It adds two working heads to the technician's reach — a \u003cstrong\u003ebead lifting disc\u003c\/strong\u003e that pushes the lower bead up into the wheel cavity, and a \u003cstrong\u003ebead pressing block\u003c\/strong\u003e that holds the upper bead seated below the rim edge during the rotation pass.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eComponents\u003c\/h3\u003e\n\u003cfigure\u003e\n  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0771\/5550\/0318\/files\/atlas-ateattc-lha-left-hand-assist-arm-feature.jpg?v=1778256348\" alt=\"Atlas ATEATTC-LHA assist arm with left arm control, bead pressing block, and bead lifting disc labeled in operating position\"\u003e\n  \u003cfigcaption\u003eLeft arm control, bead pressing block, and bead lifting disc.\u003c\/figcaption\u003e\n\u003c\/figure\u003e\n\n\u003ch3\u003eBead Lifting Disc\u003c\/h3\u003e\n\u003cp\u003eThe 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.
