I never have , and I'm curios ! http://www.allischalmers.com/new/forum/forum_posts.asp?TID=28600&title=ac-attachment
Yes I have. There's one parked just down the road from me, mounted on a TD14. I think the idea was to have an attachment on a cat that could load a truck too. From what I've heard, they weren't that great. You ended up with more dirt in your lap than anywhere else.
THeres one not too far from here its an old Eimco. Got a 4 cyliner Detroit behind te cab and sits one smoot tracks. Its got the machine chain pulled rocker arms. Ballew and Roberts Paving had it loading thier hot mix plant. My old friend HW Fredrick told me that when they bought mix from them that they saw it alot. He said one day they had a Caterpillar salesman come by to sell them a brand new 922 Cat wheel loader remember ths was years ago when everyone here used track loaders. He said they made a deal that if the 922 loader would be bought. THe bins were directly infront of the mixing conveyor and the little Eimco out loaded 922. THey had their place as they had another one that was used loading shot rock on road additions where trucks had to be backed in to the tractor for loading.
Theyre called over shot loaders, belive it or not when you bought a crawler back in the day all you ever got was a basic machine without a dozer or a bucket. These are just one of the cool inventions that got mounted on a factory machine. My grandfather had a d2 with a loader on it like that and the only thing he didnt like was that you would get a real headache unless you had a steel plate over the cab.
Yair...we called them overloaders here in Australia. They were pretty common up untill the late 'sixtys. They were mounted on all makes of tractor...I never saw them on anything much bigger than a six. A lot of councils had them and they worked okay at loading gravel. They took the place of a "chinaman" loader at a lot of pits. Out of curiosity did you blokes use chinamen in the 'States? They were just an angled chute high enough for the trucks to drive under and a D6 or whatever just pushed the gravel up and into the trucks. There is no faster way of loading and I notice a couple of years back there was an outfit loading four trailer side tip trains with a skid mounted one over in the Kimberly. It was pretty elaborate setup, the trucks drove under and they had a grissly to scalp the oversize as the load fell in the truck.
Thats a Sargeant overhead loader,the truck parked right behind the tractor,they went straight into the bank,and then backed up to the truck. Cletrac did use a bunch of them,i had one once on a BG cletrac. Don
I saw a similar type of loader at the Historical Construction Equipment show in CT. a couple of years ago . It was mounted on a rubber tired tractor and the digging end was the rear of the tractor , it looked like you could be killed pretty easily as the loader arms were inches from the operator as they traveled from the rear dig position to the front dump position ! It was interesting but scary to watch work. If I ever see it again I'll take some pictures and post them here. Tom
I learnt to operate on a similar type machine mounted on an IH TD9 back in NZ in the 60s. They were called an over head loader and were mostly mounted on IH TD 6s & 9s, on them the bucket could dropped off and the blade put on in a few minutes and were good for pushing over trees as you had plenty of lift on the blade as well when the bucket was on there was no turning the machine to dump , just put the truck behind you and it was just back and forward, load and dump.
