Just a quick pic I took several trips ago at Yarrie mine site. I was waiting at dawn at the main gate to the site and snapped a few picks like this one.

A Letter To Main Roads Western Australia
October 31, 2011Submission as follows :
Potholes appearing on Gt Northern Hwy around SLK142, also at Bindi Bindi T intersection Gt Northern Hwy (unsure of SLK). My main concern is the lack of room at the Wubin roadtrain assembly area. I use the assembly area 2 to 4 times a week and am frequently frustrated by the lack of room despite the last upgrade.This is also a major problem at the Newman roadtrain assembly area-I have been unable to access this area on my last three trips to Newman and have utilised the Turf Club parking area as well as the first parking bay north of the Newman townsite (on the Gt Northern Hwy) for the purpose of splitting triple roadtrain trailers for the delivery of freight to the Newman townsite. I am aware that plans are in motion for upgrading the Newman roadtrain assembly area but are there plans to further extend the Wubin roadtrain assembly area? As I see it roadtrain traffic on the Gt Northern Hwy stands to increase by a significant amount before anyone could reasonably expect it to plateau and eventually decrease sometime in the far distant future when the iron ore mining boom finally loses it’s momentum. Until that time the road infrastructure must keep pace. That also includes the many inadequate parking areas dotted up and down the Gt Northern Hwy-inadequate because quite often only two or three trucks can fit in each of them. In fact, some of the parking areas are so restricted that if three trucks fit into them then they must leave in the precise order they arrived in – there is simply no room to get around the truck in front. Hopefully the first truck “in” doesn’t expect a sleep-in. This is an age when more and more responsibility is being forced upon the driver and as a driver I am being forced further and further into a corner. To get out of this corner I need the freedom to stop in a parking bay that has room for my truck when I need it, I need to have spacious roadtrain assembly areas (with night lighting-pretty please) to assemble and disassemble triple roadtrains, and I need to know that “those-who-must-be-obeyed” have some concept of the hurdles we face. Until then, catch phrases like “fatigue management” and “safe work practices” are just…well, they’re just bullshit.
Well, I hope that gives some context to my more recent tweets. If you want to follow me on Twitter there is a “Follow” link on the sidebar.
Cheers, Mike.
Customer Service Drama’s
August 10, 2011Had a bit of trouble with the truck this run. A “Check Engine” light appeared briefly on my way back into Perth last trip and we put the little computer on her and checked out the error codes logged on the onboard computer and came up with a couple of turbo overspeed errors. There wasn’t a lot we could do at that stage so the descision was made to head out on the next run and monitor the engine and see what happened.
The run went alright, for the most part. The error came up again and the engine was derating but only enough to be a small inconvenience – fortunately for me. The problem really became apparent on hard climbs where the truck was really grunting. Arrangements where made, on the Monday, with Cummins in Perth for the truck to be looked at on Tuesday after I had got back. All the symptons were explained over the phone to Cummins in the hope they would have a bit of an idea what they would be dealing with and (maybe) be prepared with mechanics and parts to fix the problem.
Well, I got back a bit later than I had planned. I had been feeling pretty secondhand all day, not quite sick but definately not 100%, and I rocked in there late in the afternoon too find that no-one knew I was coming. Eventually I found someone who “remembered” someone else talking about it. For Christ’s sake – don’t people in the same organisation talk to to each other about their work, ie:services they are supplying to customers who are their bread and butter and without whom they wouldn’t have a job?! I didn’t take the truck into their workshop because I wanted THEM to work on it – I took it there because it had to have work done on it and it ended up being a warranty job anyway. They OWE me!
Ok, we get over that little hurdle, they promise to try and look at it that night. I tell them I will need it back by 4pm the next day at the latest, hoping that it will be ready and I can leave that night and do a run with it – you know, so I can feed myself and pay the bills.
This morning we discover that, yes, they know what the problem is and, no, they don’t have the parts and they will have to be flown in from Melbourne overnight and fitted tomorrow. Now it’s not as though I have some obscure type of turbo (actually, it’s the wastegate that is the problem) and I am asking the people that build and sell the motors to actually fix it so why haven’t they got sufficient spare parts warehoused in Perth? Why do they have get spares from the other side of the country for a motor that is as commonplace as duckshit around a pond?
While I am not going to knock back the opportunity for another night at home I am going to take a hit in the hip pocket because of lost wages, my boss is going to take a hit because the truck isn’t on the road and the company we subby to is going to have to find someone else to do the job I would normally do.
