WALL-E transport vehicles are transportation trucks built by the Buy n Large corporation for Operation Cleanup. They are used to transport and store WALL-E (Waste Allocation Load Lifter: Earth class) trash compactor units. These trucks have two large wheels at the front and tank treads at the back, which allow them to move across difficult terrain. These trucks have a single exhaust pipe. Inside the truck's cargo storage area are rotating shelves for storing WALL-Es. The truck is used for moving WALL-E's from place to place after they finished cleaning an area. It is also probably used to store them at night when they are inactive.
The last active WALL-E unit still uses one of these trucks as his home after 700 years. Because the other WALL-E's are no longer active and not in the truck, there is a lot of free space inside. WALL-E has placed all the interesting items he has found from the mountains of trash inside the truck.
The truck gets damaged twice during the movie by EVE. When WALL•E tries to teach EVE to dance, she accidentally knocks WALL-E into a wall of the truck damaging both WALL-E and the truck. The second time is when she blasts a hole in the ceiling of the truck after she finishes repairing WALL-E to allow him to regain light for a recharge. Near the end of the film, PR-T puts powder on the same truck.
The truck contains rougly 1,000 unique props, which a team of five modelers and five shading artists took over a month to create.
