At G.W. Becker, Inc. our double girder cranes are designed and manufactured to either CMAA Specification #70 or AIST Technical Report #6.  In addition, they meet current ANSI, NEC, and OSHA specifications.

Double girder overhead cranes are most frequently applied in capacities over 10 tons and spans greater than 60 ft.

Ordinary girder type construction for light duty, short span bridges are standard rolled steel sections.  Alternatively, welded plate box girders are available, but standard on heavier duty, higher capacity and longer spans.

The typical advantages of double girder overhead cranes are:

  • Higher hook lift, since the hook can be pulled up between the main girders
  • Extremely rigid box girder construction and durable trolley design are well suited for heavy service applications
  • They are also highly suitable where the crane needs to be fitted with walkways, cabs, magnet cable reels or other special equipment.

The typical disadvantages of double girder overhead cranes are:

  • Higher initial cost
  • Heavier dead weight
  • Reduced hook approaches

Based upon your lifting requirement and budget, we can offer either economical packaged equipment or custom engineered overhead lifting equipment.  We are experts in applying the correct engineered equipment for your company’s specific application.
