Container loading ramps

[n428]

After soe advice- not sure what section to put it in.

I've got to load a large object into a standard shipping container. The container is being craned off the lorry so is at ground level. The load weighs approx 2000kg and will be on caster- and relatively easy to roll with 4/5 people.

What I'm trying to work out is how high the 'lip' into the container is, and how I can get the casters up this?

Some kind of ramp?

Cheers

If that's not too much trouble- I have a 1 hour loading window!

Any ideas would be great..
