CRANE/ATTACHMENT IDENTIFICATION
An identification plate is attached to the outside of the
operator’s cab (see Figure 1-1
) and to the attachment (luffing
jib and MAX-ER attachment) available for this crane.
The crane or attachment model and serial number are
provided on the plate.
For the exact location of the identification plates on your
crane and attachments, refer to the Nameplates and Decals
Drawing in Section 2.
CRANE ORIENTATION
The terms RIGHT, LEFT, FRONT, REAR used in this manual
refer to operator’s right, left, front, and rear sides when
seated in the operator’s cab looking forward.

• The carbody and crawler controls are on the front of the
carbody.
DESCRIPTION OF COMPONENTS
See Figure 1-2 for the following description.
The MAX-ER Attachment has a hanging counterweight
assembly which supplements the crane’s counterweight.
Added counterweight increases the crane’s capacity and the
amount of boom it can operate with while maintaining its
ability to travel and swing with and without load (see MAX-
ER Capacity Charts for swing and travel limitations).
The attachment consists of the following components
(Figure 1-2
):
Counterweight Tray (23) and Beam Assembly (26)
suspended from fixed mast (14) by straps (16) and lifting
cylinder (27) (pinned to counterweight tray). The beam
assembly and inserts (28) provide three operating positions:
• 36.1 ft (11 m Working Position)
Beam Assembly with No Inserts
• 42.7 ft (13 m Working Position)
Beam Assembly with One Insert
• 49.2 ft (15 m Working Position)
Beam Assembly with Two Inserts
Counterweight Straps (16) and Lifting Cylinder (27) which
suspend the hanging counterweight assembly from the fixed
mast. The cylinders automatically raise and lower the
hanging counterweight assembly in response to changes in
load (weight of lifted load and boom angle).
Load Sensing Pin (21) which monitors mast loading. The
pin sends electric signals to the crane’s programmable
controller.
Programmable Controller which operates the attachment’s
electric and hydraulic systems to automatically raise and
lower the hanging counterweight assembly in response to
signals from the load sensing pin and boom hoist control
handle.
Sensors which monitor cylinder pressure and stroke.
