Overload protection system for manual boom extensions
In the EU and certain other countries, manual extension booms must only be operated with an
overload protection system, which includes a sensor unit between the load lug and the hook.
Danger!
The sensor unit must not be overloaded. This creates an acute risk of
fatality for the operator and others.
Do not use sensor units on hydraulic extension booms.
Maximum capacity 2,000 kg (4,400 lbs).
Operating modes can be set up on the mode selector switch:
Warning!
If the position of the operating mode selector switch doesn’t match
the installation status, the extension or the sensor unit may get
overloaded. The load may fall down. This creates an acute risk of
fatality for the operator and others.
Use the sensor unit only in the correct mechanical extensions and in accordance with the chosen
operation mode.
