dump bed lift question

[chester]

Would anyone be able to direct me to some details on the dump bed raising device on this truck?

[Ray Dunakin]

Cute truck, with that boxy wooden cab! Would definitely be fun to model.

Unfortunately, I can't answer your question regarding the dump mechanism.

Can't really help much,
It looks like a version of the PTO lift that was used by several manufacturers in the 20's.  Dump beds and their lift units were almost always after market units and not OEM.

Interesting. Have unfortunately never seen it before.

Inclined to agree with Rick , looks like a chain driven hoist powered by a Mid mounted PTO

A lot of these were built by "Highway Hoist"  who I believe continued to major suppliers of mechanical  hoists even after people like "Heil" had moved away from mechanical to hydraulic power.

Would highly recommend the book  Dump Trucks  by Donald F Wooding in the Crestline series published by MBI Publishing Company ,   ISBN 0-7603-0867-5
(Type in Abe books in your search engine, and then the ISBN number there are number available in the States)

You will find all sorts of things in there you will want model

Gordon seems to be on the right track.   According to this review in Google books, Page 44 shows a similar hoist. http://books.google.com/books?id=gQ7tJI_3t30C&pg=PA41&dq=dump+truck+highway+hoist+company&hl=en&sa=X&ei=Mq-kUZD_Cebq0AHu1oHoCg&ved=0CEoQ6AEwAw#v=onepage&q=dump%20truck%20highway%20hoist%20company&f=false

Thanks all, will have to buy some books on the subject. Good link to that one in particular. I believe the truck in the photo is an Oldsmobile by the way. Thanks again.

Ended up copying a gear driven unit I had some photos of in a pretty crude way but from a few feet away this scale can be somewhat convincing. The curved gear is merely corrugated roofing cut into thin strips. The truck is a 1929 Autocar 'Dispatch', a 2 ton, 60 hp. six cyl. they built until 1935. The 'big brother' of this truck was called the 'Ranger' that had a 90 hp rated engine with beefier tranny and rear as well as the more obvious differences of 10 lug wheels, larger rad and split windshield. The Ranger was weight rated up to 5 tons.

I echo the others.

Nice!
sits in its context convincingly

at a tangent,
whats the building in the background?
its got interesting arches,  brick?, special shapes brick or corbelled out?

Thank you all. Don, that is a Railway Design Associates injected plastic structure in brick that I covered in plaster. The platform is scratch built.
