Atlas ATEATTC-LHA Pneumatic Left-Hand Assist Arm for 200/700 Series Tire Changers

Description

The Atlas ATEATTC-LHA is a pneumatic left-hand assist arm that bolts onto the column of an Atlas 200 Series or 700 Series tire changer. It adds two working heads to the technician's reach — a bead lifting disc that pushes the lower bead up into the wheel cavity, and a bead pressing block that holds the upper bead seated below the rim edge during the rotation pass.

The point of the assist arm is controlled force. On stiff sidewall, run-flat, and low-profile tires the bead resists going where leverage and a tire bar alone can no longer take it. The pneumatic arm applies that force consistently — spec'd to mount and demount today's tougher tires while reducing the rim damage and technician strain that come with brute-force technique.

Components

Bead Lifting Disc

The lifting disc presses up against the lower sidewall, applying controlled pneumatic pressure that forces the lower bead up into the wheel cavity so the tire can release on a tough demount. Without it, a stiff-sidewall or low-profile tire often locks the bead against the drop center and refuses to walk off the rim.

Bead Pressing Block

The pressing block applies controlled downward pressure on the upper sidewall, keeping the bead seated below the rim edge as the wheel rotates against the mount/demount head. The block geometry is shaped to ride on the tire shoulder rather than the alloy.
