My old Molnar is 35 years old. I talked to the repair /maintenance guy and he said that the cables would need replacing after 10 years. But as I don't use it everyday, I got a bit slack with maintenance. I did grease the pulleys and looked at the cables. So now I'm a little nervous and looking into a new hoist or repairs. The new style hoists mainly use a hydraulic ram in each post with a chain over a pulley on each ram. So the base plate only hides a hydraulic hose and a small leveling cable. So it doesn't support the main posts. Therefore the minimum concrete thickness is 150mm and you are totally relying on the dynobolts to stop the post wanting to collapse into the centre. The Molnar hoist has 2 large rectangle channels under the base plate and the post bolt to the base plate. It can almost free stand. So all and all, they are a very strong hoist.So I'll be overhauling mine. The cables only cost 600 dollars. So any one looking for a hoist, you really need to look into them.The free floor one would be better as the overhead bar will strengthen the upright. But you need a high shed. Otherwise a 4 poster would be stronger.
