Mining trucks are slow. But even slower are the tracked vehicles that fill them, designed as they are to move very heavy things very short distances.

Which means if you need to relocate an enormous bulldozer or tracked excavator to the other end of the mine, you’d better clear your schedule for the next few weeks.

Which is where this curious machine comes in. Effectively a Komatsu mining truck with a gooseneck hitch in place of the dump body, it can tow the aforementioned mining machines to their new location aboard a specially-designed single-axle TowHaul Lowboy trailer, capable of transporting 250 tons. We bet parking isn’t fun.

This spectacular fully remote controlled recreation of the world’s biggest vehicular trailer comes from previous bloggee Beat Felber, whose converted Komatsu HD785-5 mining truck features motorised drive, steering, and gooseneck hitch, enabling the model to load and tow a huge TowHaul Lowboy trailer and its Komatsu D575A-3 ‘Super Dozer’ load.

There’s loads more to see of the both the Komatsu HD785-5 truck and the TowHaul Lowboy 250 ton trailer behind it at Beat’s Flickr album, and you can watch the whole rig in action courtesy of the video below.
