HOAC® Truss System

Your vision — our mission

Stable lightweight construction

HOAC® trusses
For every occasion

It is impossible to imagine stage construction without trusses, both in rigging and in decoration construction. In addition to our standard sizes and lengths, we manufacture trusses individually according to your requirements – starting from one piece. We can manufacture trusses in 4.47 m or 176 inch lengths, straight or curved and with individual cross bracing for e.g. speaker cut-outs. We make it happen!

HOAC® Trusses
Simple assembly

With the supplied bolts, nuts and washers, you can screw HOAC® trusses together quickly and without special tools. This type of connection gives you an even, straight surface with no protruding parts, as is common with cone and bolt connections. Ideal for stage sets, because the trusses disappear under the cladding.

HOAC® Trusses
IIdeal for stage sets

The screw connection of the HOAC® truss allows for all-round cladding, because unlike the cone connection, no bolts stick out. Perfect for breathtaking stage sets. We manufacture custom-fit trusses for you according to your requirements. The highlight – your in-house workshop can easily screw on stage decorations or similar to the screw head of the truss. More flexibility is not possible.

07 Rigging

Rigging With
HOAC® Trusses

The truss – often barely visible and yet indispensable. Especially for black box theatres without upper machinery, these are used for loads such as spotlights, decorations or ceiling sails. Whether for concert halls, trade fairs or stage sets, we plan your stage technology together with you.

Easy Maintenance
with maintenance bridges

In addition to regular maintenance, it is important to act quickly in case of malfunctions. With our electric maintenance bridge, you can drive the technician safely and conveniently to the site at any time, even when the stage set is still standing. Once the technician has finished, you can park the bridge almost invisibly in the corner until your next assignment.
