Top Running Bridge Crane Types
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.
Push/pull or hand chain bridge cranes are the most cost effective solution of the top running bridge crane options. This bridge crane style is limited to a 5 ton capacity due to the man power it would take to lift and/or move a load of that weight. To learn more click here.

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.
Along with top running manual cranes, underhung single girder push cranes are the least expensive bridge cranes available and they have a better trolley end approach compared to a top running manual crane. The durable easy to operate manual bridge crane can be equipped with an electrical festoon wire or an air hose to provide power to your desired lifting apparatus. To learn more click here.
