6346 Uni-Tred Space Hauler


Click to Enlarge


The Uni-Tred Space Hauler is a single tread vehicle that held a couple of figures in a red enclosure located on top. The vehicle could be dissembled into three parts and re-assembled in a few combination. The unique gearing of the Uni-Tred enabled it to pull the Space Bubble over obsticles at a fairly high rate of speed. A middle tier (called simply "white supply base" in the instructions) could be withdrawn from the Uni-Tred and used to haul cargo (two rubber-band stays allowed cargo to be sturdily tied-down to the platform without flying off as the Uni-Tred traversed heavy terrain).

The Uni-Tred has an interesting front grill-like feature that seems out of place in context with the no-atmosphere moon. In all, still a very cool vehicle and a staple in the MMM collection.

Variations: John's Notes:
It's interesting that the 6339 Uni-Tred and Space Bubble set actually has an earlier Stock Number. I think this was originally intended as a combination set, and later split up into each component. Designs appear to be from a caterpillar-style construction vehicle such as a bulldozer or tank. This is a unique vehicle and does not appear to be based on any actual space designs.
