Since from the beginning of time, man has been using machinery and tools to improve his quality of life and perfecting work efficiency. We are the only species on earth with the intelligence to design and implement tools that are able to assist us in our daily tasks. Over the past generations, technological advancements have improved the tools we use today, and have continuously revolutionized industries through each generation, in particular those of the past 150 years. The hydraulics industry in particular can be credited with significantly impacting and changing the face of human machinery forever. Hydraulic systems are tools and machines that rely heavily on high pressure liquid power to fulfill its functions. The state of purity of this liquid is crucial to be able to perform its purpose, which means the hydraulics liquid has to be run through an oil distillation system to filter out any impurities. Various motors and cylinders will transmit the liquid through control valves, tubes and hoses to the motors and cylinders. Many machinery used in performing serious functions in everyday use uses hydraulics to function. Bulldozers, referred to as crawlers move by using rigid plates that are joined to each other set on wheels, using continuous tracks. The function of this track movement is to allocate the machine’s mass over a larger surface than mere wheels would allow for. The bulldozer is geared with a dozer blade. The term ‘bulldozer’ refers to a tractor equipped with a dozer blade. This blade is utilized in moving debris, sand and soil, especially in construction work. In the first bulldozers, its blade was controlled by a brake, or winch system. They are now fitted with hydraulic cylinders, allowing much more exactitude in the blade’s operation. Another piece of machinery which uses hydraulics in its function is a backhoe. It is a kind of excavating tool commonly referred to as a digger. In essence it is a tractor, fitted with an articulated arm with a digging bucket at the end, used in excavation scenarios. The arm which is closest to the vehicle is referred to as a boom, and the other part of the arm is the dipper. The bucket and the arm are powered by sophisticated and highly developed hydraulics that allow for accurate movement. Forklifts are powered by hydraulic systems as well. Such machines are powered by industrial trucks which are used in the lifting and transporting of heavy materials, especially moving and lifting pallets in warehouses and stock distribution centers. The mast of the forklift is what performs most of the work in raising and lowering the loads. It is obvious that hydraulics are used in our daily lives, even if we don’t see it in our every day.
