Plans, P&H 1015 Crane Model - 1/12th Scale

This Crane Model is a 1/12th scale, fully functioning 8-channel Radio Controlled replica of the 1960s vintage P&H Model 1015 (110-ton capacity) Lattice Boom Crawler Mounted Crane. Power for the model is provided by a 12 Volt, 22 Amp Hour 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 inches 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” diameter oak x 36” long corner rods with 1/8” diameter 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 time was spent in the design and documentation of over 117 two-view engineered drawings for all of the components, (with many of the sketches augmented with step-by-step Word instructions) I would estimate the time required for an average hobby machinist to fabricate the model from the Crane model 1015 DIY Flash Drive plans to be around 1,200 to 1500 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.

The Crane Model 1015 DIY Flash Drive stores over 7 GB of digital information including, 117 PDF Sketches and Instructions, over 2,600 construction photos cataloged in 53 folders for easy reference, a 21-page Excel Bill of Materials that lists the part numbers, the sketch numbers and required materials/hardware, electrical wiring diagrams, radio programing instructions, full size crane photos/brochures and a 66-page Owner’s Manual.
