Underhung Free Standing Bridge Crane Runway

Underhung free standing bridge crane runway has the best overall hook coverage

Braces to other support structures are not needed because the free standing design resists lateral and longitudinal forces on its own

Easiest system to expand

Allows for loads to be transferred between bays

Design Details
Underhung runway systems are designed to support the stand alone workstation bridge crane from the lower flange of the runway girder. These girders are commonly constructed from I or W flanged beams. Heavy duty patented track runways are available for high usage applications.  Patented track is fabricated with a hardened lower flange to resist wear. Both underhung runways and monorail spurs can use the same track; therefore, they can be interconnected as a cost effective means of transferring loads between building bays via transfer switches.

Multiple Cranes Sharing the Same Runway

Many times the most practical use of a runway is to utilize it to support more than one overhead bridge crane. Large and uneven loads can often be lifted when this is a requirement with two similar or different capacity cranes. Also one runway can support multiple bridge cranes and service various work cells located along the length of a bays runway. In this case for example you could have a 10 Ton runway system and have 5 five Ton overhead bridge cranes running on the 10 Ton runway by creating zones within each cell that cranes can travel in but not travel out of.

Sophisticated load summing controls are available that will even monitor the loads of multiple cranes operating on a common runway. This is particularly useful when you need the added flexibility of using many bridge cranes and to protect your runways from overloads that could lead to unsafe usage by the crane operators.

Beside electronic limiting devices please feel free to inquire of our application engineers about many different standard and custom mechanical devices that are available to allow many overhead bridge cranes to be used safely on a single runway.
