Weighing systems General Information
Mobile weighing technology
Mobile weighing technology means integrating weighing systems into industrial trucks with the aim of being able to weigh the load directly. Using mobile weighing technology eliminates the need for stationary scales. This means no additional travel distances, no waiting time at stationary scales, less energy consumption and a lower risk of accidents.
In order to determine the right weighing system for your logistics process, it is important to know in advance what you want to weigh and with what level of accuracy. It should be noted that the specified system accuracy can deviate both upwards and downwards. The display steps set in the display device are related to the system accuracy.
Griptech is certified to build its own calibratable systems and to carry out the initial manufacturer certification for both non-automatic scales (NAWI) and automatic scales (AWI hydraulic weighing system) for new devices. A calibratable weighing system is not necessarily more accurate, but the deviations must meet certain tolerances. A calibrated system is required if you sell by weight and the weight cannot be verified. We ask that you check with the local calibration authority whether a calibratable weighing system is required.
Weighing systems based on electronic load cells
Griptech builds and supplies mobile weighing systems based on electronic load cells with integrated strain gauges, which are mounted in the structure and the determined weight is shown on a display. These systems are very accurate with an accuracy of up to 0,1% of the weighed weight. However, the load cells are generally relatively sensitive to impact forces. The calibrated systems are available as non-automatic scales according to Class III up to 3000 parts.
Hydraulic weighing systems
Griptech also produces and supplies hydraulic weighing systems, which determine the weight using the hydraulic pressure of the lifting unit. These weighing systems are robust, very stable, weigh independently of the load's center of gravity, have no influence on the residual load capacity and can be used in combination with attachments. They are also suitable for large forklifts and reach stackers with a load capacity of up to 100 t.
With hydraulic weighing systems, the accuracy is determined as a percentage of the vehicle's load capacity. Griptech builds and supplies the most accurate and also the first calibratable hydraulic weighing system for forklifts in this accuracy class, with a system accuracy of up to 0,1%. As a calibratable automatic scale (class Y(a)), the system offers an accuracy of up to 1150 parts. With a hydraulic scale, the load always has to be moved up, down or in both directions. These systems are less suitable for order picking.
All hydraulic weighing systems can only to Installation must be calibrated.
Combination with attachments
Griptech is able to supply the mobile weighing system with the right accuracy for almost any application. Both the load cells and the hydraulic weighing systems are designed for rough everyday use. The use of only high-quality components results in little maintenance and a long service life. Griptech builds various attachments such as tine adjustments or rotators with load cells integrated into the design.
Display device and data processing:
The load cells generate an electrical signal that is passed on to a display device, where the measurement signals from the weighing sensors are converted into a visible weight. Griptech develops and builds its own display devices and sometimes uses display devices available on the market depending on the desired functionality and data processing. We also supply special designs, such as ATEX, cold storage design, stainless steel housing and other special solutions.
For you as a customer, the weighing system is a means of making the weight of the load visible. However, it is becoming increasingly important to pass the weight on to an inventory management system. In this area, the options are varied and customer requirements are often very specific. We are able to determine the weight, record a lot of additional information and pass this on to your inventory management system in a specific format.
You can recognize weighing systems that are suitable for calibration by this seal:
The possibilities include:
- Printing the weighing data via a thermal or label printer.
- Cumulation of several weighing processes.
- Piece counting function.
- Product name memory with weight input for piece counting.
- Enter product coding or store it using a scanner.
- SmartBox for data storage (alibi storage) and transfer.
- Data transfer via RS232 cable, WLAN, Bluetooth, 3G or 4G
Assembly:
Griptech has a team of service technicians who install and calibrate hydraulic weighing systems on vehicles both on site at the customer's premises and at the head office. For calibrated systems, it is cheaper and better to carry out the installation at our head office in Herzogenrath.
