The Atlas® DAA is the combination of the Atlas® LH assist arm and the Atlas® RH assist arm. When you buy these two arms at the same time, you save money.

TThe Atlas® LH assist arm is designed to be mounted on the Atlas® TC755 wheel clamp tire changer. The pneumatic powered LH assist arm is a must have accessory to mount and demount many of the stiff sidewall tires found on today's vehicles. This Atlas® LH assist arm provides robotic power, allowing the operator to keep both hands free during the tire changing operation. The disc and rotating press arm exert an enormous amount of pressure on the sidewall of the tire so the operator can mount or demount a stiff sidewall tire.

The pneumatic power cylinder produces sufficient power to allow the properly positioned pressure disc to exert both upward and downward pressure (depending if you are mounting or demounting) on the sidewall of the tire. You must exert enough (upward or downward) pressure on the tire's sidewall to effectively move the bead of the tire close to the center of the rim. Many of the cheaper arm assemblies are no more than an air cylinder mounted above the turntable. These low cost air cylinder arm assemblies exert only a minimal amount of downward pressure. This downward pressure is needed for mounting the tire on the wheel, but is ineffective when you need to dismount the tire from the wheel. The lifting disc of the Atlas® LH assist arm exerts an enormous amount of controlled pressure to gently force the lower bead up into the wheel cavity, so that the tire can be removed. The bead is held below the lip of the rim by the rotating bead press adapter as the tire is being mounted.

The control toggle switch is positioned for maximum accessibility and ease of use.

The Atlas® LH assist arm may be purchased at the same time you purchase your Atlas® TC755wheel clamp tire changer, or you can purchase an Atlas® tire changer now; and add the Atlas® LH assist arm at a later date.

The Atlas® RH assist arm. is the perfect complement to the Atlas® LH assist arm when you need to change extremely stiff sidewall and run flat tires. As the old saying goes "two hands (heads?) are better than one". The addition of the Atlas® RH assist arm (in conjunction with the Atlas® LH assist arm) provides unparalleled power to mount and demount the most stubborn tires.

The Atlas® RH assist arm has a separate toggle control valve that allows the operator to position the arm assembly to the correct height and then move the attachments (up or down) by applying air pressure and forcing the stiff sidewall part of the tire either on the rim or off the rim.

The oversized polyurethane bead roller moves easily across the horizontal slides to the correct position over the bead of the tire. This bead roller exerts a downward pressure on the bead so the bead stays below the rim lip as it passes over the mount/demount head.

Hose connections are well marked and the hoses are enclosed in a protective cover to prevent damage.

The Atlas® RH assist arm and the Atlas® LH assist arm are the perfect combination to change just about any run flat or stiff sidewall tire.
