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.
