Compressed Air / Oil - XHM (AL)-24
Compressed Air/Oil Vertical Leveling, Automatic Leveling, Fold Back, and Manual Extension
Applications: This model is suggested where more simplicity of operation is desired using air pressure power for only leveling and fold back. Extendible walkway rolls in and out very easily - manually with the extension arm.
It is fully automatic with automatic foldback on compressed air of 160 psig (minimum), available at the loading rack. Can be operated on pressure of 100 psig (minimum) with all movements automatic except folding back, where in conjunction with the air pressure, a pull on the pull chain will fold it back.
How it operates
Folding Down: Pull back on top of gangway and release automatic latching device. Extension lock must be disengaged. Push open lever to lift cylinder valve located at bottom of reservoir. Gangway will fold down to the horizontal. Positive stops hold gangway at the horizontal.
Leveling up and down: After the gangway folds down, it is stopped at the horizontal and it will continue to level down. When the desired level is reached, close vertical valve and gangway will be held at this level. If adjusting upward is needed, pressure the reservoir by opening the air valve located at the top of the reservoir. Open the lift cylinder valve and the lift cylinder will level the gangway up. Close lift cylinder valve when the desired level is reached.
Pivoting: With column unlocked, gangway will pivot by hand to the desired angle by pulling or pushing in either of the rear handrail posts. Push down on column lock mechanism to hold pivot position in place.
Extending: Extension operates easily on Delrin (noncorrosive) rollers by pushing or pulling on the extension arm that is attached to and locks to the rear handrail posts. Engaging the extension lock holds the extension arm to rear handrail post and extendible platform cannot move.
Folding Back: With extendible platform retracted and column lock mechanism unlocked, pressure reservoir with the air valve. Extension lock must be disengaged. Gangway will then level up until the fold rod nut engages the folding angle at which time (with sufficient air pressure) the folding rod will fold the gangway back and the automatic securing latch will engage. If there is not sufficient air pressure for automatic foldback, by hand, pull on handle of folding chain assembly to assist.
