cord to loose again!

[gdh]

What species of timber was the load and did the lorry have onboard weighing?

 

We had a weigh ticket and it was 80/20 ash and oak.

Still confused, I don't know the weight of the load only that it's 18m3, would 1.5 of loose split to 1m3 of cord be a better rate?

 

I reckon in theory you'd get just over 30 cubes of loose split logs from that load. This assumes the logs are 33cm long. I'm not sure of the assumed width of the split logs (somewhere in the Wood Fuels Manual it says).

 

To get this figure I'm assuming your roundwood logs are straight are loaded neatly and that the load is measured at 18 cubes. I'm going to assume that 30% of that stack is air gaps between the logs so the solid wood is about 0.7x18=12.6 cubes. The solid-to-stacked-split factor is 1.5 so 12.6x1.5=18.9 cubes. The stacked-split-to-loose factor is 1.66, so 18.9x1.66=31.374 cubes.

 

If you really need to know the weight ideally take it to a weigh bridge otherwise take some sample of wood, split and measure the moisture content (wet basis) at the centre not face. Look up on the mass density tables in the manual for that m/c based on the correct volume (split-stacked or split-loose). It's not accurate but gives you an idea of weight.

 

I'm sure the differences on what people are seeing are due to the length of the split wood, the width of split wood (one-way or two way splitter, diameter of roundwood used) and also the accuracy of the measured volume of the container for the loose split end product. Some people assume builders bags are a cube when they are 0.7 typically as an example.

All the Math looks right except for the volume on the lorry; I de reckon it'll be 18m3 after 0.7 conversion for air. Volume on 8 wheeler being more like 26m3 (width between pins x bays of x length timber x height of pins).

For previous experience when we have had 8 wheelers delivering, when filled as high as you can go, we have managed 28-32 cube of cut logs. Tonnage was approximately 15-16ton.

[gensetsteve]

One tonne of green beech used to get me 1.4 cu metres of loose logs.

Using 1m3 vented nets by chance?

A bit of 1.5 cu metre dumpy a few Ibc and a 2 cu measured pick up body. If I was getting anywhere near 2cu per tonne I would still be doing logs.

6 wheeler and drag - mixed hardwood species 1.5 - 1.75m3 per tonne split at 200mm.

 

All Beech closer to 1.5m3 per tonne.

[Woodworks]

This is weird. Only weighed a few crates filled to one cube but none of them was over half tonne. Going to have to cut some fresh in wood and weigh again.
