Lifting Mechanism & Lifting Arms

Lifting arms: The load-bearing joint of the tail gate

Anyone who regularly works with a tail gate knows the force with which heavy loads can be moved precisely to loading height. Behind this performance are components that operate in the background while playing an essential role in stability and safety. Among these key elements are the lifting arms. As the load-bearing connection between the vehicle frame and the platform, they ensure reliable power transmission and controlled pivoting movements. In this category, you will find lifting arms and matching spare parts tailored to the requirements of modern lift gates, providing stable and safe functionality. At SULEJ Ladebordwand, we rely on components that have proven themselves in daily use — thanks to precise manufacturing, robust materials and dependable fitting accuracy.

Detailed function: Power transmission and stabilization

The primary task of lifting arms is to transmit the force generated by the hydraulic cylinders precisely and with minimal loss into the platform of the lift gate or tail lift. At the same time, they stabilize the entire movement and prevent lateral forces, misalignment or jamming — even when loads are unevenly distributed. In daily operation, lifting arms are exposed to significant lateral, compressive and bending forces. This makes a precisely executed and robust construction essential to ensure safe, controlled and reliably stable positioning of the entire lifting mechanism.

Designs and materials of lifting arms for tail gates and lift gates

Lifting arms differ depending on the model and design of the tail gate. Common types include welded steel structures or high-strength cast components engineered for the dynamic loads encountered in daily operation. Lift gates use these components in tailored formats, matched to lifting capacity, dimensions and the structural parameters of each system. A precisely manufactured construction ensures reliable power transmission and smooth pivoting movement — even under varying load conditions.

Maintenance: Ensuring dependable operation

To ensure long-term reliable operation of a tail gate, lifting arms and their bearing points should be inspected regularly. This includes visual checks for wear, corrosion or cracks in the material, as well as inspection of pivot joints and bolts that are exposed to particularly high stress. Proper lubrication minimizes friction and ensures smooth motion throughout the entire lifting mechanism. The operational profile of a lift gate significantly influences maintenance intervals. With consistent servicing, functional issues can be prevented and long-term operational safety of the lifting system can be ensured.

When quality ensures safety: Lifting arms in professional use

Lifting arms are among the safety-critical components of a tail lift. Their quality directly affects the stability and functionality of the entire mechanism. Poorly manufactured or low-quality aftermarket parts may show material weaknesses or dimensional inaccuracies — increasing the risk of malfunction or even system failure. At SULEJ Ladebordwand, only components with verified material quality and precise dimensional accuracy are used. These standards ensure consistently reliable operation of the lift gate and secure functional and operational safety in professional environments.

Benefits of high-quality lifting arms

• Stable power transmission for safe and controlled lifting
• Precise movement guidance of the entire lifting mechanism
• Reduced wear thanks to robust and accurately fitting construction
• Long service life even under heavy use
• Reliable functionality in continuous professional operation

The lifting arms offered in this category are compatible with common tail gates and lift gates. They meet the requirements of commercial vehicle applications and allow precise replacement according to manufacturer specifications — ensuring durable, precise and safe performance in daily operation.

Frequently asked questions about lifting arms for tail gates (FAQ)

How can I identify a defective lifting arm?

Typical signs include platform play, unusual noises such as creaking or squeaking, and visible material cracks. If the tail gate no longer moves cleanly into its end positions, this may also indicate issues with the lifting arms or their bearings.

Can lifting arms be repaired?

Repairs or welding work are not recommended, as these components are exposed to high loads and their structural integrity cannot be reliably restored. In case of damage, replacement with a suitable quality spare part is the safest solution.

How often should the bearings of lifting arms be lubricated?

Lubrication intervals depend on usage frequency and environmental conditions. The tail lift maintenance manual provides binding specifications for each system.

Can I replace lifting arms myself?

Replacement is safety-critical and requires technical expertise as well as the proper tools. A qualified workshop should perform this work to ensure correct alignment and safe functionality.

How do I find the correct lifting arm for my tail gate?

Identification is based on the model designation of the tail gate. Important details such as lifting capacity, platform size or manufacturer information help determine the correct spare part. With these specifications, a lifting arm can be selected that fits the existing system precisely and ensures safe operation.
