Bridge Cranes

Bridge Cranes are typically designed for applications that require higher lifting capacities and or larger bridge spans. This style of crane comes in one of two design options; Top Running or Underhung. A Top Running Bridge Crane travels the top flange of a runway via guide rail known as Square Rail or ASCE Rail. An Underhung Bridge Crane travels the bottom flange of a runway. Although a bridge crane is less flexible and more perplex to use, the runway design is a good solution for facilities that have low headroom.

Bridge Cranes come in many different shapes and sizes. With options for either Manual, Geared or Motorized each application has different needs with opportunities to protect your budget by selecting the correct material handling solution.

Top Running Bridge Cranes

Designed more for the heavier lifting in the range of 20 tons or more, top running cranes are less flexible and more perplex to use. Top running crane runways are good for facilities that have low headroom, because the system moves above the runway which allows for extra headroom. A rail is installed on top of the runway beams, and the wheels ride on the rail rather than directly on the runway beams.

Underhung Bridge Cranes

Generally a lot lighter than a top running system, under hung crane runways allows for more versatility usability. Underhung runways can be ceiling mounted because of being dramatically lighter. Also they have the ability to run side-by-side without interfering with one another. Another mechanical advantage that under hung crane systems have is that they can be interlocked together. By locking the adjacent ends of two cranes together an operator can transfer the load from one system to another. They can also interlock with monorails to allow for the transferring of material along a fixed path.
