Caseload

This is a fully remote controlled Case QuadTrac 620, built by mktechniccreations, and it’s really very good at squashing Elves. It’s also one heck of a build, with no less than six Power Functions motors, two BuWizz bluetooth batteries, and a pneumatic system with on-board compressors. And that’s before we get to the Elmer HaulMaster 2000 trailer.

Back to the Case, where two L Motors drive the fully suspended tracks, whilst a Servo articulates the pivot steering (the rear section of which can also oscillate independently from the front to keep the vehicle level on uneven ground).

Two M Motors power the on-board pneumatic compressors/switches, a third drives the rear PTO, there’s a suspended cab, swing-out ladder (that automatically pivots out of the way of the tracks when the tractor articulates), a rotating driver’s seat, and pneumatically operated hitches.

The Elmer HaulMaster trailer features a few trick of its own too, with the Case’s PTO driving the conveyor belt and auger worm-gear, pneumatically operated auger boom extension, and pneumatically deployed support legs.

It’s an unfathomably complex and wonderfully engineered build, and there’s lots more to see of mktechniccreations’ incredible creation at the Eurobricks forum via the link above, where complete technical details, further imagery, and a link to building instructions can be found.
