Eurotruss FD34: identify sections, CS1 parts and load charts
Identify FD34 straight sections and CS1 connection parts, then distinguish span-load charts from a complete tower or ground-support design.
Identify the truss
Ask GLMedia about rental options for your event. The proposal is subject to availability, confirmation of the model and configuration, and the venue’s technical requirements.
FD34 is Eurotruss square aluminum truss. This guide concerns straight sections; a tower, corner assembly or cantilever needs its own documented configuration. A matching outside size does not establish compatibility with another brand.
Section and connection references
- Section
- 290 × 290 mm; main tubes 50 × 2 mm; braces 20 × 2 mm.
- Connection family
- CS1-CON spigot, CS1-TP truss pin and CS1-RS2 R-Clip are separately identified parts.
- Selected straight-section codes
- FD34-050: 50 cm; FD34-075: 75 cm; FD34-100: 100 cm; FD34-200: 200 cm.
Use the load-chart case that matches the supports, span, orientation and load positions. UDL is distributed load in kg/m; CPL is a central point load in kg. The mm column records deflection. Values from different columns are not interchangeable and the chart’s standards notes must be resolved for the project.
Parts and supporting documents
Specify every straight section, connector, pin, retainer, corner, support and load attachment. The published CS1 family does not prove that unidentified loose hardware belongs to the system. Match markings and documentation; a connector that fits physically still needs identification.
Prepare the configuration
- Record manufacturer, family, section code, length and visible identification. Compare the proposed assembly with its approved drawing before connecting or loading it.
- With components unloaded and safely accessible, note bent tubes, damaged welds, distorted connector holes, corrosion or missing retainers. Isolate doubtful components for competent inspection; this observation is not an acceptance test.
- Have a competent rigger or structural professional confirm support reactions, load positions and the applicable chart. Obtain the assembly and inspection instructions for the actual parts before installation.
Three technical questions
A pin or spigot will not seat. Can I force it?
Stop before loading. Check family markings, section orientation and the exact connector, pin and retainer references against the component list. Look for visible distortion or debris without modifying parts. Do not drill, grind or substitute a similar pin. An unresolved mismatch stays out of service until identified by the responsible supplier.
Can I put a central load equal to the distributed-load figure?
No. First identify whether the plan is a distributed load or a point load and record the actual attachment positions. Compare the correct chart column, its units and the support case. Do not multiply a distributed value to authorize a point load, interpolate an unlisted case or treat a deflection value as capacity. Obtain an approved assessment for the actual loading.
Can I stand FD34 upright and use the beam chart as a tower rating?
No. A tower also depends on its base, stabilization, head, sleeve system and operating configuration. Identify the complete tower model and drawing; a straight-section label does not supply those conditions. Ground support, outdoor exposure and suspended loads need the applicable design and competent review before use.
Limits before installation
Do not change a loaded assembly or remove pins and retainers under load. Keep doubtful sections isolated and retain their identification. Repairs, damage acceptance and erection methods require the manufacturer’s applicable instructions; no generic repair or ballast quantity is established here.
