This padlock has, starting from the front, one spring, one slider/lever, a second slider/lever and a second spring. I observed the levers and springs movements while using the key. With the first turn the key lifts the first spring and then moves the first lever. With the second turn the key lifts the last spring and moves the second lever.
Each spring locks its lever, lifting the spring allow me to move the lever left and right.
I used a tok tension wrench to lift the first spring and a hook to move the first lever right. Easy. Then I had to insert the tok tension wrench to the bottom of the keyway to reach the last spring, this was not very difficult, but the first one was a lot easier since I could clearly see it. While keeping the spring up I used the hook again to move the second lever. At this point the lock was picked.
