The Bridge Crane is a specialised type of overhead crane that is mostly used in heavy-duty industrial settings.
Basic Structure of a Bridge Crane All Bridge Cranes have the same basic structure. A crane cross girder supports a moving trolley with a hoist attached. The crane cross girder can be a single girder or a double girder – with varying advantages. Single girders are typically less expensive and use simpler trolley systems, whereas the double girder allows for greater hook height. The entire Bridge Crane is supported by runway beams, allowing it to travel along the length of a factory. Types of Bridge Crane |

There are two distinct types of Bridge Crane that you may come across, top running bridge cranes and under running bridge cranes.
For top running bridge cranes the Bridge Crane structure rides on top of runway beams. This system allows greater loads to be lifted and is a more efficient use of headroom. |

Under running bridge cranes (underhung cranes), on the other hand, ride along the bottom of the runway beams.
These beams are usually attached to the ceiling, reducing the amount of floor space taken up by the crane. However underhung cranes have a lower capacity, only lifting around 10 – 15 tons efficiently.
Advantages of Bridge Cranes Bridge Cranes are widely used in heavy-duty industrial plants including train construction and cement processing plants. While they are generally more expensive than, for example mobile gantry cranes, they are an excellent long term investment and have some significant advantages: • Greater control over the load, allowing very gentle load placement. • Capable of lifting heavy loads safely and with ease • Allow very precise hook placement • Keeps the factory floor clear of obstructions Of course the cost may be prohibitive and in some circumstances a gantry crane may meet your needs just as well.
