Installing the Fixed Mast Top
NOTE: Prior to installing the fixed mast top, the mast must
be blocked. The mast butt cannot support the
entire weight of the mast.
See Figure 4-50
for the following procedure.
1. Block the fixed mast. The approximate minimum block
height (1) is 900 mm (35.43 in).
2. Make sure the SL 6 slings are still attached to the mast
top (2) at the permanent lifting shackles (3) and at the
lifting link (4).
3. Reattach the slings to the assist crane.
4. Lift the mast top into position at the end of the second
mast insert so the fixed pins on the mast top engage the
hooked connectors.
5. Remove the safety pins (5) and slide the retaining
pins (6) out.
6. Lower the mast top until the bottom connection holes
align.
7. Slide the retaining pins in to attach the mast top to the
insert.
8. Install the safety pins.
9. Disconnect the slings from the mast top and from the
mast butt.
