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.

Crank: Rear Options

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. The tailpiece is mounted & the rear door swings with it.

Crank: Standard Front Bar

1" solid front bar, keyway on ends.
4 greaseable pillow blocks mounted out toward ends for strength. Stops bar ends from bending back under normal cable pressure.
Solid pulleys and chain sprocket.
Solid aluminum airdamn (optional).

Crank: Radius Leveling Kit Option

This option allows for maximum loading space.
Prevents loading damage.
Squares off front radius on dump trailers so that the front bar can be mounted outside the trailers.

Crank: Optional Electric Motor

We have two styles of motors available: sealed and non-sealed.
Either style powered by 6-2 wire ran through the bulkhead and down main body.
Wires ran using rubber grommets inline fuses to prevent overload and damage to the system.
Heavy duty rotary switch is conveniently mounted in the cab.
