HEIGHT ADJUSTABLE
OVERRUN DEVICE COMPACT
510 to 1,000 kg
YOUR ADVANTAGE
Time is money
Commercial operators in particular appreciate trailer concepts that permit all kinds of towing vehicles (cars, trucks) to be changed
flexibly and quickly. The height-adjustable overrun devices represent
a successful product line from AL-KO which has conquered the european market.
- Fully mounted unit (without hitch components)
- Hot-dip galvanised
- Delivery time 20 working days (see following product page)
- Accessories can be retrofitted
- Changeover relay lever for certain types (see following product page)
TECHNOLOGY
- The hitch components must be replaced by a specialist workshop.
- The maximum free drawbar lengths are shown in the following table. All clamping mounts can be clamped. If the clamping mounts are welded, the max. free drawbar length will be reduced.
SURFACE TREATMENT
- Hot-dip galvanised
- Coupling heads, eyes and various small parts galvanised

- Operating instructions
1. Additional toothed lock washers in the highly loaded joints - doubling the teeth - a significant advantage compared to conventional tooth heads. This positivelocking connection gives our overrun devices their stability and long service life.
2. Large ground clearance with low suspension due to the cranked drawbar section and the low structural height of the overrun device.
3. The forces are transmitted directly via cable and brake rod. This means we achieve low-friction force transmission compared to conventional Bowden cable transmission. Consequently, brake force is increased and the braking distance shortened.
A light special box section even permits free drawbar lengths up to 2,300 mm.
The special box section provides maximum stability with the lowest possible inherent weight.

IMPORTANT!
- Combine AL-KO overrun devices with AL-KO wheel brakes
AL-KO overrun devices comply with the latest ECE Directives. They may only be combined with the corresponding AL-KO wheel brakes. Please note that the brake system will not function with other combinations.
- Excessive nose loads
lead to an increase in plain bearing friction forces. This results in a decrease in braking effect. Consequently, please comply with the prescribed nose loads.
- Type plates
must not be rendered illegible by painting or covered by attachments.
- Reinforced overrun devices
Overrun devices, drawbars and hitch components of a reinforced version must be installed on trucks, buses or towing vehicles with hard suspension. Please contact us.
