Wall-Travelling Jib Cranes

This type of crane has a single bridge girder that supports the hoist and trolley mechanism, and it travels on top of the runway beams. The runway beams are typically elevated on the columns of the building. A top-running single girder crane is commonly used for lifting lighter to medium loads, generally up to 20 tons and with a span of up to 60 feet. This design is efficient in terms of cost and space, as it requires less material in construction and can operate in spaces with limited headroom.

Similar to the single girder version but features two bridge girders for supporting the trolley and hoist. This design allows it to handle heavier loads and longer spans, often more than 60 feet and is capable of carrying very heavy loads exceeding 100 tons. Double girder top running cranes are typically used in heavy manufacturing, where they can also support attachments like walkways and cabs due to their robust structure.

Also known as an underhung crane, this design features a single girder that is supported by the roof structure rather than by elevated runway beams. The trolley and hoist run underneath the girder, and the crane itself can move along runway beams that are mounted directly to the ceiling. This setup maximises the available headroom beneath the crane, making it ideal for facilities with limited floor space. Under-running single girder cranes are typically used for light to medium loads, up to about 10 tons, and are common in precision manufacturing, assembly operations, and areas where floor space must remain clear.
