I bought this for my hubby as a present, he’d had a heart op a few years back and is on blood thinners, needless to say if he strains by lifting something too heavy, kicks off internal bleeding. We’ve been moving house and with this we are able to lift to trailer height, smoothly lower, it works great. The unit its self is about 50kg. The poor delivery driver! With luck we were here when it was delivered. Limitations are once loaded you won’t get it over a door edge from outside to in, need to transfer to an indoor trolly.
