5.1 Safety information/instructions
CAUTION
Damage to load cells through incorrect mounting
• 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
• Protect the gap above the overload protection from deposits of dirt and ice.
• The load must be introduced in the measuring direction of the load cell. Torsional and

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.
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, pressure piece sets and mounting plates 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.
