G'day.
The first thing you may or may not notice is the slightly redesigned layout of this page. Hopefully it proves to be a little easier to read and appears a little more up to date.
Another couple of interesting weeks have flown by, so much to do, so little time to do it. Last week was a week at the mine. That was stupidly busy actually, probably enough work for two men that week. At the end of the day you can only do what you can do, so you do your best and anything that doesn't get done just has to wait.
They had a shovel down for some major maintenance, and whilst it was down they thought it would be a good idea to install some new equipment in it and run some new antenna cables. Of course this then became a task for yours truly, and I spent a large percentage of two days carrying out that task. I ended up having to take the roofing panels out from inside the cab, and luckily managed to con an apprentice to help me out as these are big heavy panels and somewhat difficult to man handle on ones own.
Anyhow, we got the job done, and spent the rest of the week running around fixing minor issues here and there. Friday was an interesting day, usually you try to start a little early on a Friday so that you can get away at a reasonable hour for the almost 2.5 hour drive home again. That was all well and good, until I discovered that I had been tasked to install some new antenna cables into the main office complex building that day. We scoped out the job, and it was a major task. I asked the leading hand for an apprentice to help out by driving a JLG (kind of like a bucket truck without the truck) as I am not currently authorised to use one on the mine site. He ended up giving me 4 apprentices for as long as I required them, so it turned out to be a little easier than anticipated. Two of us went up in the bucket, one was a spotter, and the other two ran the cable internally in the roof, so we managed to turn it into a fairly streamlined performance. As it was, we still didn't finish until three, so had I been doing it on my own I would have been there until Christmas.
Monday I was back in the workshop, and had a bit of a job to go and install a new antenna and cable to the top of a cement silo at a local concrete plant. After we managed to fabricate some necessary metalwork we travelled out and installed it to the silo. I had one drum of the particular cable we needed left, as it was all I had anyway I didn't bother measuring the tower first, we just terminated it and rolled it out. By the time we got right down the silo and into the batch hut, I cut off the excess. Which was precisely 20 centimetres. Pretty lucky on that count, then. Usually with my luck I would have been at least that amount on the short side.
Tuesday I spent in the workshop doing repairs and preparing a special piece of equipment for installation at another mine the next day.
Wednesday I was at said mine installing the specialised equipment. Or at least, attempting to. Unfortunately this had turned into one of those "not much goes right first time" jobs.
(This was the second time I had attempted to install it, the first time the equipment was sent direct to the mine and when I showed up to do it, the cables were missing, the equipment wouldn't fit in the rack, the power supply was the wrong voltage, and a few other minor hiccups. I ended up taking the whole lot back to work to sort it out. )
That aside, I had a new bracket fabricated, all the gear measured to fit, and all the required connectors this time. The first job was to fit the new rack to the trailer in which it was being installed. Except the hinge was a different diameter to sample one I had given the engineers. Luckily my step drill sorted that problem out. Then the hinge pin was too long to fit... So, with the aid of my hacksaw, I managed to sort that one out too. (The hinge is about 20mm stainless solid cylinder... took me flaming ages!) Thirdly, the pins which locate the other side were not lining up with the predrilled holes, so I also had to slot those out to get everything to line up.
Finally getting the rack mounted, I managed to install the equipment with retaliative ease, as I had pre measured that at work. The cables all fitted well, and it went together with no further issue. Until we attempted to mount the aerials, that is. The mine had made an extension to the standard trailer pole, as we needed to have some separation between our antennas. I went to mount the top one, and discovered that the pole was 20mm too short for the top bracket to fit. Because of the design of the pole with the guy points welded on, I couldn't slide the aerial further down. We ended up going back to the workshop and had an extension fabricated. That solved that problem.
Then we went to stand the pole up. The theory was we should be able to pull it up with the guy ropes... but long story short, it wasn't that simple, as the hinge point is about at head height. I won't go into detail as to how we finally got it standing, but if any mine safety inspectors ever see this, of course it was done very safely with no risk to any one at all. Honest.
We then tied off the rope guys to some "star pickets"... waratahs to us Kiwis. Luckily we had an apprentice on hand to drive those into the ground... as funnily enough, when you are driving into a spoil pile made of rocks, you tend to keep hitting... rocks.
I then went to shut the cabinet door so we could leave. "Thunk". Turns out the handles on the equipment hit the door of the trailer... brilliant. So I had to take the gear back out of the rack, and work out a way to unscrew the handles. Luckily it wasn't too complicated and we soon had the door closing properly.
In the end it all appears to be working, we didn't have the required equipment on hand to do real life testing but no doubt we will find out if it's no good.
Thursday was supposed to be a nice easy job, putting up a couple of radio units for a simple data link across a road. We showed up right on 8, expecting the JLG to be ready and waiting... but no sign of it anywhere. We chased up several people and long story short, we ended up having to wait to almost 11:00 before we finally made it into the air to do a 10 minute job. Once we had the roof access, we easily ran the cables and mounted the equipment, and strangely enough, it all worked first time. I think the only setback there was I think we left the drum of cable behind, I must make a note to go and retrieve it at some point...
Friday. Oh yes... Friday. This day put the icing on the cake really. Another data link going in, not a difficult job, should have been as easy as the one the day before. We showed up on site right on 7 o clock. We had a crane there already setup, and the dogbox was on it's way. It would have been a 10 minute job once the dogbox arrived on site. I saw would of, because at that point, the only other person in the building who was there at that hour of the morning walked over and introduced himself as the safety man for that site.
The conversation went something along the lines of this:
"G'day, what are you guys doing with that crane?"
"G'day mate, well, it's quite simple, we are going to nip up there and replace that aerial on the roof."
"What, with that crane?"
"That was the intention, yes."
"Well I'm afraid it isn't that simple."
"Oh it's not difficult, we just hop into that basket, and the crane lifts us up. Quite straightforward really."
"No you don't understand. You see, we don't allow cranes and dogboxes on our sites."
"OK, well this isn't really a site is it... more of a carpark, really?"
"I'm afraid that doesn't matter, our rules still apply. You can't use that crane here!"
"OK then... why's that?"
"Our rules state that it is to be used as a last resort, they are too dangerous! What about that power line there!"
"Interesting, they seem to be safe enough to be used on every other site around here... and the power lines don't come into it, as they are more than 3 meters away at all times and are double insulated 240v, so they are not really a risk to our operation."
"Nope, only used as a last resort. You could scaffold it, so that's not yet a last resort!"
About here the crane driver interjects...
Driver:
"Look mate, I know you have a seat to fill and you don't want to lose that seat, I know that you need to justify your job somehow, but let me assure you, this is not a dangerous task!"Safety Guy:
"That may be well and good, and we can go back and forth all day, but I am telling you now, nothing you do is going to make me change my mind."Me:
"We could go and get a helicopter I suppose..."Safety Guy:
"Splutter"Me:
"Righto lads, lets pack up and go... jobs off.So I ended up back in the workshop for the rest of that day too. Our boss talked to his boss and long story short, their high up overall boss man is flying up from Brisbane next week to have a meeting with me to determine how we can safely undertake the job. I think I shall suggest a crane and a dogbox... and if they don't like that, I might supply him with two tin cans and a piece of string. The dollars they are throwing at a stupidly simple job is just plain ridiculous, this literally will be the worlds most expensive data link if they keep going at this rate.
Anyhow, I will no doubt find out more next week.
As the old Warner Brother cartoons used to say...
"That's all, Folks!"
