Hemco's Self Adjusting Stair gangway (SAS) provides safe access where there are numerous height differences in tanker trucks and railcars being serviced from the same elevated walkway. Standard models are available in 3 tread, 4 tread, 5 tread and 6 tread, each having the ability to reach out as far from the elevated walkway as needed. Longer stringers are available, but may require hydraulic assistance for ease of folding up and down.
After the Safety Securing Latch is released, a slight push out on the top of the gangways will drop the treads as they remain horizontal to meet the desired top of the truck at any height either above or below the elevated walkway.
The internal balance mechanisms keep the gangway in perfect balance for effortless operation throughout the full range. To retract, simply pull on the pull chain located on the right side of the gangway. The balance mechanisms will gently raise it to the vertical. The Safety Securing Latch automatically latches when stair reaches the vertical position.
