My wife and I once carried my new Super 7 upstairs to my back bedroom workshop,with just the motor and tailstock removed,though it was 40 odd years ago. Recently I sold my J & S 540 grinder ,handbook weight 750 kilo grammes,the purchaser sent along two of his chaps,nice blokes and were they strong, they moved the grinder across the workshop floor on rollers which is easy until they got to the 2 inch drop in the floor, they asked if I had a good pallet which I did have,it has a 19mm ply top face , the two of them then tilted the machine backwards to its point of balance,one bloke held it while the other slid the pallet under it as far as it would go,then both of them tilted the machine forward onto the edge of the pallet ,and then pushed ,lifted and skidded it on to the pallet,all done in a few minutes,never seen anything like it ,when I installed the machine years ago it took me on my own half a morning too get it up the step with a chain hoist and packing and rollers,they then moved it easily outside on a pallet truck, then their crane lorry turned up it was so easy to load ,the crane could lift 8 tons at 7.5 metre radius,the the driver took the eight wheeler out of yard ,along the drive and out the gate without touching the lawn or gate posts, brilliant job.Couriers with transit vans make more mess and run over the drive edges.Over the years I have moved stationary engines up to 2 ton and installed a lot of machines in my workshop a lot of it on my own,and have acquired a lot of kit to move things as I have found it is best to wheel and roll heavy items and avoid manual lifting as it can all to often cause back injury,one of my really useful items is a couple of lengths of conveyor with rollers,these were use in an apple packing shed and the apple boxes rolled along on lengths of conveyor, the side frames were 2 inch angle with steel rollers about 16 inches long,I cut the them down to make a frame with 6 rollers,then turn them upside down so the rollers are on the ground and the frame with some extra angle welded on carry the load,a pair will carry well over a ton,they cost nothing and have been used to move machine tools,heavy stationary engines,etc if the grounds rough then lay down scaffold planks or plywood.
