Best choice I ever made, awesome unit. Happ 2 post exceeded everyone else’s, the fact that me being 6 foot I was able to walk under the 4 arms all others I had to walk between arms or duck under arms. Mine is the one that you have to walk from one side to the other to separately release the locks to lower it, but I simply ran a rope to pull whilst at the motor control. It’s been outside for a few years now, I sprayed chains wires etc with Tecktyly anti-corrosive, I keep lots of grease on everything regularly. I’m extremely happy that I made the right choice getting a HAPP hoist I use it regularly, I have 13 collectors cars.
