AL-KO 251S overrun device with AKS3004 hitch for 2700 kg trailer with V-type drawbar

AL-KO 251S overrun device with AKS3004 hitch for 2700kg trailer

The 251 S underrun device from AL-KO is ideal for horse trailers, vans, caravans, flatbed trailers, truck trailers with a "V" drawbar, with a total weight of 1500 kg to 2700 kg. It is characterized by a maximum permissible vertical load of 120 kg, which ensures optimal load distribution between the trailer and the towing vehicle. The 251 S device is equipped with an AKS 3004 ball hitch with a stabilizer, which ensures a stable connection to the vehicle. Additionally, it has a three-range return lever, which makes it easier to operate and adjust.

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.

The device offers two mounting options: on the top or bottom of the drawbar, providing flexibility in adapting to different trailer designs. However, it should be noted that when mounted bottom, the maximum permissible drawbar height is 100 mm. This mounting versatility allows for optimisation of weight distribution, adaptation to different trailer designs and adaptation to specific application requirements, ensuring the safety and efficiency of the device in a variety of applications.

AKS 3004 ball hitch

The installed AKS 3004 ball hitch from AL-KO ensures a solid and safe connection to the towing vehicle. Thanks to the ergonomic lever with a soft grip, operating the trailer during connection and disconnection becomes more comfortable. The hitch has a Soft-Dock cover that protects the rear of the vehicle from scratches and the user from injuries during maneuvering. Equipped with advanced safety systems: a wear indicator informing about the need to replace components, a correct coupling indicator to ensure correct connection, and protection against incorrect coupling, minimizing the risk of accidental disconnection while driving. Additionally, the system prevents the trailer from tilting, protecting against uncontrolled movements.

Anti-corrosion protection

The ramp device with a hot-dip galvanized steel housing uses advanced anti-corrosion protection technology. The galvanizing process creates a durable coating on the entire surface of the element, effectively protecting against rust, corrosion and mechanical damage. The housing withstands extreme weather conditions, including moisture, road salt and temperature fluctuations, which is crucial for devices constantly exposed to difficult road conditions. Thanks to this protection, the device maintains its properties for a long time, minimizing the need for maintenance and replacement. This translates into long-term savings and reliability during trailer operation.
