Greatings from the "Colonial Markets’ {thanks Carryfast mate}
Well you’ve clearly never been to NZ and defiantly not in the 60’s and 70’s if you think the roads are similar to those in the UK. There are still very few motorways here only in Auckland,Wellington{10kms} Christchurch and Dunedin. There are are very few duel carriageways,really only south of Auckland and around some of the main centres.
The remainder of the roads are single carriageway with the occasional passing lane. There are still single lane bridges where you have to stop and give way. Railways lines are still driven over. Lots of long steep hills some with switch back hair pin bends,one pass in the South Island was re-aligned recently but still has a grade of 12%,one metre climb for every eight metres forward and is 5 kms long. It takes a loaded truck over ten minutes to climb and descend this.
These are the roads in 2013,imagine what they were like 40 years ago? Many were still not sealed
Wellington to Auckland if about 650ks and takes about eight hours. I was recently talking to a couple of old drivers who used to drive the same road in the late 60’s in LAD and Ergo Octopus’s with trailers at near 40 tonne and it took them 27hrs. Like this one below.
I was talking to a mate who told me on one particular long pull he was down in first low in a 680 twin stick Leyland Hippo tractor unit pulling two trailers,with the motor down at 800rpm and a cyclist pulled past him! Some idea of the hills and the weights carried.
Here’s and Octopus fitted with a turbo 690 pullong an ‘A’ trian.
Another Octopus carting wool,with about 100 bales on which works out to roughly 20 tonne payload,truck and trailer probably 15-16 tonne,not a bad all up weight for a 200 horse 680.
These were much better trucks with 13 speed fullers,far more flexible,with a quick change,not like the the twin stick box,where you could roll a smoke and have a cupper between changes. Kiwi Ergo’s both MM8 and Octopus’ worked hard,but as a mate said 'They were on top of the job"
A good load here.
Many Ergo’s were re-powered,but as you can seen not before they did a bit!
Detroit two stroke strait 671’s were a popular choice,they were cheep and most importantly ideally suited to and ergo chassis with it’s restricted chassis access and fixed floor pan. They can be configured with the blower and intake as well as the exhaust manifold on the left hand side of the motor,leaving the right hand side free of any components.
