Got up at 07:00 and spent a pleasant day wrestling an 8.05m long RSJ into my 8.1m long shed, then maneuvering it so that it was on the far side of the crane A-frame that I'd lifted it in to the shed with. This involved an auxiliary hoist and poking the end of the beam out of the hole in the back of the shed that's supposed to have a window in it.
Unfortunately, mid-afternoon the pendant for the electric auxiliary hoist managed to weld all of its switch contacts together (Up and Down). This lead to a release of magic smoke into the environment and a certain amount of bad language. Leaving the beam held up at one end with the gantry crane and resting on a step ladder at the other end, I trotted off to Screwfix and got one of their little 1 tonne chain hoists. (The 2 tonne one is only £10 more, but I needed it now, not tomorrow…).
Having fitted the new chain hoist to the trolley that had held the electric hoist, I managed to get the beam on the far side of the gantry crane with only another three hours effort.
After A break for teatime I finally got the beam suspended over the four columns that are supposed to support it and the bolts placed in the mounting holes. I called it a day at 21:30. Tomorrow I'll have the simple job of tightening all the bolts, leveling the beam with the jacking screws I put in the column feet and screwing the columns to the wall.
The whole project is aimed at converting my gantry crane into a bridge crane so I can move things up against the shed wall instead of having to waste a couple of feet for the gantry to run in.
PS:- the Screwfix chain hoist might have a rated load of one tonne, but I'm not sure that it has the industry standard 4:1 safety factor for lifting chains.
