Trailer tipping is a known operational risk, particularly when loading high density products. The issue is more pronounced on shorter urban trailers, where weight applied to the front bulkhead can create a strong forward tipping moment.
When a trailer is positioned in a bay or yard without a tractor unit attached, the neck is unsupported. As loads are placed against the bulkhead, the weight transfer can cause the trailer to pitch forward with little warning.
A widely used mitigation method, including in parts of mainland Europe, is to position a trestle beneath the bed plate. This provides a fixed support point and prevents the trailer from rotating regardless of the loading sequence.
Don-Bur has developed a number of engineered alternatives, including heavy duty support legs that offer robust, repeatable protection against tipping during loading.
Lighter options are also available that mount directly to the front bulkhead, providing a simpler installation where full-duty legs are not required.
FAQs
Why do trailers tip forward during loading?
Forward tipping typically occurs when heavy, dense loads are placed against the bulkhead while the trailer is not connected to a tractor. The weight applied at height generates a tipping moment that can rotate the trailer over its landing legs.
Do short urban trailers experience tipping more often?
Yes. Shorter trailers have reduced overall length and a shorter distance between the load position and the landing legs. This increases the rotational force applied to the neck during loading.
How do anti-tip support legs improve safety?
Anti-tip legs provide a rigid structural support under the trailer neck, preventing forward rotation even under high loading forces.
Are lighter anti-tip options available?
Yes. For operations with lower loads or less frequent bulkhead-side loading, front bulkhead-mounted support systems can provide an effective, lightweight alternative.
