I don't need measurments... You only have so much lift available. Please forgive me if I get to basic here. If the arms go well below the lift pins, then that is where your lift is being wasted. I am not specifically familliar with your 3PH, but if it is along the standard lines, You should have adjustable links that connect between the upper and lower lift arms. These links, usually a turnbuckle affair, are adjustable in length to fine tune the height of the lower arm. There are also usually several attach points along the length of the lower lift arms. Attaching the links to different points along the lower arms allows you to trade lift force for lift travel. Attaching closest to the tractor on the lower arms gives you max vertical travel at the ends of the lower arms where the impliment attaches, but it reduces the lift capacity to it's minimum. Attaching the links out near the ends of the arms away from the tractor gives the minimum vertical travel, but the greates lift force. Depending on the weight of the impliment, you may have to comprimise the desired lift travel to lift a heavy impliment.