I ask you, would you be happy being screwed around like this because a major engine manufacturerer can’t (or wont) keep enough spares locally to be able to deliver a reliable and timely service to their customers? It’s not like I can just drive over to another Cummins branch and get the work done – this is Western Australia and the branch I’m at is the main one for the state.
So, I’m sitting at home looking out the window at a heap of leaves that I should put in the bin, cursing the cold weather and wishing I was up north somewhere where it was warmer. Oh well, I got another blog entry up.
Cheers, Mike.
PS : Just got off the phone 5mins after I posted this entry – Cummins have managed to “find” the parts somewhere and the truck will be ready shortly. Unfortunately it’s too late for me to organise a run tonight (it is 4:45pm) so the end result is the same. Cummins Fail!
On The Level
September 20, 2010Been having a constant problem with my trailers wandering all over the road this trip. At first I put it down to the strong winds we have experienced in the last couple of days. Then I was checking all my tyres with a pressure gauge (after I used a gimpie on them – see previous post) and I even put some extra grease on the fixed turntables. Nothing helped.
Then I realised all three trailers where traveling nose high and tail low. Now, I got to say that each trip I will have different trailers and different dollies and that slowly creeping (down) ride height adjustments on the fleet of trailers doesn’t seem to feature on the workshops “tick n flick”.
So, based on previous experience with saggy arsed trailers, I crawled under each in turn and adjusted the airbag ride height valve until they where sitting as close to level as I could make them by eye. And it worked.
Instead of shambling down the road looking like a train wreck that was at the “waiting for the dust to settle” stage of a truly spectacular event, they now tag along obediently and I’m not getting the cramps in my hands you get when nothing you do with the steering wheel up front can possibly explain why you can read ALL of the signwriting on the sides of all three trailers, first in one mirror – then in the other.
Leveling up the trailers didn’t just affect each individual trailers handling, it also had two separate flow-on effects on Dolly No.1 and to a greater degree on Dolly No.2 due to the “whip like” effect generated during the white knuckle moments.
How To Create Your Own White Knuckle Experience.
You will need :
3 x Saggy Arse Trailers
2 x Old Single Point Dollies (A-Frames must be high and slope down towards Saggy Arse Ringfeder when engaged)
Quote : “Remember : Trailers are long, dollies are the short ones.”
(Wise old transport manager)
Note : The values assigned to the measurement of Inches and Degrees are intended only to indicate greater and lesser values-they are not true values.
If the rear of a trailer sways 6 inches out of line with the front of that trailer and the direction of travel it might be, say, 3 degrees off that “straight down the middle” path of least resistance or drag. Now the dolly, being attached to the trailer, is also dragged out of line but it is at , say, 6 degrees out of line because it has to turn sharper to move over 6 inches due to it’s drastically shorter length. Ok, generally speaking, when objects like these move out of line they will quite often move back toward that center line and even swing out the other side of that line like a pendulum. If this doesn’t happen then you will more than likely be able to see in your mirror an impressive cloud of dust rising into the air and a lot of stuff getting very bent and twisted. Now don’t forget that something out of line by 6 deg is going to have a more violent return swing than the trailer that was only a little out at 3 deg.
Also, we have to start looking at the 2nd trailer which is hooked up to the dolly and has just been shoved further than 6 inches out of line due to the more aggressive turns the dolly was forced through and the higher inertia forces. Let’s say the dolly and 2nd trailer were forced 8 inches out of line at the furtherest point our of line on the first swing away.
What does this mean :
A) the angle the 2nd trailer will be at?
B) the distance the rear of the 2nd trailer will be from the center line?
C) the angle the 2nd dolly will have to turn at to follow the rear of the 2nd trailer and the effects of inertia on this equipment at this step in the process?
D) the 3rd trailer, hooked to the 2nd dolly, will be doing what?
Answers :
A) the 2nd trailer will be at a greater angle due to being forced further out of line than the 1st trailer but at a lesser angle than the 1st dolly because of it’s greater length. Let’s say 4 deg.
B) the greater angle of the 2nd trailer means more inertia but it’s length should still enable it to be less than or equal to the the 1st dolly and the front of the 2nd trailer. =< 8 inches.
C) the angle of the 2nd dolly will be 8 deg to keep up with the increased angle of the 2nd trailer over the 1st trailer. Inertia increasing forcing 2nd dolly and front of 3rd trailer out to 9 inches.
D) the 3rd trailer will be going bloody spastic! It's the cracker at the end of the whip – swing it hard enough and all that velocity and inertia will do something loud or bad or both.

Dude, I have no idea which deep, dark recesses of my mind I pulled that from! It started out as a normal post and warped into this.
