Overrun device with height adjustment of the AL-KO 270VB coupling for a 2700 kg trailer
The 270VB overrun device from AL-KO is a versatile solution designed for trailers and trailers braked with a 100 mm square drawbar, with a total weight from 1425 kg to 2700 kg. It is characterized by a maximum permissible vertical load of 120 kg, which ensures stability and safety while driving. The device is compatible with the AL-KO 1637/2051 braking mechanism and is equipped with a three-range return lever for easy operation and adjustment. The drawbar length is 1310 mm, and the total length of the device is 2418 mm.
The flat design of the underrun device allows the height of the coupling to be adjusted, allowing the trailer to be adjusted to the height of the towing vehicle. This feature is particularly important when a low connection height is required, allowing coupling well below the level of the cargo bed. The possibility of adjusting the towing height ensures optimum stability and safety during transport.
The overrun device is an advanced solution that significantly improves the safety and comfort of driving with a trailer or tow truck. Thanks to its use, it is possible to shorten the stopping distance and maintain a stable driving track when braking the set. The device automatically brakes the towed vehicle, cooperating with the car's braking system, which supports its operation and affects the smoothness of traffic. Using the overrun device not only increases road safety, but also contributes to reducing the wear of the braking system in the towing vehicle. Additionally, this device is also extremely functional when stationary, enabling effective blocking of the vehicle from rolling forwards or backwards.
Anti-corrosion protection
The black primed housing drive-on device uses a standard corrosion protection method. The priming process creates a basic protective coating on the surface of the element, providing a first barrier against corrosion. The housing is resistant to standard weather conditions, but may require periodic maintenance in the case of intensive use in difficult road conditions, especially when exposed to moisture and road salt. The black finish not only protects the device, but also gives it an aesthetic appearance. With proper maintenance and regular inspections, the device maintains its functional properties, ensuring reliability during trailer operation.
