The prototype for this diesel-electric crane dates to the mid-1950s. These 25- to 30-ton capacity locomotive cranes are self-propelled and capable of moving several gondolas at slow speeds. The movement capability was important, as it allowed the crane to get out of the way for passing trains.
Railroads depend on these machines to do all sorts of moderate lifting jobs. The model crane came fitted with a hook, and the real crane can swap tools to work with a clamshell bucket or an electromagnet depending upon the job.
I wasn’t able to find a drawing, but the model does match typical American Hoist Co. dimensions for these cranes. The chassis is 10′-0″ wide, 24′-0″ long, and has a deck height of 3′-6″. The cab is 18′-0″ long and stands 15′-3″ above the railheads. The boom is 51′-6″ long.
The model has a heavy die-cast metal chassis that rides on acetal plastic Association of American Railroads trucks fitted with RP-25 contour metal wheelsets that match the National Model Railroad Association gauge. The crane has split axles and internal contacts so it picks up current with all eight wheels.
A small motor inside the cab drives a crown gear mounted on the cab kingpin. The kingpin passes through the floor to drive a helical gear train and pair of worms. Only the two inner axles are powered (which matches the prototype). There’s room inside the cab to add a Digital Command Control (DCC) decoder. The crane’s cab can be manually rotated 90 degrees to either side.
The sample crane started and ran smoothly on a regular DC power pack. It can easily move 2 or 3 loaded gondolas.
This model came neatly painted with a bright yellow cab for visibility. The Pennsylvania keystone herald and raised “American” lettering across the back of the counterweight were straight and crisply printed.
This model can be used on any diesel-era railroad work train, and it’ll fit right in on many heavy industrial jobs in power plants, scrap yards, or steel mills.
