BOG-INS ON SITE
CAT 769 bog-in at Long Pond on 26th January 1984
The CAT 769 has very hard high pressure tyres and was going down the haul road to the Long Pond dump too fast. The bulldozer has a hawser attached to the dump truck to stop it falling over. The D9 is pushing more rock around the side so that the dumper has something to climb back onto.
The Cat 769 carries about 50 tonnes I believe and it must weigh about ten tonnes itself.
CAT D225 bog-in at the secondary runway trial pit on 9th February 1984
James M wanted to test the peat depth in the middle of the future secondary runway where it was obviously deep near Champina Pond.
This excavator was the one with bog tracks but it still slowly went under as the vibration of digging the hole made it break through the grass so that the tracks completely disappeared. God knows how they got it out.
One of Dave O's bog-ins was on site. I caught him on 18th January 1984 near Sand Pond. The grass was extremely tussocky and he obviously found it hard going so he made for smoother ground nearer the pond.
His front wheels went over the edge of a small ridge, his middle grounded on large tussocks and his rear wheels came off the ground. It was the only bog-in I saw where all four wheels were off the ground. Not strictly a bog-in but I still scored it.
George L was already trying to help him, but we had to pack quite a lot of timber under wheels to get any grip.
No photo - you're so lucky, Dave. I'm sure I took a photo, and of several other bog-ins, but the films got lost in the post I think.

Overturned Leyland bowser lorry near the site camp on 26th November 1984
Someone had taken it for a joy ride late at night
He must have been going too fast downhill and rolled off the road
