2250 MAX-ER 2000 OPERATOR’S MANUAL SET-UP AND INSTALLATION

MAST CAPACITIES FOR SELF-ASSEMBLY
AND DISASSEMBLY
Crane Requirements
The 2250 must be rigged as follows (see Figure 4-17):
• 130 ft (39,6 m) #44 Mast
• 169,200 lb (76 750 kg) Crane Counterweight
• 60,000 lb (27 220 kg) Carbody Counterweight
• 0 lb Wheeled Counterweight
• 360° Rating
Self-Assembly and Disassembly Capacities
Boom hoist equalizer #194343, weight box #194342, hook
#674137, and 10-part boom hoist reeving are used as lift
rigging as shown in Figure 4-17.
Capacities and operating radii given in Table 4-1 in
Figure 4-17 are for freely suspended loads and for self-
assembly and disassembly only. Capacities are based
on structural competence.
The weight of all slings and load handling equipment
beneath the hook is considered part of the mast load. The
weight of the equalizer, boom hoist reeving, weight box, and
hook are included in capacity determination.
Do not lower mast beyond radii where combined
weights are greater than rated capacity. Where no
cap acit y i s sh o wn , o pe rat ion is no t in ten de d or
approved.
Operating Conditions
The crane must be operated on a firm, level, uniformly
supporting surface with gantry in intermediate position as
shown in Figure 4-17.
The automatic mast stop must be adjusted for 80° maximum
angle as instructed in Section 6 of this manual.
The crane operator’s judgment must be used to allow for the
dynamic load effects of swinging, hoisting and lowering the
load, traveling, wind and other adverse operating conditions,
and the crane’s physical condition.
Crane must be operated in STANDARD mode (MAX-ER
mode off) to enable automatic mast stop which is set at
80°.
With STANDARD mode on, the following drums are used:
• DRUM 4 to raise and lower the mast with the boom hoist
handle on the left console.
• DRUM 2 to raise and lower loads with the left drum
handle on the right console.
Machine Travel
The crane must be traveled on a firm, level, uniformly
supporting surface with the mast within the mast angle range
given in Table 4-1. Travel may be limited depending upon
ground conditions.
Operating Radius
Operating radius is the horizontal distance from the crane’s
axis of rotation to the center of the vertical hoist line or
equalizer. Mast angle is the angle between horizontal and
the centerline of the mast butt and inserts, and is an
indication of operating radius. In all cases, operating radius
shall govern capacity.
WARNING
Falling Mast Hazard!
Do not operate mast above 75°. Mast may fall over
backwards.
Minimum mast operating angle is 35°.
