Leyland DAF T244 - Overlander build information

Postby Tom_DAF » Wed Feb 12, 2020 11:34 am

Hi all,

I'm currently designing my second build on a T244 and being a bit more thorough this time as it's for someone else. I thought I'd share more material as we go along this time. Perhaps some information is useful to others contemplating a build.

I thought I'd start with a chart I made of the Leyland DAF T244 carrying capacity versus where the centre of mass is. I've used the front of the load bed as the reference plane, although it doesn't really matter.

The first chart is illustrative and shows the three lines of interest. The flat line is the total maximum mass of the vehicle (it's straight and has gradient zero because for that criteria the location of the mass is irrelevant. The two curved lines plot maximum axle load against centre of mass. The resulting line (green) illustrates the "solution space", i.e. centre of masses under that line are within all three limits.

Which makes a bit more sense if we look at some real values for an unladen Leyland DAF T244 with the standard load bed:

Hopefully the message is clear: builders do have to account for where their mass is located.

What's particularly useful is that the exercise can be repeated after the build weight is known, to give more info such as roof rack and cab carrying capacity.

That's very interesting, and would probably be similar for any base of similar layout.
While common sense dictates that heavy loads should be placed at or just ahead of the axle it's great to see a builder taking the effort to account for this,and quantify it rather than just putting loads where the internal layout dictates.
It'll be interesting to see this develop

I like the fact that in your image you show the cab steps round the correct way!

A source of much amusement to me! Drives them mad on the FB T244 page!

Yes exactly, the principle is the same for any vehicle. For more axles (6x6, 8x8) you'd have to add another curve for each one however.

I did that specifically for this forum :lol:
