I have considered getting one from time to time & finally availed myself of one this week.
My garage has 2 steel roof frames so I decided to attach it to those somehow. The brackets that come with the hoist are designed for going over something square section, just over 40mm sides.
I had a look on ebay and found someplace selling 40mm x 40mm, 3mm wall box section and did click & collect at Argos so I bought a 1.5m length from them.
I picked it up during lunch break today and couldn't help but laugh at the packaging: they had wrapped corrugated cardboard around it and secured it with copious 'Fragile' tape....
It became something of an object of curiosity in the office during the afternoon.
My plan is to bolt the box section across the centre span of one of the frames and attach the hoist to that. I have M10 high tensile anchor studs that I think should be up to the job of holding it in place: the hoist is rated to 250kg but I've no intention of trying to lift a whole bike with it..
I'll get it fitted up tomorrow night & take a pic or two for your perusal.
