![]() ![]() The initial "container" is usually a type of reservoir (known as a "sump") located in the frame or base of the vehicle. More specifically, forklifts run on the power caused by moving oil as it is forcefully transmitted from one "container" to another by some sort of tubing or connecting system. Since hydraulic principles only apply to incompressible fluids, forklifts run by necessity on incompressible substances such as oil. Hydraulic power has been combined with forklifts since shortly after the First World War – or, in other words, almost from the beginning of their invention. These machines harness the pressure transfer described in Pascal’s Law to power virtually all aspects of their moving and lifting operations. Forklift DesignĪs indicated earlier, hydraulic systems are used for lifting power in most forklifts (although some companies today have developed electric actuator controlled lifts). Average yearly sales of a million forklifts across the globe testify to the importance of this machine in manufacturing today. Some significant developments of the latter decades (particularly the 1960s-1980s) included overall improvements in electronic controls and balancing capabilities. The 1950s saw significant developments in forklift design, including the use of battery power, designs for maneuverability in narrow spaces, increased vertical lifting capabilities, and safety cages to protect operators. In the decades following 1945, forklifts continued to gain new features and popularity. In the same way that the First World War triggered the creation of the forklift, the Second World War accelerated the development of the forklift as armies worldwide scrambled for ways to effectively transport staggering amounts of material. Another factor, ironically, was World War II. One factor that spurred the increasing production of forklifts was the creation of the standardized pallet in the 1930s. Thus, Yale is typically credited with inventing the first true forklift. In 1923, a company called Yale & Towne added forks and a mast that could exceed the height of the truck to this invention. One company named Clark began selling these machines (known originally as "Tructractors") as other companies started placing orders for them. At first, these machines were little more than tractors with attachments nevertheless, curious customers began taking notice of them. Facing manpower shortages, a couple of American companies invented mechanized lifting trucks to facilitate their operations around 1917. World War I triggered their invention due to sheer practical necessity. This scientific observation has come to be known as Pascal’s Law and forms the basis of all hydraulic systems.ĭespite Pascal’s discovery, forklifts as we know them today did not develop until well after the start of the Industrial Revolution. A consequence of this is that, under the aforementioned circumstances, liquid will escape through any existing outlets with the same pressure being exerted on it in the container. Pascal discovered that pressure exerted on an enclosed, incompressible liquid spreads equally to all areas of that liquid. The discovery of hydraulic power – the scientific foundation of forklifts – can be traced to the work of French scientist Blaise Pascal in the mid-seventeenth century (1647-1648). Things to Consider When Purchasing a Forklift.Since the vast majority of lift trucks do possess forks, the term forklift is sufficient and will be used for the purposes of this article. In a technical sense, a lift truck is more accurate since not every type of this machine possesses actual forks for lifting. Practically speaking, these terms are all interchangeable. This is designed to be inserted under loads and raised in order to move the load to a desired location.įorklifts are sometimes referred to as forklift trucks or simply lift trucks. Forklifts typically have a power-operated, moving forked platform attached to the front of the vehicle. Forklifts are industrial vehicles used in applications such as warehouse storing and distribution for the lifting, moving and loading of heavy products, materials and packaged pallets. ![]()
