The way we were

[FOWLER MAN]

Hello John,
Thanks for your reply.
I knew about thr Blaw Knox "Hydrascoop" theres a pic of one working on page 24 of this thread.
It was basicly a BK 50. It used the BK50 undercariage and running gear, bottom end and travel machinery. An uprated Perkins engine and the BK50 winches. The hydraulics were only used to crowd and tip the 1.1/2 yard bucket and I think to push it forward
I dont know much about the spec. but it had 12 ft. level bucket stroke on the ground and a discharge height of 9ft. 10 inches. BK advert below with same pic as you posted.



I don't know what model Lovatts Northwest was, I thought it may have been a 2.1/2 yard 80D but looking again I think it's probably a bit smaller. The one I worked on, (and I don't remember the model), had a Brilliant Murphy Diesel in it.
I have plenty of pics. showong the same type of gantry on various models.

Fred,

I couldn't tell by the photo I had seen, but your advert clearly shows the cable hoist arrangement. So; I guess it's more like a Koehring 205 SKOOPER (photo attached) than the Insley HL-5000.

One thing that is a bit puzzling is if it only had a 1.5yd3 bucket, how in the world could it load 5yd3s in 45 seconds?

Out of curiosity; what is the print date on the 80-D brochure you posted the cover shot of?

'All the best,

Hello again John,
Thanks for the reply,the brochure I posted is undated too.
I know that Northwest Engineering introduced the 80 in 1933, it was replaced by the 80D in 1937 and the 80D remained in production till the early 1980s. They apparently made over 2,600 of them.
There were constant improvements and by the early to middle 60s the Murphy engine had been uprated to a Turbocharged "model 21" giving 178 hp. @ 1,200 rpm. The capacity had been increased from 2 to 2.1/2 yards and they were on full air control. The 80D weighed 65 tons.
I too have pictures of the 80D with the gantry illustrated, with a taller gantry and with no gantry atall.

As you say it's hard to see how the Blaw Knox could load 5 cu yards in 45 secs.
I suppose you might get two cycles in 45 secs. in perfect conditions. So if the bucket had a struck capacity of 1.5 yards you would have to get an extra yard heaped on top each time.

Peppers, the firm I worked for who had the BK50 also had a Koehring 205 Scooper, (see below).
Theres also a very interesting bonneted Thornycroft "Big Ben" dump truck in the pic. I never had anythong to do with either of these.

That Big Ben has more than a touch of Mighty Antar about it.

You must have read my mind I thought the same when I saw it.

Hi Angus and Jeremy,
Are you both too polite to say you think I got it wrong

The bonneted "Big Ben" was developed as an oilfield truck with 200 hp. AEC power and 6x6 or 6x4 drive and it does look like the "Mighty Antar." (Advertisment from commercial Motor 1963).
There was also a "Big Ben" crane carrier chasis.

Me , polite? only on leap years!
I looked at it , thought Antar but realised that the bonnet was not wide enough . Never seen a tipper but very similar front end to the oil field trucks that they used to build - the ones with the flat bed and winch for uplifting skid mounted equipment.

There is an article on the Big Ben that I recently saw while browsing the truck 'rags' in a certain famous newsagents so I knew that it was a real truck and not the mighty Antar.
