Hoist for delivering logs and loading timber

[flatyre]

Am thinking of fitting some sort of hoist into the back of the tipper to aid unloading bags of logs and occasionally timber. Want something that can be removed easily on days when i'm chipping into the tipper. What sort of hoist do you guys use for delivering logs or timber, even if you don't chip into the same vehicle?

I need something similar to get my 100kg pedestrian stump grinder on and off my van.

I had a Lucas swing lift on the back of a Nissan Cabstar, worked ok for delivering bagged logs/dragging stuff on/off.

 

I bought one like this afterwards but never fitted it......
