crossmembers from back of truck frame. If AF is too short,
the frame will have to be lengthened. Use channels
fabricated from 100,000 psi (758 MPa) yield material that are
the same size as the truck frame. Weld these channels to the
ends of the existing truck frame channels. Bevel the ends of
the channels to get 100% weld joints with Grade 90 weld
material. Fabricate an inner channel of the same thickness
as the truck frame channels to span the weld joint for at least
12 in (30 cm) on each side of joint. Plug weld this channel to
the inside of the truck frame, then skip weld the inside edge
of the top and bottom flanges to the truck frame flanges
MOUNTING THE CRANE
Make sure the truck has been configured to meet the
minimum truck, PTO, and frame strength requirements as
described on page 9-2 through page 9-23. Mounting the
crane to the truck frame is as follows:
• Position the torsion box (T-box) on the truck frame.
• Mount the frame assembly on the T-box and secure to
the truck frame.
• Mount the front and rear outrigger boxes and secure to
the truck frame (RM Configuration).
• Install the RSOD (BC Configuration).
• Install the boom rest on the T-box and rear bumper on
the truck frame.
• Mount the operator stations and install the foot throttles.
• Install the boom, lift cylinder, and hoist.
• Connect the slew potentiometer.
• Connect the electrical interface.
• Install the hydraulic system.
• Complete the initial crane run in procedure.
• Calibrate the RCL and do the stability test.
NOTE: Unless otherwise specified, use the tables in the
section titled
Fasteners and Torque Values ,
page 1-7 to torque all bolts.
Set the T-Box
On the BC configuration the front outrigger box is welded to
the T-box. On the RM configuration both outriggers need to
be secured to the truck frame with anchors.
1. Position the truck so that the truck frame is level.
2. Place the T-box on the truck frame as determined by the
configuration drawing and minimum truck requirements.
NOTE: The top and bottom T-box reinforcing plates must
e x t e n d p a s t t h e R S O D m o u n t i n g p o s i t i o n
(Figure 9-6). If this cannot be accomplished
because of a long cab to tandem (CT) dimension,
contact the factory.
If the T-box does not fit tightly against the truck
frame, clamp the T-box and truck frame together to
remove the gaps.
Mount the Turret and Torsion Box to the
Frame Assembly
Position the turret assembly and the torsion box on the frame
assembly so that the mounting bolts can be routed through
the plates attaching the assemblies to the frame (Figure 9-7
and Figure 9-8).
Turret Mounting
1. Position the turret assembly (Reference Table 9-1).
2. Install the standard SAE washer (10) against the head of
the 1-1/4 inch grade 8 stud (11).
3. Install the Direct Tension Indicator (DTI) crush washer
(9) with the bumps facing away from the SAE washer
(10), facing towards the hardened washer (8).
NOTE: Do not allow the DTI crush washer to turn during
tightening of fastener or damage may occur to the
bumps on DTI crush washer causing improper
tension.
4. Install the DTI hardened washers (8).
5. Install the bolt and washer assembly in the turret
assembly mounting holes.
6. Install the standard SAE washer (10) and nuts (14) on
top side of the turret and snug tight.
7. Install the bolt and washer assembly in the inner turret
assembly mounting holes.
8. Install the anchor retaining bracket (12), locating it inside
the frame channel (Figure 9-7).
NOTE: Cut the anchor retaining bracket (12) for the inner
anchor and neatly machine as necessary to fit
inside the truck frame.
DANGER
It is mandatory that swing bearing and crane anchor bolts
be inspected and re-torqued after the first 300 hours of
crane operation and every 500 hours thereafter. The bolts
may loosen and cause the crane to separate from the
carrier which will result in damage to the crane and
possible injury or death to personnel.
