personnel hoists so workers can safely access those
areas of crane and attachment that cannot be reached
from ground. Adhere to all local, state and federal
regulations for handling personnel.
ASSIST CRANE REQUIREMENTS
An assist crane is required to install and remove parts. See
MAX-ER Weights in Section 1 of this manual to determine
the weight of the heaviest individual part to be lifted.
If desired, the MAX-ER mast can be used as a boom to
assemble and install the MAX-ER boom and wheeled
counterweight assembly.
If the mast will be used as a boom, see Mast Capacities for
Self- Assembly and Disassembly in this section for:
•
2250 Requirements.
•
Operating Conditions.
•
Lifting Capacities.
MAST CONNECTORS
The mast sections have FACT
connectors:
•
The top connectors are joined by fixed vertical pins that
hook into holes in the adjacent section.
•
The bottom connectors are joined by removable
horizontal pins.
IDENTIFYING BOOM/MAST COMPONENTS
Boom and mast sections are marked for proper identification
as shown in Figure 4-1, View A.
Boom straps and links are marked for proper identification as
shown in Figure 4-1, View B.
HANDLING COMPONENTS
Handle boom and jib components with care to avoid
damaging lacings and chords. Current production #44 and
#79 inserts are equipped with lifting lugs (in top chords)
designed to provide a balanced load and to prevent damage
during lifting.
The terms RIGHT, LEFT, FRONT, REAR used in this section
refer to the operator’s right, left, front, and rear sides when
seated in the operator’s cab looking forward with the crawler
motors to the rear.
When lifting lugs are not provided:
•
Lift against chords only, never against lacings.
•
Use nylon lifting slings. If wire rope or chain slings are
used, install protective covering (such as sections of
rubber tire) between slings and chords.
COUNTERWEIGHT REQUIREMENT
MAX-ER operation with the wheeled c ounterweight
assembly requires the following counterweight:
Crane — 169,200 lb (76 748 kg). See Crane Operator’s
Manual for crane counterweight installation procedure.
Carbody — 60,000 lb (27 216 kg). See instructions later in
this section for carbody counterweight installation procedure.
Wheeled — up to 462,000 lb (209 563 kg) depending on
crane capacity chart.
WARNING
Falling Load!
Lifting lugs may break when lifting two or more inserts with
lifting lugs on one insert,
Lift only one insert at a time.
