Atlas Left (LH) Assist Arm

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 thecenter 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.
