History of Hydraulic Lifts
For as long as humans have been constructing tall buildings, they have relied on lifts to transport people and materials. Ancient Romans used rudimentary platforms lifted by ropes pulled by slaves, an early precursor to modern lifting technology. However, hydraulic power did not become part of the equation until centuries later.
The first significant breakthrough came with Joseph Bramah, who patented the hydraulic press in England. His invention revolutionized agriculture and later transformed the industrial world. Across Europe, hydraulic power became instrumental in operating trains, elevators, canal locks, rotating bridge sections, and cranes, marking the beginning of a new era in mechanical lifting.
Throughout the 19th and 20th centuries, inventors continuously improved lift designs, making them stronger and more adaptable. Initially, hydraulic lifts found their primary use in elevators. In 1846, Sir William Armstrong introduced the hydraulic crane, which became essential for lifting applications. The United States saw its first hydraulic elevator lift installed in New York in 1870, replacing earlier steam-powered lifts that relied on coal combustion.
Innovation in hydraulic lifts continued into the 20th century. In 1925, Peter Lunati patented the first fully hydraulic automotive lift, revolutionizing vehicle maintenance. By the 1940s, the growing number of lift manufacturers led to the formation of the Automotive Lift Institute (ALI), an organization dedicated to establishing industry standards.
The 1960s brought further advancements, including the scissor lift, patented in 1963 by Charles L. Larson. Around the same time, Kaspar Klaus of Germany developed the sidelifter, expanding the range of lifting solutions available. The 1980s saw engineers integrate technologies to create a hydraulic scissor-type car lift, while the year 2000 marked the introduction of the four-post hydraulic vehicle platform lift.
Today, the hydraulic lift industry remains a hub of innovation. While existing equipment continues to perform reliably, engineers persist in refining lift technology, striving to make lifts even stronger, more efficient, and easier to use.
How Hydraulic Lifts Work
All hydraulic lifts operate using the same fundamental principles. Rooted in the science of hydraulics, these lifts rely on the application of force to a hydraulic fluid, enabling the transfer of energy from one point to another.
As this energy moves through the system, it undergoes a multiplication effect, significantly amplifying the applied force. This characteristic makes hydraulics one of the most powerful methods for generating movement. The transferred energy powers the hydraulic cylinder within the lift, providing the necessary force to raise or lower an object with precision and efficiency.
