[SPAM][BL] Snow, glorious snow.

John,
Definately not an error. The pill would only be 23 tons if it was being
hoisted straight up. The pull drops dramatically as it gets level. Using
guesswork I imagine that a flat pull of a 2.5 ton cruiser is about 3/4 of a
ton, once moving. To get it moving, a bit more. The low range box is made
for stuff like this.

I must agree it would only be that heavy if it was lifted. Its not exactly
a straight rolling load either because there is quite a gradient. Still it
shows the strength of the cruiser.
It basically spun the wheels all the way up and I know I wouldn't be brave
enough to subject the axles & diffs in a Land Rover to that kind of abuse.
Having broke plenty whilst off roading in the past!!
The truck weighs that much because of the crane (65 ton a metre HMF) and the
heavy hook loader equipment fitted as well.
Cheers

Hi Clive
Thanks for that but can you explain a bit more about the lifting weight V the pulling weight. Its another thing I have to understand.
cheers

The "lift" weight is the actual weight, ie what you would have to lift
if you hitched up a crane and lifted it off the ground.
The "pulling" weight is that required to pull it along the ground.
This depends on how level the ground is, how far the tyres have sunk
into mud or snow, how much friction there is in the transmission ...
lots of things.
In fact if you had steel wheels on a level steel track, such as they
have on railways, the resistance to pull is incredibly low and it is
quite normal for goods trains to be between 1000 and 2000 tons - or even
10,000 to 20,000 tons for iron ore trains in Sweden and Australia. The
killer is the hills: as soon as you get any uphill gradient you are
trying to "lift" that load as well as pull it along, and that makes it
much harder (it also explains why railways dig through cuttings and run
on embankments, rather than following the contours of the land up and
down).
This also explains why you and I can push 2.5 tons of Landcruiser on
level tarmac, but that if it is stuck in a slight rut we will probably
be unable to push it out.
