@@john23215 AVANT made one, about 10 years ago. It actually ties into the AVANT Hydraulics, has controls from the cab, and is pulled from the back. Thanks though
This is a Chinese made timber trailer, ~2016 model year. In theory 3 ton cargo capacity and the crane should be able to lift ~300 kg at max distance of ~3.9 meters. I've added the ISO quick couplers to use it from Avant auxilary hydraulics but this time I forgot to bring the hoses and had to use the onboard pump with gasoline engine.
