The Evolution of the Screw Jack

ziviso

Screw jacks are a type of lifting mechanism that use a screw to lift heavy loads. They have evolved over the centuries from their original design by Archimedes in 200BC to the modern screw jack we know today. They are used in a variety of applications, including the construction of bridges, railroad industry, truck loading platforms, hospital beds, dentist chairs, roller-coasters, football stadiums, aircraft air bridges, jumbo jets, and many more. Screw jacks have become a popular choice due to their precision, efficiency, reliability, and ease of operation. They can lift, push, pull, lower and position loads ranging from a few kilos to hundreds of tonnes. Moreover, with the advances in technology, precision ball screws, and roller screws, they have become a real alternative to hydraulics in terms of duty cycles and speed. They are cleaner, quieter, and more reliable solutions, making them a popular choice in industries worldwide.

History of Screw Jacks

Screw jacks have been around for centuries, with evidence of their use in the Ancient Roman world. However, it was Leonardo da Vinci in the late 1400s who first demonstrated the use of a screw jack for lifting loads. His design featured a threaded worm gear, supported on bearings, that rotated the turning of a worm shaft to drive a lifting screw to move the load. Joseph Whitworth, a mechanical genius of the early 1800s, recognised the need for precision in industry. His work on screw cutting machines, accurate measuring instruments, and standards covering the angle and pitch of screw threads, would most influence the industry today. Whitworth's tools had become internationally famous for their precision and quality and dominated the market from the 1850s. In the late 1800s, Frank Henry Sleeper designed a lifting jack based on the principle of the ball bearing for supporting a load and transferring rotary motion, through gearing and a screw, into for moving the load. The device was efficient, reliable, and easy to operate. It was used in the construction of bridges, but mostly the railroad industry, where it was able to lift locomotives and railway cars. Local Coaticook industrialist, Arthur Osmore Norton, spotted the potential for Sleeper's design and in 1886 hired the young man and purchased the patent. The “Norton” jack was born. In 1928, The Duff Manufacturing Company Inc. merged with A.O Norton to create the Duff-Norton Manufacturing Company, which became the largest manufacturers of lifting jacks in the world. With the aid of the relatively new portable compressor technology, users now could move and position loads without manual effort. The jack incorporated an air manufactured by The Chicago Pneumatic Tool Company. Only ten years later in 1940, the first worm gear screw jack was offered by Duff-Norton for adjusting the heights of truck loading platforms and mill tables.
