Relieving the Load on Bearing Points
NOTE: The weight of the lattice extension can cause the
bearing points on the left side to be misaligned or
the pins to get weighted which makes it impossible
to knock them out.
When establishing or disconnecting the connections,
proceed as follows:
• Lower the lattice extension until it is on the ground with
the supports (Figure 4-19). If necessary, override the
lifting limit switch.
• Continue to lower carefully until the connecting points
(Figure 4-20) align or until the load has been removed
from the pins.
