MODERNIZATION OF LIGHTING INSTALLATION OF THE PORTAL CRANE.
We offer the existing lighting installation equipped (Regular system of lighting):
On a crane portal: 4 Searchlights of floodlight PZS-35 with PZh-220- 500 with a power of 500 W
Under the crane operator's cabin: 2 Deep emitters with arc mercury lamps of a high pressure of DRV-500 with a power of 500W
To replace on light-emitting diode, namely on LED searchlight, the following type:
On a crane portal: 4 pieces. LED searchlights of a floodlight of LED SP 300W 90°
Under the crane operator's cabin: 2 pieces. LED searchlights of LED SP 150W 10°, with a protective corner of the lamp 30 ° (The corner characterizing a zone within which an eye of the observer is protected from direct action of a lamp (in our case of light-emitting diodes)
The light sources offered for modernization are energy efficient – the total connected power will make 1500 W, instead of present 3000 W, thus luminous efficiency is higher, than at the regular. The guaranteed service life not less than 50 000 hours.
