Air-Powered technology is a common tool used for heavy lifting in the mining, building and construction industries. The Serco's AB dock leveler utilizes this technology to provide proven, long-term, reliable service on the loading dock every day.

Compared to mechanical dock levelers, the Serco's air bag dock leveler is safer and far easier to operate. To raise, simply push a button. There’s no back-wrenching pulling of chains, walking down the deck and, best of all, no springs or hold-down to repair or replace.
