flat piece of material should be placed under the
flanged joint end of the mast; this will prevent the
risk of the mast sliding as it is raised to a vertical
position.

the pipeline on the column is able to connect to the
delivery pipeline from the concrete pump.
21. The flange connections are secured per
step 10.
22. The rigger climbs the mast and releases the
crane.
23. The column is now ready to accept the plac-
ing boom, either in one piece or having been split,
first the turret section and then the arm section.
(Refer to the instructions on mounting the boom)
Reference must be made to “Splitting the boom”
instructions, if the crane lift capacity is not suf-
ficient to lift the boom in one piece. All person -
nel ascending to the working platform must wear
suitable safety harness and fall arrest equipment.
The rigger must have direct communication at all
times (it is not acceptable for instructions to be
relayed by shouting down from the platform or a
third party relaying instruction).
