Using a U-shaped carriage, under the same specifications, the volume inside the carriage increases by 10.5%, while the body weight decreases by 1.3% and the center of gravity of the cargo decreases.

Lightweight carriage design, with multiple bends on the carriage side panels of the same specifications, increasing the strength of the side panels.

The integrated design of the main beam greatly improves the load-bearing performance of the main beam.

Adding a funnel structure at the tail makes it convenient to work with other machines.

The motor moves backwards and the center of gravity of the cargo moves towards the rear, increasing the stability of the vehicle when carrying cargo.

Add a locking mechanism to the rear door to make it more stable to open and close.
