Install Counterweight
Refer to the Counterweight Assembly Drawings at the end of
this section for the total number of carbody and upperworks
boxes required for each counterweight arrangement.
Counterweights may be fabricated or cast (Figure 4-25
,
Views A, F).
NOTE No counterweight — carbody or crane — is
required to raise the fixed mast.
Install Carbody Counterweight
See Figure 4-25, View A for the following procedure.
The carbody counterweight can be installed with the live
mast. The crane must be in the following configuration to
install the carbody counterweight:
- Mast arms fully raised. Mast will be at approximately
107° (mast arms supporting mast) when attaching
carbody counterweights.
- Crane setup mode selected and confirmed.
- 360° swing permitted while handling counterweight.
- Live mast operated at radius no greater than 26 ft
(7,9 m) (approximately 150°) while installing
counterweight.
- Capacity at maximum allowable radius limited to
120,000 (54 430 kg).
1. Attach legs of chain sling to lifting lugs (1, View A) on
counterweight tray (2).
2. Mast, swing, and hoist as necessary to position tray at
desired end of carbody.
3. Guide tray so hooked connectors (4) on tray engage
lugs on carbody.
4. Lower tray so that bottom of tray rests against carbody.
5. Attach legs of chain sling to lifting lugs (1) on
counterweight box (5).
6. Lower first box onto tray so it is centered between
alignment lugs. Lift only one box at a time.
Lifting lugs must face to front and rear of tray.
7. Position remaining two boxes (5), one at a time, on top
of first box.
Lifting lugs and side lugs will align boxes as they are
installed.
8. Repeat steps 1–7 for carbody counterweight on
opposite end.
Install Crane Counterweight
The crane (upperworks) counterweight must be installed with
an assist crane.
See Figure 4-25
, Views B, C, D and F for the following
procedure.
1. Attach chain slings to lifting lugs (6, View D) on
counterweight tray (7).
NOTE Inboard side of tray is cut out to prevent
interference with rotating bed jack.
2. Boom, swing, and hoist as necessary to position tray at
desired side of rotating bed (8).
3. Guide tray so top hooks (9, View B) engage fixed pins
(10) in rotating bed.
4. Lower tray so tray engages notches in pins (11, View C)
at bottom of tray and pin holes are aligned.
5. Install retaining pins (12, View C).
6. Remove chain sling.
7. Repeat steps 1–6 for tray on opposite side.
8. Attach lifting slings to lifting lugs (6, View D) or (16, View
F) on counterweight box (13 or 15). Lift one box at a
time.
NOTE For luffing jib prepared cranes, counterweight
boxes with links (14, View E) must be installed on
top of stack. These boxes are used for raising and
lowering luffing jib struts.
9. Lower first box onto tray so it is centered between
alignment lugs.
Lifting lugs must face to front and rear of tray.
10. Remove lifting sling.
11. Repeat steps 8–10 for first counterweight box on
opposite side.
12. Continue to install counterweight boxes, one at a time,
alternating from side to side until required number of
boxes is installed. Lifting lugs, steps, and cast pads will
align boxes as they are installed.
WARNING
Tipping Hazard!
To prevent crane from tipping:
• Install carbody counterweight before installing crane
counterweight.
• Remove crane counterweight before removing
carbody counterweight.
Falling Load Hazard!
To prevent counterweight from falling:
• Lifting lugs on individual components are intended to
handle only that counterweight or component.
