The History of Creation of Cartable Lighting Tower
Who invented the first cartable lighting tower?
This depends mostly on your definition of a lighting tower. An extensive definition may include something as straightforward as a candle or primitive torch placed on a tall mast to cast light over a big area, such a device has probably been in use since the Stone Age.
In more up to date history it’s un-clear as to when the modern lighting tower was invented. Researching patent applications indicates that machines not dissimilar to today’s lighting towers were being designed in the 1930s.
A patent from 1932 shows what might be the 1st machine of its kind filed in US patent 1934576 and is named as a Portable floodlighting unit for airfields.
The patent describes a frame with 4 wheels at each corner ( allowing the machine to be towed ), a generator powered by an engine and one giant electrical lamp at each end of the car. The machine is meant to be used to provide on-demand lighting of alternative landing sites at airports on occasions when the main landing areas are out of use because of harsh weather conditions.
More recently in 1980 a US patent 4181929 was filed for a Portable illuminating tower that illustrates a much closer similarity to present day lighting towers.
The US patent 4181929 describes a cartable lighting tower composed of a base frame ( which has an engine and generator ) and a vertical, extending, hydraulic mast with 2 electric lamps at the upper end. The unit doesn’t permit towing but instead is light and compact enough to be easily transported. The design also includes jack legs that are now common place on all lighting towers to ensure stability in gusty winds.
This is quite a serious development in the history of the lighting tower as this patent principally forms the root of most present day lighting towers which contain similar elements like a base that stores the engine and generator along with an extending hydraulic mast that supports the luminaries.
The next patent was filed later on in the same year of 1980 but was for a solution to provide more extensive illumination. The US patent 4220981 describes a chassis with 4 wheels to hold the generator and engine and 2 folding telescopic masts at opposite corners of the frame that each hold a cluster of electrical lamps. The design also allows for the masts to be rotated 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 prior light towers which generally offer illumination on only one side of the machine.
Since 1980 considerable progress has been made by lighting tower manufacturers. Though the overall design has varied tiny from those seen in the 1980s many improvements have been made to make lighting towers easier 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 permits just about any generator to be used to power the light heads.
The TCP Ecolite lighting tower has additionally damaged new ground by exploiting intensely cost-effective lamps to reduce fuel consumption seriously, which is particularly timely seeing as global warming is beginning to become a more and more plentiful concern.
