• Provide indented claws or crane eyebolts on the load carrier to ensure that hoisting gear
• Load cells must never be overloaded. Put the load carrier down slowly for this reason.
• Adjust the existing overload protection to ensure that it can still reliably sense transfer of

General installation information

The installation conditions vary widely. The dead load of the load bearing implement can be
very low or relatively high. You might be dealing with a container, platform or a roller
conveyor. The following installation instructions can therefore only describe the general
procedures.
Always set up the load bearing implement on dummies in order to protect the load cells from
damage during installation.
The load bearing implement then only has to be raised a few millimeters from bracket to
bracket in order to position the compact installation unit. The following description of the
installation is based on this assumption.
Note
Maintenance-friendly design
When planning the layout, ensure that the load cells are easily accessible once they are
installed. Then you can replace the load cells as needed without having to remove the
installation units.

can be used safely.
With load cells of smaller rated loads in particular, there is a risk of stretching the load
cell bodies when attaching force transfer devices, e.g. when tightening locknuts.
the required load. The overload protection must permit a rise in weight unhindered until
the setpoint weight is reached.
ice.
bending moments, eccentric loads and transverse loads are disturbance variables.
These disturbance variables cause errors in the measuring result and can damage the
load cells and installation units if the maximum limits are exceeded.
The mounting components normally allow so much room for movement that heat
expansion will not result in lateral loading.
