Top Running Bridge Cranes

Under Running Bridge Cranes

Top Running Overhead Bridge Cranes vs Under Running ‘Under Hung’ Overhead Bridge Cranes

Your application may require a single girder top running crane, a single girder under running crane (also known as an ‘Under Hung Bridge Crane’), a double girder top running crane or a double girder under running crane.

Top Running Single Girder Bridge Cranes

Provided in CMAA Class A (standby or infrequent service), Class B (light service), Class C (moderate service), Class D (heavy service).

Typical capacities range from 3 ton up to 35 ton with spans up to 90 feet. (Higher capacities and spans are available). Single girder bridge cranes are built from standard I-Beams or Wide Flange Beams, although but custom fabricated monobox, patented track or truss construction can be required. This is determined by an application specialist.

Single Girder Under Running Bridge Cranes

Provided in CMAA Class A, Class B, Class C, and Class D.

Under running bridge cranes are also widely known as underhung bridge cranes or underslung bridge cranes. These cranes can be provided in spans exceeding 80 feet and capacities up to 30 tons. Typically spans do not exceed 65 feet with capacities not exceeding more than 15 tons.

This solution is widely used when applications require loads to be transferred to a parallel bay. This is possible via the under hung bridge crane’s design which allows it to interlock and transfer the load to a monorail and then onto another crane, loading dock or area of your choosing. If your application requires the transferring of loads, your crane will most likely be required to use patented track. Although some applications allow for wide flange beams or use of standard I-beams.

Double Girder Top Running Bridge Cranes

Double Girder Under Running Bridge Cranes

Double Girder Bridge Cranes

Built for the highest hook height, highest capacity and longest spans, Double Girder Bridge Cranes get it done!

Double Girder Top Running Bridge Cranes

Provided in CMAA Class A (standby or infrequent service), Class B (light service), Class C (moderate service), Class D (heavy service).

Capacities range from 3 ton up to 500 ton with spans of up to 200 feet or more. Depending on your applications requirements, double girder bridge cranes can be built from standard I-Beams, Wide Flange Beams or require custom fabricated Box Girder construction. This is determined by an application specialist.

Double Girder Under Running Bridge Cranes

Provided in CMAA Class A, Class B, Class C, and Class D.

Under running double girder bridge cranes are ideal for tight headroom clearances. This design allows for a Nested Trolley or Nested Hoist which allows for increased hook height by mounting in-between the two girders. These cranes can be provided in spans exceeding 100 feet and capacities range from 1/2 ton to 25 tons.
