The History of Creation of Cartable Lighting Tower
Who invented the 1st portable lighting tower?
This depends principally on your definition of a lighting tower. An extensive definition might include something as easy as a candle or primitive torch placed on a tall mast to cast light over an enormous area, such a device has doubtless been in use since the Stone Age.
In more current history it’s un-clear as to when the modern lighting tower was invented. Researching patent applications suggests that machines not dissimilar to today’s lighting towers were being designed in the 1930s.
A patent from 1932 shows what could be the 1st machine of its kind filed in US patent 1934576 and is named as a Portable floodlighting unit for airports.
The patent describes a framework with 4 wheels at every corner ( permitting the machine to be towed ), a generator powered by an engine and one massive electrical lamp at each end of the vehicle. The machine is meant to be used to provide on-demand lighting of alternative landing sites at airfields on occasions when the main landing areas are out of use because of adverse weather conditions.
More lately in 1980 a US patent 4181929 was filed for a Portable illuminating tower that illustrates a much more close similarity to modern day lighting towers.
The US patent 4181929 describes a conveyable lighting tower consisting of a base frame ( which contains an engine and generator ) and a vertical, extending, hydraulic mast with two electric lamps at the upper end. The unit doesn’t permit towing but instead is light and compact enough to be simply transported. The design also includes jack legs that are now common place on all lighting towers to guarantee stability in gusty winds.
This is reasonably a big development in the history of the lighting tower as this patent mostly forms the basis of most present day lighting towers which contain similar elements such as a base that stores the engine and generator with an extending hydraulic mast that supports the luminaries.
The following patent was filed later on in the same year of 1980 but was for a solution to provide more intensive illumination. The US patent 4220981 describes a chassis with four wheels to hold the generator and engine and 2 folding telescopic masts at opposite corners of the frame that each hold a cluster of electric lamps. The design also allows for the masts to be revolved enabling finer control over the area of illumination. By offering 2 masts the light tower also allows for illumination over nearly all sides of the machine. This is not like previous light towers which generally offer illumination on only 1 side of the machine.
Since 1980 considerable progress has been made by lighting tower manufacturers. Though the final design has varied tiny from those seen in the 1980s many enhancements have been made to make lighting towers better to use and more environmentally friendly.
The Hylite lighting tower from Taylor Construction Plant includes Adjustabeam technology which permits the user to adjust the direction of each lamp from the ground. The TCP Hylite also has a flexible chassis design which allows virtually any generator to be used to power the light heads.
The TCP Ecolite lighting tower in addition has damaged new ground by exploiting intensely economical lamps to reduce fuel consumption seriously, which is very timely seeing as global warming is beginning to become a more and more prevalent concern.
