This article describes the installation process of an indoor pop concert stage at a venue in Zhengzhou City, Henan Province.
The stage’s overall design features an aluminum lighting truss system. It incorporates three - sided Layher LED trussing and a mechanical staging system.
On the roof of the lighting truss, there are multiple groups of hoisting machines for lighting fixtures and LED screens. The main stage consists of several groups of motor - powered rising stages. The stage is surrounded by large LED displays on three sides, along with lighting and sound systems.

Note that
The wheel on the iron chain below should be large.
The auxiliary tower crane base should be connected to the column base, not just the handrail part
The vertical part of the auxiliary tower crane has a flexible connection base at the end, which facilitates vertical and storage
The 18 column (the part that needs to be erected simply) must be erected with an iron auxiliary tower crane. if it is to use aluminum alloy, it shall bent all at once.

The installed auxiliary tower crane, with wheels, is very easy to move and perfectly fits with the column sleeve, increasing speed.

There are two key points to erecting a large truss.
Firstly, before pulling it up, the gourd chain should be straightened first.
Secondly, starting from the lifting, the hoist cannot stop until it stands upright, and the electric hoist should run for an additional two seconds.

If there is mechanical handling, after the cross arm is installed on the ground, it can be directly moved to the designated location.

8 workers set up the scaffolding at a speed of 6 grids on the ground, 16 meters high, and takes approximately 60 minutes
There are two groups of layher scaffolding workers on site, each consisting of eight people.

The lifted truss is first assembled outside the site, and the lighting is installed. Then, after the main truss is lifted, it is pulled up with a hoist.
when two eletrical hoists are used for lifting the trussing system, usually it should be arranged inside and outside

how to secure the prominent truss outside
Measures have been taken to prevent chain slippage.
To prevent the sound crossbeam from being pulled down, there is an safety strap at the back that is tightened with a small chain hoist.
Assemble the LED display screen and lock the pillars with wire every meter.
The horizontal bar is not locked.
The iron base should have holes left for future construction of the layher frame truss
Three wire trunking is the most commonly used
For the best sound effect, the linear array is curved and fixed with safety straps
Fixation and method of pull-down
At the forefront of the stage, the light frame should be concealed inside the gourd truss to maintain its aesthetic appeal
