Self-loading PT-12 bale semi-trailer, Kharkiv region.

Principle of operation:
picking up and loading is carried out by a fork lifter, which, with the help of a hydraulic cylinder, lifts the bale onto the platform. The front wall moves the bale backwards. When transporting to the skirty, unloading is carried out by shifting the bales along the front wall, through the rear hydraulically opening board. The bales slide easily along the guides, keeping their shape and integrity.

The chain conveyor is located in a closed niche, which completely excludes contact of the chain with the bales and damage to the threads.

Aggregated with tractors: MTZ, YuMZ.

The semi-trailer bale loader is used for picking up, transporting and unloading bales.
