It's easy to think the equipment we depend on simply sprang into existence, fully formed. Yet, modern material handling equipment is the culmination of over a century of tireless innovation and experimentation by those who saw problems in our world and sought to create a solution.
The scissor lift is one such invention. Emerging at a time when workers had far fewer protections than today, this now commonplace machine revolutionized aerial lift equipment. Read on to discover how scissor lifts took material handling to new heights.
Ladder falls became such a serious concern that Swedish cities installed hydraulic lifts on the back of automobiles, giving workers a stable platform on which to work. These mobile elevated working platforms (MEWPs) relied on long hydraulic pistons with telescoping scaffolding to achieve height.
By 1963, Charles Larson believed he could improve on the design. His patent application described "an extensible lift mechanism for elevating a load.
Of his design, he wrote, "This invention relates to such mechanism including an opposed pair of scissor mechanisms, each of which includes a pair of scissor arms pivotally connected together, where relative pivotal movement of the arms accompanies extension of the lift mechanism."
With the approval of that application, the modern scissor lift was born.
In the second half of the 1960s, John W. Parker of California took Mr. Larson's design a step further. The original patent outlined a tow-behind model requiring a separate vehicle to move about. Mr. Parker helped devise a self-propelled scissor lift that used an IC engine for motive power. IC engines would remain the standard for the next 30 years.
In the mid-1970s, Parker’s Parkerlift scissor lifts and models like it from competitors JLG and MEC went into mass production. This style of MEWP scissor lift grew increasingly popular throughout the United States. Their success prompted many other equipment manufacturers to develop and produce their own models.
This period brought about near-constant improvements in the technology. MEC, for example, introduced their popular pothole protection system. Competitors raced to build larger and taller models. In the early 1990s, the first scissor lifts extending above 25 feet entered the market.
The turn of the millennium heralded new advancements in aerial lifting equipment. Improvements in electric motors and batteries brought about the world’s first hybrid scissor lifts. These models combined traditional lift hydraulics with new electric driving and steering. These lifts were easier to manage on the job site, making them popular as construction scissor lifts.
The first all-electric scissor lift entered the market in 2021. This model and others like it finally eliminated all hydraulic components, relying entirely on electric motors. All-electric models proved more environmentally friendly than their hydraulic counterparts.
Today, scissors lifts are more popular than ever. The diversity of models allows for both indoor and outdoor use. Advancements in technology have also extended heights, with some indoor models reaching almost 45 feet and their outdoor counterparts closing in on 60 feet.
As scissor lifts gained popularity, accident reporting revealed a need for universal safety standards for all MEWPs. In 2020, the American National Standards Institute (ANSI) introduced standard A92.20. It established several new requirements for scissor lift manufacturers, including live load sensors, increased testing standards, and taller guard rails. Furthermore, standard A92.24 established the requirement for training aerial equipment operators, occupants, and supervisors to improve scissor lift safety.
Established in 1919, The Lilly Company predates even the earliest scissor lifts. Our history took us from the painting industry to the ice industry and, by 1952, into the material handling industry.
