The History of Creation of Conveyable Lighting Tower
Who invented the 1st cartable lighting tower?
This depends mostly on your definition of a lighting tower. A detailed definition may include something as easy as a candle or primitive torch placed on a tall mast to cast light over a large area, such a device has likely 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 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 first machine of its kind filed in US patent 1934576 and is named as a movable floodlighting unit for airfields.
The patent describes a frame with 4 wheels at each corner ( permitting the machine to be towed ), a generator powered by an engine and one large electrical lamp at every end of the auto. 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 closer similarity to present day lighting towers.
The US patent 4181929 describes a cartable lighting tower composed from a base frame ( which contains 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 lightweight and compact enough to be simply transported. The design also includes jack legs that are now common place on all lighting towers to ensure stability in strong winds.
This is quite a big development in the history of the lighting tower as this patent principally forms the basis of most present day lighting towers which contain similar elements like a base that stores the engine and generator 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 in depth illumination. The US patent 4220981 describes a framework with four wheels to hold the generator and engine and 2 folding telescopic masts at opposite corners of the chassis that each hold a cluster of electric lamps. The design also allows for the masts to be rotated enabling finer control over the area of illumination. By offering two masts the light tower also allows for illumination over nearly all sides of the machine. This is unlike previous light towers which often offer illumination on only one side of the machine.
Since 1980 substantial progress has been made by lighting tower makers. Although the overall design has sundry small from those seen in the 1980s many enhancements have been made to make lighting towers easier to use and more ecologically friendly.
The Hylite lighting tower from Taylor Construction Plant includes Adjustabeam technology which allows the user to adjust the direction of each lamp from the ground. The TCP Hylite also has a flexible framework design which allows 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 dramatically, which is very timely seeing as global warming is becoming a more and more prevalent concern.
