Truss and rigging
Eurotruss HD/FD34 Tower: base, head and sleeve identification
Identify the complete HD/FD34 tower assembly before selecting its load case: base, outriggers, hinge sets, sleeve block, head and hoist.
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.
HD/FD34 Tower is a ground-support system for raising supported truss assemblies. The vertical truss is only part of it. Match the base, hinge system, sleeve block and top section to the project documents; an FD34 beam chart does not rate this tower.
Section and connection references
- Top sections
- The manufacturer distinguishes a manual-hoist top and an electric-hoist top. Identify the exact supplied reference before choosing the hoist and load path.
- Sleeve blocks
- Different sleeve attachments serve different horizontal truss connections. The tower-truss family alone does not identify those attachments.
- Base and stabilization
- Base types, short or long outriggers and stabilizer bars are configuration choices; they are not interchangeable stability approvals.
The official webpage and leaflet state different maximum loads; the leaflet also qualifies its load figures as dead-hanging at maximum height. Do not choose a number from those publications for a lift. Obtain the applicable revision and approved load case for the complete assembly.
Parts and supporting documents
Prepare a complete bill of parts, including the specified hoist, chain route, pins and retainers, base supports and any required secondary retention. Electrical supply belongs to the selected electric hoist and its control system, not to the aluminum tower itself.
Prepare the configuration
- Record markings and references on the actual base, top, sleeve and hinge parts. Compare their combination with the supplier’s system drawing.
- Keep the assembly unloaded while a competent person checks visible damage, missing connection parts and sleeve obstructions. Do not energize the hoist or force the sleeve to test an unidentified assembly.
- Before erection, have a competent professional resolve ground bearing, stabilization, loads, lifting/working states, exclusion zones and operating limits for the site. Use the applicable assembly and operating manual.
Three technical questions
Can a manual top be replaced by an electric top without another review?
Do not assume so. Compare the head reference, hoist specification, chain path and the documented working configuration before making a substitution. A matching tower section is not evidence that the original base and load case remain valid. Keep the proposed change out of service until confirmed in the system documents.
The sleeve block will not travel freely. What can be checked first?
Keep the system unloaded and stationary. Compare sleeve and tower references and inspect visible alignment, obstructions and damage from a safe position. Do not pull harder with the hoist, alter guides or remove retainers to overcome resistance. Have the responsible specialist inspect the mismatch under the manufacturer’s procedure.
Do long outriggers make a roof safe outdoors?
No. The manufacturer distinguishes outdoor loading because coverings and roofs introduce significant bending effects. Document geometry, exposure, supports and all attached surfaces for the project’s stability assessment. Outrigger length alone does not define ballast, anchorage, wind limits or a weather action plan.
Limits before installation
Do not stand under the moving load or bypass holding and retention arrangements. Keep lifting capacity distinct from a final dead-hanging load case. A roof, a screen or a changed base requires its own documented assessment; this guide gives no erection sequence, universal ballast or operating wind speed.
