Machinery with a maximum working load of not less than 1 000 kilograms or an overturning moment of not less than 40 000 Nm must be fitted with devices to warn the driver and prevent dangerous movements of the load in the event of:
- overloading the machinery:
- either as a result of maximum working loads being exceeded, or
- as a result of the moments due to the loads being exceeded,
- the moments conducive to overturning being exceeded as a result of the load being lifted.
