A double-girder semi-gantry crane consists of a crane mechanism that includes a trolley, hoist, and bridge. Unlike a gantry crane, this setup doesn’t require runway support on both sides. Instead, one end carriage of a semi-gantry crane travels on the regular gantry rail, while the opposite end-carriage travels on a rail mounted on the ground or at a lower elevation. Many call them a combination of an EOT and a gantry crane that can be installed indoors and outdoors.

Our innovatively crafted semi-gantry cranes are particularly useful to give an extensive cover of the floor space. They can be installed below a pre-existing EOT to enhance work efficiency without interfering with its operations. Applications such as a tool room where part utilisation of the bay is required or at outdoor sites where a gantry rail can be installed on the side of an existing structure make excellent use of ElectroMech semi-gantry cranes.

A double-girder semi-gantry crane is used for heavy applications. It has a capacity range starting from (3.2t to 500t) SWL. It has a robust structure with several inbuilt features. A double-girder semi-gantry crane is useful when the factory support structure is available on one side.

Our Team of experts can design and engineer double-girder semi-gantry crane solutions as per customer requirements and can make them more productive and efficient with additional components.
