Safety feature
Description
Illustration
Lifting limit switch
The lifting limit switch switches off
lifting movement in the winch at a
determined height. As a result, a
collision between the bottom hook
block and the pulley head is pre-
vented. Additionally, extending
and retracting are switched off.
Length indicator and angle indi-
cator
The length and angle transmitter
measures both the angle and the
length of the telescopic boom.
This is transmitted to the RCL. If
the length or angle of the tele-
scopic boom fall in the non-per-
mitted area, the RCL switches off
all load moment-raising machine
operations.
