Many companies benefit from the use of an excavator crane in daily business operations. It can perform various tasks for a variety of industries such as mining, electrical, and telephone, among others. Its main structural feature is a giant hydraulic auger mounted on the truck chassis. With so many technological advances, there is a tendency to forget the history of this specialized vehicle, how it was created and how it came to be.
Following is information on the original method of well drilling, the historical background of the derrick, and its current transformation to suit various industry applications.
original process
The labor intensive installation of power and telephone line poles is done with a conventional manual digging process. Workers use a traditional shovel and post hole digger with a long handle and a set of shovel-shaped metal blades. The digging process is initially simple, and difficulties arise as the hole gets deeper. The open blades are forcefully pushed into the ground, then closed and forcefully pulled upwards outward to dig and create the desired hole. It’s hard work on your back and you can only dig a few holes at a time.
Another traditional excavation method is with manual and electric augers, a slight progression from the use of shovels. The hand auger existed long before telephone and utility poles. It is made from a wide “T” steel bar with helical wings to produce accurate results; It is used in the construction of roofs at ground level. Electric augers have powerful torque to speed up the soil digging process and only require one or two workers to control the machine.
History
With the rapid advancement in technology, it was necessary to find a faster and more efficient way to install telephone and electrical poles. The industry needed a powerful machine to easily and quickly dig postholes to provide much-needed services to eager consumers. Terex Utilities took on this mighty job and in 1945 invented the first mechanical drilling rig, which was given the name “Tellect”. It was primarily used in the telephone and power line industries and required two workers to operate.
ongoing development
Since then, there has been continuous development with different models and configurations. There are variations associated with this machine including: a reverse gearbox; the Rite-Way bit storage stand that can provide continuous drilling directly under the boom; the Commander 1 series with double lift cylinders; a full line of Captain Series products; and the current Teleelect excavator cranes. All of these innovations have evolved from a simple soil digging method to more advanced technology to eradicate the labor-intensive manual digging method.
personalization
To add more versatility, many companies are adapting excavators to aerial equipment to make it a device that can perform multiple applications in a short period of time without many workers. It offers a good return on investment, increases productivity and completes tasks on time and without delay.
With the desire to improve the quality of life, many inventors seek to discover new technological innovations that can impact many lives, as exemplified by taking the simple task of manual digging and turning it into today’s sophisticated well drilling methods. Without innovation driven by a desire to lighten the burden of manually digging soil, the invention of the bulldozer might never have happened; It was made possible thanks to a great idea and help from the past!
