Roll Stops

Roll stops on the tail gate – Components for securing rolling loads

Roll stops provide a critical safety function on the tail gate. They prevent rolling transport devices such as roll containers or carts from unintentionally leaving the platform and reduce additional load on surrounding mechanical structures. Within this category, the focus is on roll-off flaps, as they represent the primary component securing the platform edge. SULEJ Ladebordwand uses certified components that support stable load positioning and a controlled movement pattern throughout all lifting and lowering sequences. A roll-off protection system prevents uncontrolled rolling movements during the lift or lower process and significantly increases operational safety.

Defined blocking action of the roll-off flap – Safety at the platform edge

Roll-off flaps act as a mechanical barrier at the outer platform edge. During lifting and lowering, they prevent uncontrolled rolling of transport equipment and stabilize the load on the platform. Depending on the system, these flaps move manually or automatically into the locked position and reliably block the rolling path. On a lift gate, roll stops secure the transition between the platform and the ground and ensure stable load guidance. An intact roll-off flap is an essential component for defined and safe platform movement.

Construction types and materials – Variants of the flap mechanism

Roll-off flaps are available in various configurations. One-piece versions cover the full platform width, while two-piece systems allow segmented use of the platform edge. The flap is moved manually into the securing position, either by hand or by foot actuation at the platform edge.

For tail gate systems, roll stops are typically manufactured from aluminum alloys, combining low weight with sufficient structural strength. Steel is used locally for hinges, reinforcement plates or other safety-relevant connection components. Corrosion-resistant finishes such as powder coating increase durability against moisture and mechanical stress.

On a tail lift, varying forces act on the flap, hinges and mounting points throughout the lifting and lowering cycle. Hinges and locking elements must withstand repeated load changes to maintain reliable roll-off protection. The correct component is selected according to platform width, installation conditions and the structural requirements of the system.

Inspection intervals and wear indicators – Evaluating the flap mechanism on the lift gate

Roll stops belong to the safety-relevant components of a tail gate and require regular visual and functional inspections. Key indicators include the condition of the hinges, smooth movement of the flap and a reliably locking mechanism in the secured position. Deformation, corrosion, cracks or restricted hinge movement indicate progressive wear. Early replacement stabilizes load guidance and prevents consequential damage to adjacent platform elements.

Manufacturing precision and material quality – Technical requirements of roll-off protection

The functional safety of roll-off protection depends on dimensional accuracy, material quality and the design of the hinge and locking mechanism. Precisely manufactured components ensure effective blocking of the rolling path and controlled movement during raising and lowering. On a lift gate, dynamic forces act along the platform edge and require adequately dimensioned, corrosion-resistant construction.

The components offered are selected for load capacity, system compatibility and surface durability to ensure long-term roll-off flap performance. SULEJ Ladebordwand applies the technical specifications of each platform design when selecting suitable parts.

Frequently asked questions about roll stops and roll-off protection (FAQ)

Are roll stops mandatory?

For transporting rolling loads, functional roll-off flaps are mandatory in accordance with safety regulations.

How do I find the correct roll-off flap?

Important parameters include platform width, installation dimensions, flap mechanism design and the structure of the platform edge. The serial number of the tail gate enables correct assignment.

Can roll-off protection be retrofitted?

Retrofitting is often possible if suitable mounting points are available. Appropriate solutions exist for many standard systems.

How are roll-off flaps operated?

Depending on the design, the flap is positioned manually by hand or foot. The locking mechanism must engage audibly or noticeably to secure the rolling path.

When must a roll-off flap be replaced?

Deformation, damaged hinges, cracks or unreliable locking indicate immediate replacement is necessary.
