Never Seen This Before And I Want One!

I was on one of the construction sites for the Sound Transit expansion to Federal Way.  As I walked around the parking garage that was under construction, I came across a piece of equipment I had not seen before.  I have seen machines for working the surface of concrete before but this one has two rotating elements under a seat.  The operator rides on the machine.  It looks like some kids version of a jet pack.

The better news was that a second one was in use on the upper levels of the parking structure.  When I got up the tower crane, I was able to shoot a little video of it in use.  It is a curious looking piece of machinery and, having never seen it before, seeing it in use really made me smile.

Drilling a Shaft

I was doing a visit to one of the construction sites that our team at work is managing currently.  There is a lot of elevated guideway as part of this project and that involves drilling shafts for the elevated structures.  The drilling was not underway at the location we stopped off at so I could see some of the drilling equipment.  Not only was the auger like drill on site but also the cylinders with cutting heads mounted on the edge which are rotated in place by the other tool next to the drill.  The crews can drill these holes at quite a rate when they are going and the result is that the structures are springing up across the project at this point.  Nice to be part of something that will be soon serving the communities in the south part of King County.

Retired Machinery

As soon as you leave the parking lot, a selection of machinery from one of the mines has been relocated to let you see how the mines got everything up and down.   The big steam pistons, cable reels and the lift cages the guys went down in are there to wander around.

wpid11365-AU0E8835.jpgThat isn’t all though.   There are quite a few bits and pieces scattered around the town where they were left. A couple of vehicles are on display in good condition. These are interesting but the ones that were unreserved interested me far more.   The metal parts of small trucks have survived while the wooden frames have rotted away. They leave the skeleton like parts slightly sunk into the ground giving the impression that the whole vehicle has sunk.   The missing bits leave scope for the imagination to wonder at how the whole thing looked.   It is also a detective task to work out exactly what some of the remaining parts are and what joined them together.

wpid11369-AU0E8841.jpgVehicles aren’t the only things to find. Some other machinery is scattered about and that involves even more thought as to what it was for and how it ended up dumped in its current location. The condition of the metalwork is remarkably good. I have no idea whether the park service has done anything to sustain the items but they seem to be petty resilient. I imagine the climate helps to keep things in good shape so hopefully they will be there for generations to come.

Michigan Avenue Bridgehouse

The Chicago tourist activities have been continuing.  Another local attraction I have never been to – and this one has no excuse since I have known about it for ages and it is visible from my window! – is the bridgehouse for the Michigan Avenue bridge.

Chicago has a large number of movable bridges across the Chicago and Calumet rivers.  A large number of them are bascule bridges.  For those of you not familiar with French descriptions of bridges, bascule bridges are counterbalanced and rotate out of the way using very little power due to the excellent balance.  (Bascule is French for seesaw.)

The museum is in the tower at one end of the bridge.  It is a pretty small museum but it provides access to the mechanisms that move the bridge.  This is something that interests an engineering type like me.  I think they could have made things a little better though.  There is very little lighting down there so it is hard to make out all of the parts of the machinery.  They could also provide a bit more of a guide to this.  As a photographer, the amount of fencing in the way is a nuisance but I doubt there is much they could do about that.

As a result of the relatively limited nature of the bridge, the rest of the museum is a history of Chicago, its rivers and the water supply.  It certainly provides more to look at and is quite worth a look.  There are also some slightly different views of the river.  Since it was only $4 to get in, I think it was worth a look.  Now to see how I can make some suggestions to them about improvements.
