Excessive Horizontal Clearance of Tire Changer Arm Causes Hub Scratches, Roadbuck Multi-limiting Structure Guarantees Pr

Many mechanics think rim scratches are caused by deformed mounting heads, yet the real problem lies in oversize horizontal gaps of pull-push arms. Long-term operation wears parts and shifts the working head during tire service.

Roadbuck uses heat-treated Q235B high-strength steel for vertical and pull arms, with adjustable clearance structure on six-square rods to offset wear tolerance. The column base is fully welded to the cabinet without loose screws, and the main column rotating shaft adopts limit rings to eliminate root shaking.

All V9120, V7110 and GT525 tire changers adopt this multi-layer limiting design. Strict verticality inspection restricts mounting head horizontal displacement within 3mm to prevent tire cutting and hub abrasion. With 20 years of manufacturing experience, Roadbuck solves structural defects from the design stage.
