CR11 Roller & Idler Rebuilder

WTC Machinery's CR-11 Roller Idler Rebuilder is the modern, efficient way to rebuild worn idlers and rollers. The two high amperage weld heads come complete with power sources, and assure high deposition rates with both circumferential (stringer) and oscillate (cross) welding methods.

The standard power yoke tilt handles flange welding and the simple, straight-forward controls guarantee easy operator training. The high capacity wire holders, flux hopper and included flux recovery system provide uninterrupted welding for the biggest jobs.

The optional Jib Crane, "J" Hooks and Lifting Tongs allow the CR-11 to work without forklifts or building cranes, and the optional Water System avoids bore shrinkage when welding assembled rollers.

Why is the dual head CR11 so efficient?

  • Efficiency
    • Two heads are better than one.  Gets the job done in half the time.
  • Head Control
    • With different head control options the service style is up to you
  • Automatic Flux Recovery
  • 45 Degree tilt for inner welding

Watering Cooling System (Optional)

Used in roller service, the Water Cooling System transfers heat from the roller currently being welded to the next roller to be welded. This eliminates bore shrinkage, and shortens pre-heat time. The included Adapter Kit allows use with most undercarriage types.
