14 mm thick hub chuck assembly with fine-adjustment function for chuck opening/closing dimensions. The chuck jaws can be precisely controlled at any position, enabling secure wheel clamping and preventing accidental damage.
The foot-operated pneumatic valve piston rod assembly is constructed from S304 stainless steel, featuring a smooth surface with excellent corrosion resistance for extended service life. The drawer-style control unit has a simple structure, enabling quick and convenient maintenance and repair.


Top quality aluminum motor with all-copper windings delivers superior heat dissipation, reduced energy loss, and high power output. The 180mm diameter dual-inlet bead breaker cylinder features a fully sealed design, operates efficiently even at low air pressure, and ensures extended service life.

The modular casing is constructed from CNC-formed steel panels and robot-welded with concealed seams for a sleek appearance.

The tower-style column base and casing are constructed with fully integrated welding, ensuring exceptional load-bearing capacity, structural stability, and reliability during high-intensity operations. A tapered bushing with bi-directional locking mechanism prevents long-term loosening.
The rear-tilting upright arm design creates expanded operational space above the hub chuck, preventing accidental damage during wheel clamping. The sliding roller mechanism incorporates a 55 x 55mm square steel push-pull arm with CNC precision grinding, maintaining unilateral clearance under 0.5mm. This ensures the pry head displacement remains within 3mm during tire mounting/demounting operations.


The dual press bars and single tire press crank design provide multi-point tire pressing assistance during mounting operations. The low-position tray supports tire lifting during demounting. An integrated lifting slide rail with fine-tuning capability ensures smooth and stable vertical movement, delivering higher efficiency and superior usability.
