The Classification of Load Measuring Systems
Load measuring systems help to measure the weight of the raw materials in several industries. Besides measuring weights, these measuring systems are also useful for preventing overload and the detection of reliable load. Therefore, from heavy industries to high-temperature industries, load measuring systems have several applications. Whether it is about force and inclination measurement or about load torque limitation, we require load measuring systems. However, there are different types of measuring systems to measure the weight of the raw materials during lifting such as crane scales, dynamometers, load cells, and overload detectors. In this article, we will discuss different types of measuring systems and classify the measuring systems on the basis of the number of cranes involved.
Major Load Measuring Systems
You can find several types of load measuring systems available in the market. However, in this article, we will focus on the four most commonly used load measuring systems.
i) Crane Scales
Crane Scales help to measure the pressure and load on the crane. This measuring system consists of a 90-degree offset and a bottom hook. In many industries, crane scales are used for general weighing.
ii) Dynamometers
Apart from general weighing like crane scales, dynamometers have other applications such as for the monitoring and measurement of tension. The design of the dynamometers involves a 90-degree offset between the top and bottom shackle holes so that it becomes integrated into a suitable structure. You can use the 2 wheel drive dynamometer for vertical, horizontal, and any other orientation.
iii) Load Cells
Although there are some similarities between load cells and dynamometers, load cells do not have a digital indicator. The user will have the facility of voltage modulation, current modulation, and an analog signal. In general, people use these systems in arrangement with programable logic controllers and other similar devices.
iv) Overload Detectors
Overload detectors are electro-mechanical measuring systems that help to detect the overloads as well as underloads. The most interesting thing about these measuring systems is that these systems do not involve complicated control systems. Any overload or underload can cause the activation of the alarm. These systems also include emergency stops and other logic-based control systems.
Classification of the Load Measuring Systems
Based on the involvement of the cranes, load measuring systems can be classified into two groups such as
i) Single Point Load Monitoring System
When there is a load monitoring system below the hook of a single crane and the system measures the load of the lifted material, the load monitoring system is known as a single point load monitoring system.
ii) Multi-Point Load Monitoring System
A multi-point load monitoring system is used to measure the weight of the super heavy loads that require lifting through multiple cranes. In order to manage the lifts of complex multi-crane, multiple load cells perform in a harmony in this system. There is also advanced software in this monitoring system in order to display the real-time load map and measurements of weights. A multi-point monitoring system can also monitor the individual weighing stations. For these reasons, these measuring systems have significant applications in heavy industries.
