Re: My unfinished garage in Vic/Australia
With the highly appreciated help of my dad we managed to do something I have been planning for 2 years, I now have this sucker up in the air:
It's a 150 x 75mm (6 x 3") medium gauge I-beam/Girder at 6.8M (22') long. As shown it is sitting up on a step which is welded on for two reasons- to lift it to the highest possible position for the most clearence and secondly to have a level surface to sit on. I have a tilted roof so that C channel under it is on a gentle angle. Not shown in the picture is a heavy gauge flat bar to feed the force into the C channel from the screw-bolt support wall plate. My dad brought his Bob-cat in to hold it as high as possible and then we had to use wood, bricks and some brute force to move it around to sit on my pre-prepared mountings.
Also of note only one end is welded to the plate, the other just sits on the step where some plates on either side will sit to let it slide. This will allow the beam to expand and contract as much as it needs in the heat.
Now with that up it's dedicated for the following:
It's rated at 500kg (1100lb) which I very much doubt however the engines and other bits I need to move around are highly unlikely to weigh even a third of that.
I bought a girder trolley which I modified to have two flat bars that bolt to the engine winch. Thinking ahead I had to mount the girder trolley in line with the wire drum, if not the whole unit would tilt under load and no longer be moveable. I moved it as close as possible but couldn't make it dead inline due to bolt clearence.
Before I even put it up I figured I had a contradictory situation- now the trolley wheels where close to inline to the wire drum it wouldn't tilt forward under load but without a load the weight of the motor would tilt it the other way! I could of put a counterweight on it but I thought it was unproffesional and I went for the more comincal looking idea of the small wheel as shown on the left of the unit. Being like this it's flat at all times and it rolls around really nicely.
What's even funnier is where that wheel came from....
Missing something? An unknowing thanks to my neighbour up the street for putting this in the roadside garbage about 6 months ago, free is good!
Next on the list is a power feed system fit for a factory. Here are the parts:
This is a "semi-flexable" stainless wound rope which I am going to suspend between my walls parallel to my I-beam. On this cable will be some chain links that get to slide up and down the steel rope, then at intervals the power cable will be cable/zip tied to the links. What this will mean is that the cables will start in loops whenat one end and then pull untill almost flat as the crane reaches the other side of the shop. I have had a single dedicated outlet next to the cealing on one side which I put up 2 years ago for the task. The end result will be permenent power without any inconvenience.
The best part of this whole project is the cost, or lack of it, heres the tally inc shipping for each item where applicable:
beam/girder: $200
girder trolley: 100
Engine winch: 120
cable and all accessories: 100
10M lead: 10
total cost: $530
which in comparasin the average engine cranes is about $350. So I think I have done well.
In a twist of fate I might be needing my cars engine out very shortly due to a nasty sound after using it at 8500 revs for a while. Which should of been easily within it's safe rev range long term.
I will post a picture of how things work out with the power feed when I get to it.
