WINTERHOFF WW 30-D2 ball hitch for a 3000kg trailer with a 45-46mm pipe drawbar, cast iron
WINTERHOFF WW 30-D2 ball hitch for 3000kg trailer with 45-46mm pipe drawbar, cast iron
The WW 30-D2 ball coupling from WINTERHOFF is a robust and reliable solution for heavy trailers and flatbed trailers with a total weight of up to 3,000 kg . Made of durable cast iron, it ensures maximum durability and load resistance. Designed for mounting on a 45-46 mm drawbar and on an overrun device with a 45-46 mm diameter slider tube , it guarantees a stable and secure connection to the towing vehicle. It boasts a permissible vertical load of 150 kg , enabling the transport of heavy loads while maintaining optimal weight distribution.
The tow ball is ECE approved , type approval number: E1 55R-01 0640. This means that 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
The ball couplings, made of high-quality cast iron , undergo a precise galvanizing process, which is key to their durability and reliability. This advanced corrosion protection method involves electrolytically depositing a thin, uniform layer of zinc on the cast iron surface of the coupling. The resulting coating creates an effective barrier against aggressive atmospheric factors such as moisture, road salt, and temperature fluctuations. Galvanizing not only provides excellent protection against rust and corrosion but also significantly increases the coupling's resistance to mechanical damage. This process is particularly important for cast iron, which, while durable, is susceptible to corrosion.
