The History of Creation of Cartable Lighting Tower
Who invented the 1st conveyable lighting tower?
This depends mostly on your definition of a lighting tower. A detailed 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 likely been used since the Stone Age.
In more current 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 could be the 1st machine of its kind filed in US patent 1934576 and is named as a transportable floodlighting unit for airports.
The patent describes a frame with 4 wheels at every corner ( allowing the machine to be towed ), a generator powered by an engine and one giant electrical lamp at each end of the vehicle. The machine is intended 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 harsh 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 conveyable lighting tower composed 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 does not 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 guarantee stability in high winds.
This is reasonably a big development in the history of the lighting tower as this patent principally forms the basis of most modern day lighting towers which contain similar elements such as a base that stores the engine and generator together with an extending hydraulic mast that supports the luminaries.
The subsequent patent was filed later on in the same year of 1980 but was for an answer to provide more intensive illumination. The US patent 4220981 describes a framework 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 electric lamps. The design also allows for the masts to be revolved enabling finer control over the area of illumination. By offering two masts the light tower also allows for illumination over virtually every side of the machine. This isn’t like prior light towers which often offer illumination on only one side of the machine.
Since 1980 substantial progress has been manufactured by lighting tower makers. Although the overall design has varied small from those seen in the 1980s many enhancements have been made to make lighting towers better to use and more ecologically 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 frame design which allows just about any generator to be used to power the light heads.
The TCP Ecolite lighting tower in addition has broken new ground by using 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 prevalent concern.
