These loads was pulled from the river to the mill on an ice road, level ground, still one hell of a feat, very little margin for error.

wow! that is amazing:thumbup1:

[tommer9]

That is unreal!!

[firewood]

it's hard to imagine how loads of that size were handled before the time of the hydraulic ram and diesel engine.

 

Now we know......great pic cousin jack.

 

even more amazing when you consider that all that timber must have been cut by hand without any mechanical saws and then loaded with pulleys and a bit of horsepower!

Its not really that amazing, ice has a very low friction coefficient like steel wheel on steel rails and ~5 tonnes of horses with studded shoes and a high ground pressure on ice would have more grip to pull than on almost any other surface, so 6 big horses would be able to get over 100 tonnes moving on rails or ice.

 

Be it animal or mechanical HP it takes very little power to move massive weights at low speed, its more about having enough weigh & traction for the power you do have.

 

Look at it another way I weight just under 100kg and I can just about push my Unimog that weighs 6.1 tonnes on flat ground a cupple of meters, that just over 61 times my weight, or look at it another way a land rover road railer will move 300 tonnes and a Unimog road railer will move over 1000 tonnes both at over 15mph

Its not really that amazing,

 

But the photos cool.

 

 

 

Nice find Cj

 

Heritage is what gives us soul

Its not really that amazing,

Yeh, piece of p*ss, regularly shifted loads like that during the recent cold snap.

I know its on 'level' ground, but how would you brake that, as even the slightest decline would cause it to gather speed?

Great shot, CJ, love your horse loggin' porn.

You could'nt brake it on a downhill run, I'm told that the pic was probably as much too show the skills of the loading men and that it would probably ONLY usually be loaded to the top of the bunk uprights, there was just a lot of skill involved all round from the loading, the driving and even preparing the road to make it level.

The picture was from 1908/09, it cannot have been 1808/09 as the first photograph wasn’t until 1814 then it took a few more years to perfect so they were permanent

 

The hydraulic ram was around for quite a few years prior to 1908/09

 

By 1908/09 diesel engines had turbo chargers & intercooler along with precisely controlled injection pumps with needle injection nozzle injectors though it was another ~14 years before they were fitted in road vehicles due to there size.

 

As for cutting & loading semi portable steam mills and steam cranes etc etc ware around though that’s not to say that the timber in the photo was not cross cut by hand and loaded by older methods.

 

It wouldn’t surprise me if the photo was taken in the last year before mechanisation or when mechanisation had just arrived just to show the capabilities of older methods.
