Thank you Jorge, for your kind comment. Researching, designing, component sourcing, building and documenting this model of a 1960s vintage P&H model 1015 crawler mounted crane was a passion I pursued for many years, and your positive comment makes the project that much more rewarding for me. Best Regards, Tom Garing
@@cranemodelbuild3236 Thank you for bringing back some great memories. My very first job was at 16 years old being the Oiler on an old Marion Dragline digging out limestone from a huge lake in Pembroke Pines, Florida. Unfortunately I do not remember the model number but I do remember it was a crawler and it was massive. This was 24 years ago and it was considered a dinosaurs back then. She was being outpaced by the newer Manitowoc 4600's. My uncle was the operator and he would let me at the controls when the bosses were gone for the day. She was old but still functional and had nothing but raw power. Man I loved her so much. This was before everyone had a camera in their pocket so I don't have any pictures at all. I've desperately searched online for years of at least a picture of her but nothing. The only images or videos of Marion Draglines that I've been able to find online are walkers, but my baby was definitely a crawler. I wish I could see her one more time. Thank you for your video again. It doesn't do any justice to the amount of work I know went in to everything you did.
@@jorgemercado7505 Jorge, thanks for sharing your history of Dragline work. Was the Marion you worked on a model 183-M? If so here is a link to a you tube video on one of few remaining in existence: th-cam.com/video/uCKJJMIrL04/w-d-xo.html Hope you enjoy it. Best Regards, Tom
Thanks Cuz Kenny, it certainly keeps me busy. Going forward I may start to post on various aspects of the build and may even offer the 197 pdf drawings, 16 page excel Bill of Materials, 35 page Owner's Manual and 2,700 jpg construction photos for sale on a flash drive, we'll see. Stay well Cuz, Tom
Sorry, accidentally clicked "add comment" before done. The dragline bucket "chains" were made from lamp "pull-chain" & the dump "cable" was heave nylon string. There may be some details about this dragline model I've forgotten, but I think I've included the main details. My Dad built this model in the early 1970's, over a few months, it seems. He was a Professor of Mechanical Engineering. The model was intended for a kid of 8-10 years old or so, to sit on the model's roof & operate the controls, which I did with much enjoyment! Dad wanted to make a "walking" dragline feature for the model, which I'm sure he could have, but he never had the time, or lost interest in that project. Seeing your beautifully crafted crane & dragline bucket reminded me of the model my Dad made, so I thought it might be an interesting story to share with you. As for the dragline model, my oldest brother got it some time ago, & I don't know what's become of it since then. Cheers!
Shadowvanish, WOW, what a detailed recollection you have of your Dad’s dragline model. Sounds like he was quit a creative guy. I too am a degree Mechanical Engineer who spent most of my career in manufacturing, but my favorite professional memories were when I started my career in the early 1970s as a machine designer. I actually started designing my model in 1971, around the same rime your Dad started working on his model. Also like your Dad’s model, I use automotive windshield wiper motors as the motors for the three hoist drums and the swing drive. Originally I too had plans on an umbilical cord for power before I started having kids and packed the project up until I retired and restarted the project 6 years ago. Where about do you live, and are you into modeling? Thanks for your comments and interesting story. I would love to see pictures of your Dad’s work if you ever come by any. Stay well and subscribe to my channel. Regards, Tom Garing D’Souza
Very nice work! I've been fascinated with dragline models for years. My Dad built a dragline crane model years ago that was functional & semi-scaled to a very large mining dragline (can't recall the mfg.; Bucyrus Erie possibly) used in the same coal mine that the "Big Brutus" Bucyrus Erie 1850-B electric shovel worked in (which I was fortunate enough to see in operation, during a visit to the mine). Anyway, the model used 3 12 volt DC automotive motors with gearboxes to operate the swing, drag & hoist functions. 120 volts AC entered the model from the underside of the lower structure, & was rectified & reduced to 12 volts DC through a step down transformer. Slip rings & brushes, located between (& at the center of rotation of) the lower & upper structure, were used to transfer the power into the model's upper structure interior, & power the 3 motors. My dad fabricated the latice boom from formed sheet metal strips (I'm guessing 20 gauge sheet steel), & spot welded the boom pieces together. The boom was about 5 feet long, as I recall, & had a 12 volt work light built into the underside, at the mid point of the boom's length. The crane's "house" was fabricated from 3/8" plywood (I think) & the "house" roof was made from a rolled piece of galvanized sheet steel. The boom could be raised & lowered using a machined aluminum hand crank connected to a worm gear drive that operated the boom hoist drum, which was part of "A-frame" or gantry structure (also fabricated from sheet steel) located on top of, & at the front of the "house's" roof. The "A-frame" also contained three toggle switches for motor operation. Near the top end of the boom's upper side, a single sheave pulley block was used for the hoist "cable", which was heavy nylon sting. A "master" on-off switch was located on the side of the "house" & a small cooling fan was mounted in an opening at the upper rear of the house for ventilation (like the full scale machines). The turntable used marbles for ball bearings, & Dad made upper & lower bearing races out of bakelite, (I think, but it might have been a different material), into which he machined bearing race grooves for the marbles to ride in. And, he made a semi-scaled dragline bucket that was about 1/2 the size of the one you made, as I recall, from approx 16 gauge sheet steel. The bucket "chains" were made from "pull chain" type
