Truss and rigging
Totems and projection towers: identify the whole assembly
Review the base, upright, top attachment and load position together.
Define the tower and its purpose
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.
A fixed totem can position a projector above floor-level obstructions. It does not become a lifting tower or an access platform; choose a system documented for the intended task.
A vertical truss section does not identify an approved tower. Record each component and the intended indoor or outdoor use. A lifting tower and a fixed projection totem have different functions.
Structural scope and equipment interface
- Structural scope
- TOMCAT requires strength and stability review of assembled structures. Its general beam tables do not validate a freestanding tower.
- Equipment interface
- Identify the projector, lens, mounting frame and supported orientation in their own documentation.
Base dimensions or truss capacity alone do not establish tower stability. Have the complete arrangement assessed by a competent structural professional.
Document the complete assembly
Specify the base, uprights, connectors, approved top attachment and any designed stabilizers, anchors or ballast. Include equipment, lens, frame, cable weight and load position in the design information.
Checks before positioning equipment
- Check the base reference, upright and connector references, top attachment and equipment position against the drawing. Resolve missing references or substitutions before assembly.
- Resolve bearing surface, access exclusion, cable routing and electrical bonding where required.
- Inspect attachment, locks and clearances before use; verify projection alignment without altering structural parts.
Three technical questions
Does a larger base plate automatically approve extra height?
No. Review height, eccentricity, lateral actions and the actual support system. Use the approved stability design.
Compare actual base footprint, tower height, equipment position and attached accessories with the approved drawing. If any differs, stop the setup and ask the designer to review that change; adding weight by eye is not verification.
Can a shelf replace the projector mounting frame?
Only if that equipment and support arrangement are documented and approved. Check attachment, ventilation, orientation and retention; weight alone is insufficient.
Find the mounting points and approved orientation in the projector documentation. Match the frame or shelf reference and fasteners to that arrangement, and check that neither ventilation nor required service clearance is blocked. If the interface is undocumented, do not install the projector.
The image moves. Can I tighten or brace the tower during use?
Keep the area clear and refer movement to the responsible team. Separate optical adjustment from structural movement; do not add unapproved ties or ballast.
From a safe location, report whether the base/upright moves or only the projected image changes. Record when movement occurs and any contact or pull from cables. The responsible team must investigate before reuse; do not shake the tower to test it.
Limits before installation
Fabric wraps, signs, wind and moving equipment can change the design case. Reassess changes before use. Never use a person holding the tower as stabilization.
Manufacturer documentation
The TOMCAT manual contains general instructions; the Eurotruss document shows an example tower system. Confirm the documents for the selected assembly and projector; these references do not approve their combination.
Choosing a projection tower location and scope
For a conference or awards event, start with the date, room, approximate screen and audience positions, and the height you want to investigate. The tower reference is not needed yet: we can assess supply and an installation or assistance scope using the available information.
Compare a floor tower location with a lower position or suspension from documented venue points. The video team must confirm that each option meets the image requirement; the structural reviewer must assess its support. Moving the projector does not automatically retain the previous design.
- Sketch the complete footprint for the base, stabilizers and protected area, alongside circulation, tables, cameras and award-recipient routes. Do not reserve only the upright footprint.
- Separate confirmed dimensions and weights from pending information: projector, lens, frame, accessories and cables. Describe the floor, slopes and environment so the actual assembly can be assessed.
- Agree on installation and maintenance access, work windows and who reviews audience conflicts. If the required footprint does not fit, investigate another location or documented support before reducing bases or removing parts.
Can we request a proposal before choosing the projector?
Yes. Share the goal and tentative location. We can compare scopes and identify the information the video team needs to provide. The tower, interface and configuration are confirmed once equipment and conditions are defined; a preliminary quote does not approve the installation.
Can scenery hide the base?
Include the covering, dimensions and attachments in the inquiry. Its effects on loads, access, ventilation and the protected area need review; a finish does not authorize concealing damage or removing parts. We can assess another position or visual treatment that retains design conditions.
