WINTERHOFF WW 220-RB ball hitch for a 2200kg trailer with a 50mm tubular drawbar

The WW 220-RB ball hitch from WINTERHOFF is a robust and reliable solution for heavy trailers and flatbed trailers with a total weight of up to 2,200 kg . Designed for mounting on a 50 mm tubular drawbar and on an overrun device with a 50-51 mm diameter slider tube , it guarantees a stable and secure connection to the towing vehicle. It boasts a permissible vertical load of 100 kg , enabling the transport of heavy loads while maintaining optimal weight distribution.

The tow ball is ECE approved , type approval number: E1 55R-01 0399. This means the product has been tested and approved for use in accordance with European requirements for vehicle and trailer coupling components. When properly installed for its intended purpose, no additional TÜV registration is required. Thanks to its robust design and high-quality workmanship, the tow ball is the ideal choice for professionals and users requiring reliable equipment for transporting heavy trailers, ensuring safety even in the most demanding operating conditions.

A ball hitch is a component mounted on the trailer's drawbar, used to securely connect the trailer to the towing vehicle . Its design allows for stable seating on the tow ball, ensuring a secure connection and smooth trailer movement while driving. Using a ball hitch is important because it minimizes the risk of the trailer becoming detached during transport and ensures proper trailer control, especially during turns and maneuvering. Using a ball hitch increases the safety and comfort of transporting various loads.

Consumption monitoring

The ball hitch wear indicator is a solution that significantly improves the safety and reliability of the trailer-to-vehicle connection. This precise monitoring system allows the user to quickly and easily assess the technical condition of the hitch without the need for specialized measurements. The indicator clearly displays the level of wear of the hitch ball, signaling the need for replacement before dangerous situations arise. This effectively prevents problems related to excessive wear, such as increased play or the risk of unexpected trailer disconnection while driving.

Anti-corrosion protection

Made of high-quality steel , these ball couplings undergo a precise galvanizing process, which is key to their durability and reliability. Galvanizing involves coating the coupling's surface with a layer of zinc, creating an effective barrier against atmospheric factors such as moisture, road salt, and temperature fluctuations. The resulting coating provides excellent protection against rust and corrosion and significantly increases the coupling's resistance to mechanical damage .
