The front frame of the casing of the passenger information display panel

The front frame of the casing of the passenger information display panel

Made of hot-dip galvanized sheet, 2 mm thick and supplemented with PEM’s, using the technology of: laser cutting, edge bending, pressing PEM’s riveting and powder coating. Maintaining dimensional tolerances of each of the mounting points of separate panels, with external dimensions of the panel ranging from 1000 to 2000 mm, was ensured by using special equipment. The cover was powder-coated, which ensures a smooth texture and resistance to external weather conditions in order to meet the aesthetic requirements of the cover. The presented fragment shows the method of riveting corners using blind rivets. The proper strength of the connection of each of the four corners and the preservation of the angle of 90 degrees was obtained by using a special tool.

Maintaining dimensional tolerances of each of the mounting points of separate panels, with external dimensions of the panel ranging from 1000 to 2000 mm, was ensured by using special equipment. The casing was powder coated which ensures a smooth texture and resistance to external weather conditions in order to meet the aesthetic requirements of the casing.

Subassemblies for hanging the external LCD / LED display

Subassemblies for hanging the external LCD / LED display

Made of aluminium sheet 4 mm thick, using technology of: punching, edge bending and welding of reinforcements and brackets. Maintaining the dimensions and angle of bending at each point of each element over 2000 mm long and the strength of the connection of welded elements and pressed into the essential element was ensured. This is essential in the further assembly process with a given display screen. Resistance to various atmospheric conditions during operation is ensured by powder coating, with a powder paint appropriate for these conditions.

Subassemblies for hanging the external LCD / LED display

Subassemblies for hanging the external LCD / LED display

Made of hot-dip galvanized steel sheet, 3 mm thick, using the following technologies: punching and edge bending. It was ensured that the dimensions and bending angle were maintained in each point of each element over 1000 mm long. This is essential in the further assembly process with a given display screen. Resistance to various atmospheric conditions during operation is ensured by powder coating with a powder paint appropriate for these conditions.

Subassemblies of the supporting structure of the LED / LCD display

Subassemblies of the supporting structure of the LED / LCD display

Made of precision steel pipes of various diameters and mounting brackets, using the technology of: laser cutting, bending, milling, turning, gas welding with the use of specialized equipment. Technology ensures maintaining with very strict tolerance, even up to +/- 1 degree, the angle at which the pipe is connected to the bracket. The whole structure ensures breaking resistance as it is a supporting structure of heavy large-scale LED / LCD screens mounted in passenger transport vehicles.

LED/LCD display mounting subassemblies

LED/LCD display mounting subassemblies

Made of 6 mm thick steel sheet and special sleeves with two counter screws, using technology of: laser cutting, turning and gas welding. It is important to position the rings and obtain the appropriate strength of the welded elements.  These subassemblies constitute the mounting of heavy LCD or LED screens, mounted in passenger transport vehicles. They are powder coated with a dedicated paint  with a specific structure.

Rear cover of the casing of the passenger information display panel

Rear cover of the casing of the passenger information display panel

Made of hot-dip galvanized sheet, 2 mm thick and supplemented with PEM’s, using the technology of: laser cutting, edge bending, pressing PEM’s riveting and powder coating. Maintaining dimensional tolerances of each of the mounting points of separate panels, with external dimensions of the panel ranging from 1000 to 2000 mm, was ensured by using special equipment. The cover was powder-coated, which ensures a smooth texture and resistance to external weather conditions in order to meet the aesthetic requirements of the cover. The presented fragment shows the effect of PEM’s mounted in the back cover of the housing and masking external and internal threads. The versatility of the part was obtained by appropriate execution of cuts of the entry point of the power cable plug. Depending on the application, it is possible to easily remove the selected fragment of the hole masking before assembly.

Brackets that fix LED display elements

Brackets that fix LED display elements

Made of 5 mm thick aluminium sheet and pressed screws with metric thread of different diameters, using the following technology: laser cutting, bending, assembly of sleeves on eccentric presses and plasma welding of positioning brackets. They ensure a  very strong connection and are additionally protected against adverse weather conditions by powder coating with appropriate paint.
