Self Adjusting Stair Gangways
Simple, fast access to the top of any loading situation
Application
Click image to enlargeHemco's self adjusting stair gangway (SAS) provides safe access where there are big height differences in tankers being serviced from the same elevated walkway. Standard models are made in 3 tread, 4 tread, 5 tread, and 6 tread, to reach out as far from the elevated walkway as needed. Longer are available, but may need hydraulic assistance for ease of folding up and down.
Operation
After the Safety Securing Latch is released, a slight push out on the top of the stair, spreads the treads as they remain horizontal to reach out as far as needed to meet the top of the truck at heights either above or below the elevated walkway. The tension spring balance mechanisms located in the housing on each side keep the stair 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 stair. The Balance Mechanisms will gently raise it to the vertical. Safety Securing Latch automatically latches when stair reaches the vertical position.
