As people's quality of life has increased, their entertainment has begun to diversify and a variety of commercial activities have emerged. This is why the use of trusses is increasing. The truss is a prop with a wide range of applications. As a metal product, it can be made of either iron or aluminium, and Dragon Stage is a specialist in the design of trusses, with aluminium trusses as its main product. With its excellent physical characteristics, aluminium trusses are favoured by many companies. The product we are going to introduce today is the lighting truss, which is also one of the common trusses and its main function is to connect the stage lighting equipment.

Mechanical requirements for lighting trusses
When designing a lighting truss, its stiffness and stability need to be taken into account. The principles of stiffness and stability calculations are also known as building mechanics. In other words, the strength and stability calculations are carried out to ensure that the structure can meet the requirements of safety and economy, that the structure does not deform excessively when subjected to weight and that it meets the requirements of use. In addition to this, sufficient consideration should be given to the economic aspects.
How lighting trusses work？
The main function of the light truss is to connect the column aluminium truss with the crossbeam aluminium light truss, which can drive the crossbeam up and down when the square sleeve is tugged with a hand chain hoist. In terms of bending resistance, the joist achieves greater bending strength for the same amount of material due to the concentration of the tensile and compressive sections at the upper and lower ends, which increases the internal force arms. The light truss is therefore highly resistant to compression.

·Determining the type of trusses
There are many types of lighting trusses and their appearance and size can vary according to the type. Therefore, when choosing a lighting truss, the use of the truss, the material, the support method and the construction conditions should be taken into consideration, so that the material and the amount of labour used is minimal.
·Build the base
Building the base is the most important step in the installation of the lighting truss. First place the four bases in approximate positions on the ground, fix the head to the bases with screws and then place the square sleeve on the upside down head. Then, attach the required crossbeams and connect the ends of the crossbeams to the two square sleeves on each side.
·Building the lighting system
After the first base has been erected, check that the base is level. Fix the diagonal brace extensions to the base, then tighten one end of the diagonal brace and column and tighten the other end with the base extensions to complete the light base. After erecting the stage lighting truss system, four safety diagonal braces should be installed on each column.
These are the considerations for the installation of lighting trusses, and we also need to consider safety in the installation process. When designing the lighting truss, it is important to ensure that the structure has sufficient strength and rigidity. As a professional manufacturer of lighting trusses, Dragon Stage has absolute control over the quality of the product.
