Runways can be integrated with the building for a ceiling mounted or suspended runway.  Notched bridge beams provide a low headroom design utilizing the depth of the runway.  Double Girder Underhung cranes are capable of larger spans and higher capacities.  NEMA rated components make for an ease of maintenance as well as modular designed components such as brakes, controls and motors.

  • Available for CMAA Class A, Class B, Class C, and Class D.
  • Capable of capacities up to 25 tons and spans up to 100 feet or more.

  • This field is for validation purposes and should be left unchanged.
