Mobile weighing systems

Mobile weighing technology means the integration of weighing systems in 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 routes, no waiting time on stationary scales, less energy consumption, lower accident risk.

To determine the right weighing system for your logistics process, it is important to know what you want to weigh with which accuracy. It should be noted that with the specified system accuracy, the deviation can occur both upwards and downwards. The display steps set in the display device are in proportion to the system accuracy.

Griptech is certified to build its own certifiable systems and to carry out the manufacturer's initial certification for both non-automatic weighing instruments (NAWI) and automatic weighing instruments (AWI hydraulic weighing system) for new appliances. An approved weighing system is not necessarily more accurate, but the deviations must meet certain tolerances. A calibrated system is required if you are selling by weight and the weight is not testable. If a legal weighing system is required, please consult the local authority.

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 design and the determined weight is displayed on a display device. These systems are very accurate with an accuracy of up to 0.1% of the weighed weight. The load cells are generally also 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

Furthermore, Griptech produces and supplies hydraulic weighing systems, which determine the weight via the hydraulic pressure of the lifting unit. These weighing systems are insensitive, very stable, weigh independently of the load center, 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 up to 100 t capacity.

In hydraulic weighing systems, the accuracy is determined as a percentage of the load capacity of the vehicle. Griptech builds and delivers the most accurate and also the first verifiable hydraulic weighing system for forklift trucks in this accuracy class, with a system accuracy of up to 0.1%. As an approved self-leveling scale (class Y (a)), the system offers an accuracy of up to 1150 parts. With a hydraulic balance, it is always necessary to move the load up, down or in both directions. For picking, these systems are less suitable.

All hydraulic weighing systems can only be calibrated after installation.

Combination with attachments:

Griptech is able to deliver 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 too little maintenance and a long service life. Griptech builds various attachments, such as fork positioner or rotating fork positioners, with load cells integrated in the design.

Display device and data transfer:

The load cells generate an electrical signal which is relayed to a display device where the weighing sensor measurement signals are converted to a visible weight. Griptech develops and builds its own display devices and uses partially available on the market display devices depending on the desired functionality and data processing. We also supply special versions, such as ATEX, cold store version, stainless steel housing and other special solutions.

For you as a customer, the weighing system is a means to make the weight of the load visible. However, it is becoming more and more important to hand over the weight to a merchandise management system. In this area the possibilities are manifold and the customer wishes are often very specific. We are able to determine the weight, to collect a lot of additional information and to transfer it in a specific format to your merchandise management system.

The possibilities include:

  • Accumulate multiple weighing operations
  • Piece counting
  • Product designation memory with weight entry for piece counting
  • Enter product code or store using a scanner
  • SmartBox for data storage (alibi memory) and transmission
  • Data transmission via RS232 cable, WLAN, Bluetooth, 3G or 4G


Griptech has a team of service technicians who assemble and calibrate hydraulic weighing systems on vehicles both at the customer's premises and at the headquarters. For calibrated systems, it is cheaper and better to perform the assembly at our headquarters in Herzogenrath.
