1300A CRANE INSTALLATION
MOUNTING THE CRANE
Clamp On (Optional)
Make sure the truck has been configured to meet the
minimum truck, PTO, and frame strength requirements as
described on 1 through 15. Mounting the crane to the truck
frame is as follows:
1. Place the crane assembly on the truck frame as
determined by the information contained in the section
titled Positioning the Crane On the Truck on 10.
2. Saw the Anchor Retaining Bracket to fit the inside of the
truck frame (Figure 9-9).
3. Install the anchor bolts on the front and rear of the T-Box
frame as shown in Figure 9-9.
4. Torque the anchor bolts to 800 lb-ft.
5. Install the mid-mount anchor on the truck frame
(Figure 9-10). Check the fit of the J-bracket on the truck
frame and shim if required.
6. Torque the mid-mount anchor bolts to 100 lb-ft.
7. Bolt the rear bumper to the rear anchor bolts
(Figure 9-9).
DANGER
It is mandatory that swing bearing and T-box attaching
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.
