General information:

The supplied elements of the stage mechanics will include 3 lighting bridges based on winches

shaft and 8 decorative bars with electric drive based on shaft and manual winches

with crank winches.

The lighting bridge (shaft/tubular) is used to suspend lighting devices. As a drive source

shaft winches will be used, due to the minimization of the space necessary for the installation of this

the type of equipment and the method of transferring loads to the building structure. Accordingly,

It is unacceptable to use drum winches and winches with rope winding (so-called.

„bobinowych”).

The device has an electric drive using an electric motor (controlled by an inverter) and

Reducer.

Description of decorative bars

With electric drive:

Decorative bar (shaft/tubular) is used to suspend scenography, decorations and elements of trenching.

Shaft winches will be used as a source of drive, due to the minimization of the space necessary to install this type of equipment and the method of transferring loads to the building structure. In connection with the

The above it is unacceptable to use drum winches and winches with rope winding on

rope (so-called "bobinowych").

The device has an electric drive using an electric motor (controlled by an inverter) and

Reducer.

Description of the control system

The control system is powered from the building installation via a control cabinet. All Bars

and lighting bridges are controlled from one common control panel equipped with a screen

touch touchpad. It is equipped with a 10m long cable connected to the Harting socket

placed on the wall of the stage. The control panel has a STOP emergency stop. The control panel allows

to control one device or group of devices and choose the direction of movement. Each of the devices has

Inverter in the power supply and control system. Thanks to this, it is possible to implement the soft start function/

stops and smooth speed control available to the User from the control panel.

SAFETY:

- The control system shall meet the SIL3 requirements for the STOP safe function.

- Emergency stop occurs by pressing the emergency stop switch;

- a double system of limit switches (circuit breakers) will be provided in the equipment control system

Operating and emergency): the maximum and minimum levels that each device can reach will be determined by

limit switches located on the drive.

Part II - Exhibition system. 10 aluminum rails with a length of 1.5 m mounted to the walls. 40
