If it is the same lift I am thinking of, any higher grade bolt will be
better. The ones that come on the lift are like warm peanut butter.
I just built my own lift. Probably over built it. but it makes a nice big
table. Holds the Ambo up with a foot or so workspace on each side. Perfect.
This is a response after postin to another list.

Hi, everyone. Had to reply to this as I feel some of the recommendations in the replies about bike lifts, are in themselves, possibly dangerous. Grade 8 bolts are certainly harder than grade 5, or lesser, and have a greater tensile strength, but I have always been led to believe that grade 5 bolts possess a higher shear strength than grade 8. It seems to me that the failed bolts described, would be in shear, rather than tension. If these bolts form the pivot in a scissor arm arrangement, it is also important to keep the arms as close together as possible, to reduce the twisting of the bolt in the pivot hole. This increases the shear factor substantially, if the bolt is allowed to twist. Use loctite and double locknuts on them if this is the case. These thoughts come from 20+ years in the spanner game, but I am the first to say check with an engineer, if in doubt. Regards, Eddie. __________________________________________________ Do You Yahoo!? Yahoo!
