Built to articulate and self-level, SafeRack’s SAS gangways are designed to accommodate varying heights of vehicles with a typrical working range of 40° below hortizonal and 45° above horizontal. And they’re designed to last, too. With a one-piece stair design, welds are reduced and failures are virtually eliminated. Still, despite being extremely rugged, our SAS gangways are easy to use, as the spring counterbalance requires minimal effort. On top of that, the self-adjusting stair gangways can easily be retrofitted to replace your old, unsafe gangways. All models come standard with rubber bumpers for vehicle protection, machine-quality pivot points and a hot-dipped galvanized steel base tread.
