Roller buffers are mounted at the rear of a trailer to reduce structural damage when reversing into a loading bay. They are especially valuable for trailers using adjustable-height suspension, where the buffer absorbs contact while allowing controlled movement.
How Roller Buffers Work
A roller buffer rotates upon contact, reducing friction and transferring impact energy away from the trailer’s rear frame or bumper assembly. This straightforward design supports daily fleet operations with minimal maintenance.
Typical Applications
- Reversing into fixed loading bays.
- Operations employing frequent height changes via air-suspension.
- General rear-end protection on box vans, curtainsiders and specialist trailers.
Advantages
- Reduces impact stress on the rear frame.
- Helps maintain alignment when docking repeatedly.
- Simple, robust construction and easy to service.
Considerations for Use
- Ensure the buffer is compatible with the trailer’s rear geometry and vehicle height-variation range.
- Inspect periodically for proper rotation, secure mounting and wear. Integrate this into standard fleet inspections.
- Use alongside docking systems such as guidance lighting, reversing aids and site traffic management to reduce reliance on the buffer alone.
FAQ
Are roller buffers suitable for all trailer types?
They are commonly used on box vans, curtainsiders and other trailers that regularly dock against fixed loading bays. Suitability depends on rear-frame design and operational demands.
Do roller buffers require regular maintenance?
Maintenance is generally minimal. Periodic checks for wear, correct rotation and secure fixing are recommended as part of standard fleet inspections.
Do roller buffers replace the need for standard bump stops?
Not necessarily. Some fleets use both systems, depending on docking frequency and the nature of impact. Roller buffers reduce sliding friction; bump stops provide static impact absorption.
