Truss and rigging
Identify truss before selecting tables or assembling it
Match the physical module, connection system and inspection record to its documentation.
Establish module identity
Ask GLMedia about options for your event, subject to availability and evaluation of the configuration.
Record manufacturer, series, module length, production identification and connector type. A similar section or an apparently matching pin does not establish structural compatibility. Keep unidentified material out of the proposed assembly pending confirmation.
Product documents and inspection records
- Documentation example
- Prolyte separates general instructions from product-specific data. Use the documentation for the identified family.
- Inspection records
- Keep a traceable record for each module. A dated inspection report is different from a generic product certificate.
Acceptance criteria depend on the actual product and applicable inspection procedure. Do not assign capacity or remaining life from appearance, age or a generic table.
Compare options for the event
A truss inquiry can begin with its function: lighting support, screen integration or a scenic structure. Describe approximate size, intended equipment and whether support comes from the floor or venue points. If pieces are already available, photos of labels and connectors can guide identification; they do not replace inspection or compatibility approval.
Inspection inputs and segregation
Prepare the correct manuals and load tables, module identification, connection hardware list, inspection history and a way to segregate questionable material. A qualified inspector needs access and the appropriate measuring methods.
For the cited Prolyte system, the manual requires signed and dated records of initial and periodic inspections. Link each finding and disposition to the individual module identifier. A product certificate alone does not record the current condition of that physical piece.
Record findings before disposition
- Compare identification and geometry with the manufacturer’s documents before selecting the load case.
- Check for visible deformation, cracks, corrosion, weld irregularities, connector damage and missing or incorrect hardware; stop if condition or identity is uncertain.
- Record the module, location of any finding, photographs, date and responsible reviewer. Follow the applicable inspection and disposition procedure.
Three technical questions
The labels are missing. Can section size identify the series?
No. Preserve available markings and records and refer identification to the manufacturer or representative. Do not copy a label from a similar module.
The dent looks small. Can capacity simply be reduced?
Do not invent a reduction. Remove the module from use and obtain assessment against the applicable manufacturer’s criteria.
Can a bent connector be straightened or a crack welded on site?
Do not improvise a repair. Consult the manufacturer and follow its approved repair or retirement process before any return to service.
Limits before installation
Do not force incompatible connections, conceal findings with paint or return isolated pieces to usable stock without documented disposition. Inspection does not approve a different structural design.
Manufacturer identification and inspection references
The cited Prolyte manual contains general instructions; read it together with the product-specific data for the identified family. Do not transfer inspection, repair or load criteria between manufacturers or series.
Comparing rental and purchase of truss and hoists
Begin with the solution you need to repeat: function, geometry, dates, venues and expected variations. We can assess rental, purchase or supplementing an identified owned system with supply and assistance as agreed. Compare proposals for the same configuration and scope rather than treating a price per section as the total cost. Availability is confirmed separately.
- For rental, request the included sections, hardware, hoists, controls and accessories; separate transportation, installation, removal, operation, inspections and project review. State the rental period and potential event changes.
- For purchase, include packing and transportation, storage, inspection, maintenance, documented spare parts and required personnel. Identify who will keep manuals, records and traceability during use. Do not calculate payback without actual costs and utilization.
- For used equipment, request provenance, component identity, history and applicable inspection before deciding. A photo or generic certificate does not establish condition or compatibility. Include adaptation costs for each project: owning components does not approve future installations.
Should we buy if we repeat the same conference?
We can compare the repeated configuration and venue changes alongside transportation, storage, staffing and maintenance. Keeping some owned equipment and renting the remainder as a documented assembly is another option to assess. The decision needs actual proposals and costs rather than a universal event count.
What should I send to compare two quotes?
Send the date, venue, goal and approximate sketch, each offer’s inclusions and available owned equipment. Mark differences in system, documentation, personnel, logistics and schedule; we can organize missing items and options before quantities are finalized. References and documents establish compatibility, not a need to match the price.
