The lighting bar is an element to which lighting  equipment is attached in one line with possibility to move it vertically. In standard, minimum three lighting bars are installed above the stage – a proscenium, a mid-stage and a horizontal lighting bar.

Such truss is suspended to a stage winch with attested slings.
To hang lighting bars we use line winches of a minimum lifting capacity of 500 kg.
The truss is equipped with an aluminium beam in where the DMX socket and other socket outlets are placed. The number of sockets may vary depending on an individual design.

The lighting bars are supplied with power via:
a) cable reels
b) ribbon cables
c) pantograph.
