Aluminium truss bridge in 3D design – higher load capacity
The 3D aluminium truss bridge offers significantly higher stiffness and load capacity than the 2D variant thanks to its three-dimensional structure. Ideal for demanding handling tasks with large spans.
The Barbaric 3D truss bridge is the most capable vacuum crane variant — it extends the 2D bridge with a Z-axis, enabling multi-level movements between stacked storage levels or working heights. Typical applications are fully automatic multi-level flat-layout storage (CSF Multilevel), halls with multiple work plateaus or processes that must simultaneously serve the panel saw and a lower-positioned coating line infeed. The Z-axis offers several hundred millimetres up to several metres of stroke, depending on hall layout. The crane can be positioned more precisely than a 2D bridge but is mechanically more complex, accordingly higher in acquisition cost and requires more hall height. Asamer plans 3D truss bridges for industrial plants and multi-level panel storage in Czech Republic, Slovakia and Hungary — including structural dimensioning, software integration, ERP integration and commissioning.
A multi-level flat-layout storage per the CSF Multilevel principle requires the 3D truss bridge: panels must be moved from level 1 to level 2 or 3, sometimes within one motion. The Z-axis handles the vertical segment and hands over to the actual storage level.
If your process has multiple working heights — for example a high-positioned panel saw and a lower-positioned CNC worktable or coating infeed — the 3D bridge safely bridges the height difference. This saves additional handover equipment or conveyors.
Choose the 3D truss bridge only if you actually need multi-level movements — typical for CSF Multilevel or processes with significantly different working heights. For single-level area coverage, the 2D bridge costs around 30 % less and is sufficient in most applications. Before quoting, Asamer clarifies Z-axis requirements and hall geometry in detail.
Typically between 500 mm and 3 metres. Larger strokes are possible but require corresponding hall height and extend cycle time. Asamer dimensions the stroke based on your specific application.
In horizontal motion, speed is comparable. The additional Z motion extends overall cycle by a few seconds depending on stroke — rarely critical in operation, as Z motion only occurs on level changes.
Rarely — the additional investment over the 2D bridge pays off only with multi-level storage concepts or genuine multi-height processes. Small joineries operate more economically with a 2D bridge or an SSY system.
