Single Girder Overhead Travelling Cranes
Single girder overhead travelling cranes consist of lifting trolleys and end-carriages on a steel construction made of box beams or prefabricated steel beams (HEA, HEB, IPN, etc.). It is generally preferred for low lifting capacities and short bridge spans. Although it is an effective solution for low headroom between the ceilings and crane runway, it is advantageous in terms of initial investment cost. Generally, the main energy supply is provided by the bus-bar system, and the monorail lifting group power line is provided by the c profile or the moving cable channel. This type is preferred in many areas of the industry like: manufacturing, assembly lines, paint booths and over-the-counter material loading.
