hydraulic crane project synopsis pdf
A hydraulic crane is a type of heavy-duty equipment used for lifting and hoisting. Unlike smaller cranes, which rely on electric or diesel-powered motors, hydraulic cranes include an internal hydraulic system that allows the crane to lift heavier loads. This fluid-filled hydraulic system enables the crane to transport objects such as heavy shipping containers and tractor trailers, which are well beyond the size and scope of any other lifting device.
Each hydraulic crane consists of an enclosed operator's cab set atop a steel base. Some of these cranes may be set on wheels or rollers, while others are stationary. From the cab, the operator controls a large arm known as a boom. Many hydraulic cranes feature a telescoping boom, which allows the operator to reach objects from a greater distance. Cables and hooks attached to the boom can be fastened to different objects for hoisting or lifting.
The crane's engine powers a hydraulic pump, which applies pressure to an oil or fluid within the hydraulic system. Because oil can't be compressed, the oil transfers this applied force to other parts of the crane. By redirecting this force where its needed to lift an object, hydraulic systems help increase power and performance.
Hydraulic cranes are rated based on their total lifting capacity, which is a factor of both their construction and the strength of the hydraulic system. A 10-ton crane for example, can lift up to 10 tons (9,070 kg). Each hydraulic crane must be chosen carefully based on the demands of a specific project, and lifting a load that's too heavy will cause the crane to fail.
Different hydraulic crane designs allow users to more easily perform specific tasks. Those on tracks or wheels may be best suited to construction sites, while many shipyards and warehouses rely on stationary cranes. Smaller hydraulic cranes can even be found on board ships or even tow trucks.
Because of the large size and power of a hydraulic crane, all operators should undergo vigorous safety training to reduce the risk of accidents. A crane that suffers operational failures could put operators or those nearby at risk from fire or falling objects. Poorly trained operators may direct the boom into nearby buildings or even people. Cranes that have not been set up properly can even tip over, leading to large-scale damage. While not all areas require safety training, individuals or organizations often pursue training to minimize liability and maximize safety.
A ship is a busy place. When out to sea, naval, research, and fishing vessels pull or push heavy loads, like research equipment and crab pots, into and out of the water. But equipment and pots can weigh hundreds of pounds. So how does a ship's crew lift loads efficiently and accurately? With a hydraulic knuckle crane, of course. But what is hydraulics and why does hydraulics make certain tasks easier?
Hydraulics is the study of liquids and their mechanical properties: how they move, resist movement, act when subject to pressure, and so forth. In engineering, one application of hydraulics is using liquids, like water and oil, to move things. Why use a liquid to move things, instead of, say, air? One important reason is that a liquid is incompressible, which means that if you press on it, you cannot change its volume. For example, if you have a cup filled with marshmallows, you can fit even more marshmallows into the cup by compressing (squeezing) the marshmallows together. But if the cup is filled with water, you cannot fit more water into the cup - no matter how hard you squeeze! Because liquid is incompressible, applying a force (for example, a push or a pull) to one end of a hydraulic system transmits (moves) the force through the liquid to the other end.
Pressure is a force spread out over an area, or a force divided by an area. Pushing on the top of a glass of water, for instance, puts pressure on all of the water in the glass. Another way of thinking about pressure is to imagine pushing on an object with your finger or with the palm of your hand. In both cases, you are applying the same force, but the pressure is different because the area of the tip of your finger is much smaller than the palm of your hand. Figure 1 shows a simple hydraulic system that uses the concepts of force and pressure.
