Started moving the material and equipment in place today for removing the dock ramp and I spent the rest of the day on the Willapa River looking at the boat launch, the tow area and ramp as well as looking at the RR Bridge. The bridge is impressive and I will post one photo now. Took lots but will cover it later with additional photos.
We actually did some calculations on the weight of the ramp and came up with a total weight of just under 3300 lbs. As Roger and Bob suggested, the ideal way would be to lower the ramp into the water and after doing our calculations I think I can add a 6x8 beam on top of each railing on the walkway so it extends about 18 inches beyond the railing and hook a come-a-long on each 6x8 beam down to the cross beam on the ramp. When the tide is in with the drums strapped to the ramp it should float up. We then take the tension off the pin with the come-a-longs, knock the pin out and lower it to the water. It will take two sets of come-a-longs because of the distance.
We then build a transom on the ramp, hook up the 8hp outboard and tow it to the boat launch. With the engine on the ramp we will not be as pressed for time to move it down river. Even with an outgoing tide we will have some ability to slow the ramp down and will have better control of the ramp. The boat ramp is a real shallow ramp so that will create its own challenges. The boat ramp was busy today and Sunday I expect it to be even busier. We may have to wait until Sunday evening or Monday morning to haul it out of the water.
Brent you are right, that is what I call a track excavator. In fact, I use to have one similar to the one you linked to when I was logging. The one I have now is much smaller so I can move it around on a 14,000 trailer with a pickup.
Charlie – I never thought of videos, mostly because all of us are 69 and older and never learned to operate these new fangled hi-tech pieces of equipment and my hands will be full doing as much of the work as possible. So I called my son-in-law and asked if he would videotape us.
Tug – I thought of dismantling it but would be extremely hard because of its steep angle, it is over mud (soft, sticky, gooey mud) and the low end will still be two feet under water at low tide.
The rr-bridge will not be done this year. It can be done if it does not fall apart in the process.
Joe & Chester – you guys are right, it is a rail to trails bridge that I would gess has not been closed in over 35 years.
