It adds two working heads: a \u003cstrong\u003ebead lifting disc\u003c\/strong\u003e that pushes the lower bead up into the wheel cavity during demounting, and a \u003cstrong\u003ebead pressing block\u003c\/strong\u003e that holds the upper bead seated below the rim edge during the rotation pass. Both heads apply \u003cstrong\u003econsistent pneumatic force\u003c\/strong\u003e rather than manual leverage — the difference that prevents the rim contact and technician strain that come with forcing a resistant bead by hand.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe LHA is the right upgrade for \u003cstrong\u003eAtlas 200 or 700 Series owners\u003c\/strong\u003e whose changer is mechanically sound but increasingly underpowered for the run-flat and low-profile fitments that now make up a growing share of the vehicle mix. Adding the assist arm extends the machine's capability without a full changer replacement. For shops that need both sides covered, the LHA pairs with the \u003cstrong\u003eAtlas ATEATTC-RHA right-hand assist arm\u003c\/strong\u003e to form a complete dual assist arm setup.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePneumatic left-hand assist arm for controlled, effortless tire handling\u003c\/li\u003e\n\u003cli\u003eCompatible with Atlas 200 Series and Atlas 700 Series tire changers\u003c\/li\u003e\n\u003cli\u003eBead lifting disc included\u003c\/li\u003e\n\u003cli\u003eBead pressing block included\u003c\/li\u003e\n\u003cli\u003eDesigned for run-flat and low-profile tires\u003c\/li\u003e\n\u003cli\u003eReduces rim damage and technician strain when working with stiff sidewall tires\u003c\/li\u003e\n\u003cli\u003eShipping weight: 160 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cfigure\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0771\/5550\/0318\/files\/atlas-ateattc-lha-left-hand-assist-arm-feature.jpg?v=1778256348\"\u003e\u003c\/figure\u003e\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.
