The Atlas ATEATTC-RHA is a pneumatic right-hand assist arm built specifically for the Atlas 700 Series tilt-back tire changers. It is the tool a high-volume tire shop adds when run-flat sidewalls and low-profile passenger tires start eating manual mount and demount time. The arm carries its own toggle control valve, so the operator first positions the attachments at the correct working height, then applies air pressure to push the bead onto or off the rim — no fighting the sidewall by hand.
The RHA is engineered as the right-side counterpart to the Atlas LHA (left-hand assist arm). When both arms are mounted on the same 700 Series machine, the operator has assist on both sides of the wheel for the toughest sidewall and bead seats — useful in shops that regularly service modern OE wheels where stiff run-flat construction has become the norm.
What's included
Pressing / pulling disc — works the bead on or off the rim with controlled air force
Bead roller — holds the sidewall down while the turntable rotates
Toggle control valve — dedicated pneumatic control for the right-hand arm
The three primary control points on the RHA: Right Arm Control, Bead Roller, and Bead Lifting Disc.
The assist arm operates entirely on shop air; the host 700 Series machine supplies the air through its own regulator and oiler. There is no separate electrical hookup for the RHA itself.
Bead roller engaged on a mounted tire — keeps the sidewall down while the turntable rotates.
Please note that if you order an Atlas item, your delivery location must be able to accommodate a 53' truck. The RHA ships at 169 lbs.
