The single girder crane system is the most popular type of industrial installation.
This steel system covers a rectangular (x-y) working area. Multiple girders are typically used when the system covers more than one working station. With multiple girders the complete system can either be dimensioned to handle the heaviest weight or the working areas can be separated with buffers.
This solution is very popular for several reasons such as the competitive pricing, high quality, fast deliveries and easy installation.
