2250 OPERATOR MANUAL SETUP AND INSTALLATION
Assembling Upper Counterweight (Series 3)
See Figure 4-32 for the following procedure.
1. If lowered, raise the counterweight lifting frame and pin
in the operating position (see View F).
2. Lift the center box into position on the lower tray (see
View A). Do not pin the center box to the lower tray.
This step is required to ensure that the counterweight
support lugs on the center tray do not contact the hooks
on the lower tray when the center box is lifted onto the
crane.
3. Lift the side boxes into position on the lower tray and
align the connecting holes.
4. Pin the side boxes to the lower tray and to each other
(see View D).
NOTE: Make sure to install the safety pins.
WARNING
Falling Load Hazard!
Avoid death or serious injury. Do not attempt to install or
remove the Series 3 counterweight assembly as a
complete unit. The lifting pendants, links, or lugs may
break, allowing the counterweight assembly to fall.
The series 3 counterweight assembly must be installed
and removed in two stages.
See the detailed Series 3 counterweight installation and
removal instructions for more information.
