We stock 100 amp crane buzz bar power feed systems or; bus bars, buzzbar, busbar or buss bars as they are sometimes called.

The most common type is the 100 amp system complete with collector arms, three phase and earth. Each system comes with a set of collectors, handing brackets, joint clips and an end or center feed.

We also supply c-rail electrical festoon systems and Colton Electrical spare parts.


An average 5 tonne crane will need a 32 amp supply for example and the 100amp buzz bar power feed system does the job.
