I maintain the dock levelers at work but I don't understand how they work. Could some one help a confused one out ??? There is two cylinders. One lifts the plate and one lifts the lip... I drew out exactly the way the hose's run. Both cylinders move out when you push the up button... How can this work with the drawing below? The second cylinder looks like it should pull in not out. And the first cylinder looks like a dead short or a brick wall... The Big number 1 cylinder moves out first and then #2 moves out...
