Module 61 Support jacks
Certain machines are equipped with support jacks in order to in-
crease the capacity in the third container row. The support jacks
are controlled with a switch in the operator’s cab. A hydraulic cyl-
inder affects a linkage system which presses the support jack
down and thereby reduces the load center by 600 mm, which in-
creases the third row capacity.
As the support jacks have left their upper position, a red warning
lamp will light up simultaneously as the transmission is disen-
gaged. When the support jacks have reached the bottom position
a green lamp will light up. Furthermore, the overload safety sys-
tem changes load curve. As a result of this, the higher capacity
(+7 tonnes) in container row 3 can be utilized.
The upper and lower support jack positions are controlled by in-
ductive sensors which are connected to the overload safety sys-
tem.
If overload occurs, the support jacks can be lowered. On the con-
trary, the support jacks cannot be raised until the overload is neu-
tralized by disengaging the load or retracting the boom.
