Hydraulic Arm

Hydraulic arms are often referred to as the robot arms or robotic manipulator arms that extend the flexibility and capability of certain work stations by means of improving the efficiency of transporting and processing parts. The robotic arms can be powered by various systems; the hydraulic arms are the robots that are driven hydraulically. The power system determines the power output of a robotic arm. With higher power output capacity, a robotic arm is able to handle heavier loads. Having excellent power output, hydraulic arms are commonly involved in heavy-duty operations in the general manufacturing industry.
 

Hydraulic Power System

A hydraulic power system is a system that generates a force to drive a device by transmitting the mechanical power from a power source with several interconnected hydraulic pipes. The power source in a hydraulic power system is usually a pump. In fact, a pump has become a standard build-in component of a hydraulic power system today. The hydraulic pipes that transmit the mechanical power are hydraulic cylinders that contain pressurized fluid. The circulation of the fluid inside the cylinders passes the power mechanically to an end device so that that device can do work on a load.

Hydraulic power systems are frequently incorporated with heavy-duty manufacturing equipment because they have greater flexibility than mechanical systems and electrical systems. What's more, the hydraulic power system is able to generate more power than other types of power systems of the same size. Therefore, a machine driven by a hydraulic power system can have a relatively compact size while maintaining performance. A hydraulic system also offers a more rapid and accurate response to controls; as a result, it is preferable in heavy industries.
 

Robotic Manipulator Arms

The robotic manipulator arms are commonly referred to as the robotic arms. Based on the way the machine is driven, it can be an electrical arm or a hydraulic arm, etc. A robotic arm is like a human arm; it is designed and made to perform works in replacement of human workers. A robotic arm is essentially comprised of joints and limbs like a real arm. On the end of a robotic arm, devices or machines can be mounted so that the arm can carry out certain works as required. The movement of a robotic arm is programmed and controlled by a computer.

A robotic arm is very flexible and versatile. A manufacturing robot arm often has three or more joints. The more joints the robot arm has, the less limited the movement of the arm is. A hydraulic arm in the manufacturing industry typically has two or three joints and each joint represents a rotation axis. With the rapid response ability of the hydraulic system, the robot arm can execute the command that is delivered through a computer. Since the movement, as well as the power output of the robot arm, is all directed and controlled by the computer, the robot arm is able to provide excellent precision and efficiency to the works.
 

Application

The robotic manipulator arms are widely applied in the general manufacturing industry and engineering field because of the precision and efficiency this type of machine can provide. The hydraulic arms are favored in the heavy-duty manufacturing industry in particular since they have excellent power output and rapid response to controls. They have been implemented in the assembly lines or material handling operations especially. The robotic arms in heavy-duty industrial applications commonly have four to six joints. The joints allow the hydraulic arms to perform a wide range of movement so that the works can be done faster can more accurately.
 

Advantages

Firstly, the hydraulic arms make the work done faster. In industrial applications, hydraulic robot arms work faster than human workers. The working speed of the machines is set and managed by the computer control systems; it is limited only by the mechanical capability of the machine; therefore, the robotic arms can work as fast as possible at full capacity at all times.

The hydraulic arms can also help cut the costs in production. The costs in production include equipment maintenance, human labor, safety control, material waste, etc. With the implementation of robotic arms, the cost of human labor and material waste can be effectively reduced. Though purchasing robotic arms is costly, the company still saves a significant amount of money in the long run since the labor cost is reduced.

The other crucial advantage the hydraulic arms bring about is the minimal errors. The robotic arms are precise and efficient machinery. They do not get tired or distracted after a long run of repetitive work as human laborers do. Also, the works are monitored by the computer control units constantly. Therefore, the potential errors can be excessively minimized.
