Load Diagrams

Load diagrams – capacity curve by load centre distance at the operating panel

Load diagrams represent the permissible load capacity of a tail lift graphically as a function of the load centre distance of the cargo. They combine lever length and maximum load into a single, clearly readable curve and serve as the central reference to prevent overload already during the loading process. At SULEJ Ladebordwand you will find load diagrams as replacement for faded or damaged originals – an important building block to keep the permissible limits visible at the operating panel.

Understanding the capacity curve by load centre distance

The lifting capacity of a tail lift decreases with growing load centre distance from the platform pivot – physically a consequence of the increasing lever arm. The load diagram depicts this relationship as a descending curve or as staggered kilogram values per load centre position. Operators can recognise at a glance which weight is still safely permissible at each platform position. This visual presentation is far easier to grasp than a pure table and supports decisions directly at the vehicle.

Mandatory marking under DGUV and UVV – visible at the operating panel

Load diagrams belong to the mandatory markings of a tail lift in commercial use and are anchored in regulations such as DGUV V52 and UVV BGV D6. They must be mounted visibly at the operating panel or in the immediate operating area so users can check the capacity limit before loading without searching. Weather- and UV-resistant execution ensures the curve remains clearly recognisable also after prolonged service. A damaged or illegible load diagram should be replaced promptly because its information is the basis for safe loading.

Benefits at a glance

• Visual curve by load centre distance – directly perceivable at the operating panel
• Mandatory marking in the sense of DGUV V52 and UVV BGV D6
• Weather- and UV-resistant design for long-term legibility
• Reduces the risk of unintended overload during loading

A clearly legible load diagram supports safe loading procedures and relieves the operator from uncertainty about the permissible weight.
