Bellows to protect the cold chain

BELLOWS TO PROTECT THE COLD CHAIN

If a box truck together with trailer drives up to a loading ramp in reverse, it can be completely loaded and unloaded without the driver having to uncouple the trailer. With refrigerated vehicles, the weak point is the transition between the trailer and the motor vehicle, because at this point the cold can escape through the open end walls, so that the cold chain is interrupted. The maintenance of the cold chain is ensured by attaching a bellows. The bellows is concealed inside a rubber lip and is only extended pneumatically during the loading process. During travel, the bellows are completely protected by the enclosure.

The patented system was first presented by Schwarzmüller at the MAN Roadshow in Munich.
