Bucket-Wheel Stacker Reclaimer 1:200 - Hand-Cranked Slew, Luff and Wheel

Free 1:200 version of a hand-cranked bucket-wheel stacker reclaimer. Three hand-operated movements: a crank with a 14-tooth pinion and a compound 28/10-tooth shaft walks round a fixed 40-tooth ring to slew the whole machine (8 crank turns make 360 degrees); a thumb wheel and rack luff the Warren-truss boom from -12 to +28 degrees; and a crank at the boom head spins the 12-bucket wheel.

WHAT IS IN THE DOWNLOAD

• 27 STL files for the 1:200 scale, one file per part, ready to slice. About 158 x 84 x 70 mm.

PRINT NOTES

• The whole set was slice-checked in PrusaSlicer (0.4 mm nozzle, 0.2 mm layers): no failed parts and no supports needed; some small parts use a brim. About 61 g and 6 h, by the slicer estimate.

• - The moving parts were checked in a simulation (1413 positions, no interference, 0.34 mm running clearance).

• - Known limits: the slew uses a spur gear reduction (not a worm gear), the wheel crank is direct, the boom is a stylised plate truss, and the deck and boom are held by friction.

• - The model has not been test-printed yet. The images are renders, not photos; the coal pile in the images is not part of the files.
