I have been asked to look into designing a system that would allow a lorry loaded with supplies to pull up under a crane, and have all its stores unloaded in a single lift. This could range from a full load of rebar, to a single machine, weighing up to 15t.

The purpose is to speed up unloading so that the crane can get on with construction, and to remove the lorry from site sooner, as logistics and unloading spaces are tight.

Does anyone know if you can under-sling a DROPS rack?  I am relatively sure that the APFB comes on a DROPS rack, and clearly that can be under slung, but I am not sure of the maximum load that rack could carry like this (ignoring the limitation of the hook, the crane is perfectly capable of the loads required.)

I have trawled through the BA Battlebox logistic pamphlets but with no luck. I know that the DROPS can carry 15t and has a self weight of 1.5t, but I do not know if this capacity would reduce if lifted by a crane and not loaded onto a lorry.

Any suggestions?
