Xintuo 420 Hot-DIP Galvanized Wheeled Boat Trailer/Jetski Trailer

The core advantage of the Model 420 double-row wheel trailer lies in its innovative double-row staggered roller layout. Through increased quantity and scientific distribution, it achieves a dual breakthrough in load-bearing capacity and stability. Each row of rollers is made of high-toughness engineering plastic and paired with thickened metal bearings, increasing the load-bearing capacity of a single wheel to 60kg.

The 12-16 rollers in total (adapted to trailer size) create a uniform force-bearing surface, allowing for an overall load capacity of 450kg. Structurally, the staggered arrangement of the double-row rollers not only expands the contact area with the bottom of the motorboat but also distributes localized pressure through "relay," preventing uneven stress on the trailer caused by the motorboat's center of gravity shift. Simultaneously, the symmetrical layout of the double-row wheels keeps the trailer's center of gravity more centered during movement, reducing the risk of rollover even on complex road conditions such as curves and slopes.
