2. Place the climbing cylinders on the supports of
the lowermost guide frame (Fig. 1), insert the
lifting pins 1 in position "A" and secure. In this
position, the climbing cylinders can be
extended and retracted without the boom
column being lifted (for bleeding).
3. Extend the climbing cylinders slowly to the
limit top. The boom column and the placing
boom are raised in the process.
4. When the climbing cylinders are fully extended, insert a supporting pin 1 (Fig.
2) on both sides above the guide frame.
5. The safety latches 2 (Fig. 2) of the supporting pins
must be inserted into the next higher bore of the
boom column − Relieve the climbing cylinders by
retracting them slowly a short distance. The load of
the boom column and the placing boom is now
borne by the supporting pins.
6. Retract the climbing cylinders completely (Fig. 3).
7. Withdraw the lifting pins and insert into the
next hole (Fig. 3).
8. The next lifting procedure can now be started.
9. Repeat these steps until the boom column has
reached the desired height.
