Product Description

EVT290S-Spindel | Adjustable Leveling Spindle

The EVT290S-Spindel is an essential structural accessory designed for EVT290S 290 mm square conical aluminum truss systems. This adjustable leveling spindle (screw jack) is the perfect solution for erecting truss structures on uneven surfaces, such as outdoor festival grounds, sloped sidewalks, or older indoor venues with irregular flooring. By attaching to the bottom of a truss leg, it allows for precise height adjustments to ensure the entire grid or tower remains perfectly level and plumb.

Manufactured from high-grade 6082-T6 aluminum alloy and fabricated in accordance with TUV specifications, the EVT290S-Spindel delivers heavy-duty load-bearing performance. It integrates seamlessly with the truss using a secure conical connection system, including one set of conical couplers, pins, and safety clips.

Primary Applications:

• Outdoor Events: Compensates for dips and bumps in grass or dirt to keep stage roofs stable.
• Sloped Venues: Essential for maintaining vertical tower alignment on ramped or raked surfaces.
• Precision Leveling: Fine-tunes the height of truss legs to ensure accurate alignment of LED walls and overhead grids.

Key Features

• Precision Height Adjustment: Threaded spindle allows for exact leveling on irregular ground.
• Stability Solution: Prevents structural lean and ensures safe weight distribution on uneven terrain.
• Compatibility: Fits F34, EVT290S, and other brands utilizing the 290 mm square truss system. Exact fit with other manufacturers is not guaranteed.
• Professional Brushed Finish: High-quality aluminum finish matches standard truss lengths.
• Secure Conical Connection System: Includes conical receiver, coupler, Pins, and R-clips.
• Durable Construction: Heavy-duty threading and 6082-T6 alloy construction for reliable load support.

Designed by Evolve Truss, the EVT290S-Spindel is compatible with 50 mm (1.97″) clamps, allowing seamless integration with common truss accessories and rigging hardware.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information: The spindle is a load-bearing component. Ensure the thread engagement is within the manufacturer’s specified safe range. Do not over-extend the spindle, as this significantly reduces its load capacity and stability.

Important Guidelines for Safe Use:

• Never exceed the rated load capacity of the truss system or the spindle itself.
• Ensure the base of the spindle rests on a solid, stable footing (use base plates or cribbing on soft ground).
• Check the thread for damage or debris before use.
• Handle truss components with care—avoid dropping, dragging, or improper stacking.
• Assembly and installation must be performed only by trained and qualified personnel.
• Ensure all Couplers, Pins, and R-clips are correctly installed and fully secured.
• Account for all applicable forces, including dynamic and transverse forces such as wind loads.
• Do not mix truss components from different manufacturers.
• All truss structures must be reviewed and approved by a licensed professional engineer.

⚠️ Compatibility Warning for Mixed-Brand Builds

Crucial Steps for Safe Assembly:

• Verify all dimensions before integrating with other truss brands.
• Confirm conical connector type, node spacing, and system geometry.
• Mixing components without verification may compromise structural integrity and safety.
