Crane Model Build

I have, for many years, been interested in crawler mounted cranes and, over the last fifty plus years, have collected information on a 1960s vintage 110 ton capacity P&H model 1015 crawler mounted crane that I have recently completed designing, building and documenting as a fully operational RC scale Crane Model. Here is a brief description of my project along with several photos of my finished model and a URL link to my Crane Model Build You Tube Channel’s Playlist.

This Crane Model is a 1/12th scale full functioning 8 channel Radio Controlled replica of the P & H Model 1015 Lattice Boom Crawler Mounted Crane. Power for the model is provided by a 12 Volt, 22 Amp/Hr LiFePO4 battery that is mounted at the right rear of the cab. The model’s left and right crawler treads are powered independently with 12 Volt gearmotors and propel the model at a scale speed of 60” per minute. The single Boom Hoist Drum, two Cable Hoist Drums and the Cab Swing are each powered by modified 12 V windshield wiper (worm gear) motors from late model VWs. The lattice boom is a hybrid design that utilizes select straight 5/16” dia oak x 36” long corner rods with 1/8” dia poplar lattice members, however the boom areas of stress concentration including the Boom Tip section, Boom End sections and the Boom Base section are 50/50 soldered brass tubing fabrications.

While a lot of my “build time” was spent in the design and documentation of over 117 pdf two view engineered drawings for all of the individual components, the creation of a 66 page Owner’s Manual and the capture of over 2,600 jpg construction photos, I would estimate the time required for an average hobby machinist to build the model to be around 1,200 to 1,500 hours. Note that access to, and knowledge of both a metal lathe (7” Swing Over Bed x 16” Distance Between Centers min) and mill (15” x 7.5” table travel min) are required.

Thanks for your time and interest in my model,

Wow that's awesome craftsmanship!

Absolutely great fantastic work. Detailed & functional. Wow just wow. I'm a machinist for 30 years now, done fabrication & welding, even a little blacksmithing. I know what it takes to build comprehensive machines. Hats off my man. Very cool. Do you take it to shows or state fairs?

332_RC,
I was just reviewing the thread and could not see where I had replied to your kind comments. So a big thanks to you for them! Yes I have shown it at a local Maker Faire and a regional RC fest, but that's about it. Yes, I try to make it clear to anyone wanting to purchase my plans,
that at least bench top machining equipment and skills are a large part of the requirements for this build.
BEST,
Tom

This is awesome looking. But now for the real question... can it land a fish?
