CRANK: Adjustable Idler Assembly CRANK: Adjustable Idler Assembly

The sprockets for the system are mounted on a side track to keep proper tension on chain. This setup prevents the chain from slipping and also makes chain adjustment simple and cost effective.

The system comes with a #40 steel chain and a stainless steel chain is available as an option.

For the Tarpco Crank System, several options are available for the rear of the trailer.

We have optional two piece tail assemblies available. In this setup, the trailer is completely sealed and diverts water from the back end of the trailer. The back end is sealed for state jobs. With this setup, the back of the tarp slides together and overlaps the end flap.
