All, i'm new on this form and i'm new with V-slot. I'm wondering what would be the lifting power of a V-slot system based up on a 80 x 20 x 1.000 mm V-slot rail and helix as possioner? Is this capable of lifting approx 15 to 20 kg only 3 times per day? If so, how long will it last? look forward to see some feedback. Regards, Robert
