<h1>Hydraulics for Truck Bodies</h1><strong> Author: <a href='http://www.articleseen.com/profile_James Handrousen.aspx'>James Handrousen</a></strong><br /><p>There are several industries that use hydraulic truck bodies in their day-to-day activities. Not only do construction companies use dump and crane bodied trucks, but other industries such as delivery companies and power line repairmen use these trucks everyday. Electric companies usually add a hydraulic crane attachment to their trucks, lifting their worker high into the air to reach power lines and high-rise buildings. Other companies, such as waste management companies and construction companies, use a hydraulic dump body on their trucks, so they can haul heavy loads between sites. In this articles, we will discuss hydraulic systems and the dump bodies they support. While each hydraulic body system is going to be a bit different, there are many similar features. For instance, dumpers are fitted with large containers to transport materials. Each type of truck is different, though, depending on the material that needs transport. Heavy items need more support and hazardous materials needs extra precautions. In certain cases the trucks and dumpers are fitted with the hydraulic systems to lift the weights. Every hydraulic system is made up of four main items: a control valve, a pump, hydraulic fluid, and a piston/cylinder system. In a hydraulic system, these parts work together like the human body. The control valve, pump, and piston/cylinder arrangement are like the circulatory system and the hydraulic fluid is like the blood. Once started, this system circulates the fluid all over the truck body, performing tasks required of it. Turning on the hydraulic system is easy. In the truck's cab, there is usually a switch that will operate the system, causing the machine to start up and get going. Have you heard of hydraulic force? Well, that is the force exerted on the hydraulic fluid by the motor at the time of activation. Once that fluid is pressurized, it's time for step two. This high pressure hydraulic fluid is then directed by the control valve towards the piston and cylinder arrangement. For heavy loads and larger operations, the hydraulic systems are set up with two piston/cylinder sets. Though for smaller operations and lighter loads, only one set is required. The piston is a sort of long rod and it moves inside the cylinder in linear direction. How high can the piston lift? Well, that depends on the length of the cylinder and the piston itself. The truck body starts lifting after the piston starts moving. The piston starts moving because the pressure from the hydraulic fluid is transferred to it through the control valve. And the motor starts it all. The de-energized hydraulic fluid escapes from the other side of the cylinder to the reservoir. To maintain the continuous lift-up of the piston the high pressure fluid is pumped continuously to the piston and cylinder arrangement. It absorbs the energy in the hydraulic pump or motor and delivers the energy to the piston and cylinder, which is also called actuator. The important thing is to build the system correctly, so no pressurized hydraulic fluid can escape the actuator before the energy has been transferred. Wasted energy is never a good thing, especially if it breaks down a hydraulic system. Hence the oil seal between the intact piston and cylinder is vital. In fact, if your hydraulic system is having problems, check the oil seals. If these wear down, the whole system fails. So, the hydraulic fluid provides energy. But it also lubricated the other parts of the system, so they run smoothly. Because of the coating properties of the hydraulic fluid, things stay well lubricated but there is also a bit of fluid loss for energy transferring purposes. To ensure a working system for years to come, a small amount of hydraulic fluid should be added to the system at regular intervals. This way, everything runs properly. Trying to understand everything about the hydraulic system can be difficult. But perhaps understanding the operation will cause you to look at these systems differently in the future. </p><strong>About the Author:</strong><br />Need more info about hydraulic truck and <a rel="nofollow" href="http://www.articlesnatch.com/Article/Hydraulic-Dump-Bodies-Explained/1176613">dump bodies?</a> James Handrousen can suggest supplemental resources for you.<p> Article Source: <a href='http://www.articleseen.com/Article_Hydraulics-for-Truck-Bodies_19962.aspx'> http://www.articleseen.com/Article_Hydraulics for Truck Bodies_19962.aspx</a></p>
