3.3 RATED TOTAL LOAD CHARTS M A E D A Crawler Crane
3-16 5/2020 CC1908S-1
DANGER
• When using the Searcher Hook, the Moment
Limiter "Number of falls" setting must be set
to Searcher Hook mode, and select Searcher
Hook offset position.
• When using the Searcher Hook Winch, the
Moment Limiter "Number of falls" setting
must be set to Searcher Hook Winch mode.
•Before start working, always make sure the
Moment Limiter is correctly set to the actual
working condition.
WARNING
• The rated total load is based on the level and
hard ground.
•The fly jib operation is only allowed in
stationary position.
•When the boom length in use exceeds the
boom lengths shown in the Rated Total Load
Chart, always operate in accordance with
the capacities shown for the next higher
boom length.
•Deductions from Rated Total Loads must be
made for the weight of : hook
block(standard : 20kg), ball/hook, slings,
rigging or other suspended gear.
1. This Rated Total Load Chart shows
maximum allowable capacities. These rated
total loads are based on the machine
standing level on a firm ground support
surface, under ideal job conditions and a
freely suspended load.
2. Sufficient design tolerance must be used to
ensure adequate ground support surface
design. The rated total loads are for static
conditions only, and do not include dynamic
effects of swing, extending, retracing,
lowering, raising, wind or adverse conditions.
Crane users must reduce Rated Total Loads
ratings to take all conditions into account.
3. The load radius shown in the Rated Total
Load Chart is based on practical load radius
including boom deflection due to loading. The
Crane user must calculate and compensate
for boom deflection as the load is lifted.
4. Deductions from Searcher Hook Rated Total
Load must be made for the weight of the fixed
hook(3kg), the ball hook(20kg), and all
rigging.
5. Crane users must consult the Operators
Manual for complete details about assembly,
operation, maintenance, configuration, and
its limitations. Modifications to the crane,
other than what is specified or supplied by the
original equipment manufacture, can result in
a reduction ofrated total load ratings.
6. The Working Range Chart dose not include
boom deflection.
7. The moment limiter, sometimes, may display
a bigger actual load value than the total lifted
load, due to rounding up of the display.
8. RESTRICTED AREA : At high boom angles,
the E-Boom (arm) and the hook may interfere
with each other. To avoid this interference : In
SH1 position, do not operate above 35
degree boom angle. In SHW positiom, do not
operate below 30 degree boom angle.
9. Normal Searcher Hook lifting operation is
between 0 to 80 degree boom angle.
10. You can extend/retract boom with a load.
11. Do not use the Searcher Hook and the Hook
Block/Ball simultaneously to hoist load.

USAGE PRECAUTIONS
WARNING
• Be sure to change the setting after
mounting or removing the searcher hook to
the main unit. Using the machine without
changing the moment limiter setting may
result in a serious accident, such as
damage to the machine or the machine
tipping over.
• Be sure to use the searcher hook with the
actual position and the monitor position
settings matched. Failure to do so may
result in a serious accident, such as
damage to the searcher hook or the
machine tipping over.
•When using the winch with the searcher
hook, be sure to replace the wiring
connected to the overwinding detector on
the main boom side to the searcher hook
side. If the wiring is not properly connected,
the moment limiter and overwinding
detection device may not operate properly,
resulting in a serious accident.
• Make sure that the searcher hooks and
brackets are securely pinned. Make sure
that the linch pin is also securely set to
prevent the pin from falling out.
• When using the searcher hook, always set
the engine to low idle and operate the crane
at a micro speed. Sudden lever operation
may cause excessive force to be applied,
damaging the searcher hook and causing a
serious accident.
• Incorrect operation of the searcher hook
may cause deformation of the bracket or E-
boom, cracks in the welds, etc., which may
cause the searcher hook to fall off. Before
starting work, be sure to inspect each part
of the searcher hook to make sure there are
no deformations or cracks in the welds.
• See "Chapter 2: Safety" for more
information on precautions other than those
indicated in this section.

MOUNTING AND REMOVING
WARNING
• Read and understand the instructions
carefully before you start the process.
•Once the machine is in the working
position, stop the engine and perform the
work. Work during machine running may
result in malfunctions or serious accidents
due to unforeseen movement.
•The searcher hook should be used with the
main hook removed.
•The mounting, stowing, and removal of the
searcher hook should be performed on a
level and firm surface with the main boom
set to level.
•Use a crane to mount, stow, and remove the
searcher hook.
•Use a stable workbench with sufficient
height when working. Using an unstable
workbench can cause you to fall from a
height and cause a serious accident.
• Do not work on the crawler.
• Do not get into a position where you will be
under the searcher hook while working.
•Do not put your finger in the pinhole.
•Do not put your fingers between the boom
head and the sheave head and the E-boom.
•Be sure to insert the position pin from the
top in the correct position and secure it with
the linch pin.
5.10.3.1 MOUNTING SEARCHER
HOOK
WARNING
When mounting the searcher hook to the
main unit, be sure to set the searcher hook
setting to "With Searcher Hook". Using the
machine without changing the moment limiter
setting may result in a serious accident, such
as damage to the machine or machine
tipping.
Mount the searcher hook according to the below
procedure.
1. The machine should be in the below
position:
Move the machine to a level surface.
Make the boom fully retracted.
Set the boom angle to 0°.
2. Attach the bracket (1).
Once the holes for the main boom head and
bracket (1) are in place, insert the position
pins (A1) into the 4 positions from the top.
Securely lock the position pins (A1) with the
linch pins (L).
The bracket (1) must be lifted by a crane for
mounting. To lift it, set the sling to the hook at the
top of the bracket.
Add.

5.10 SEARCHER HOOK (OPTION) M A E D A Crawler Crane
5-80 5/2020 CC1908S-1
WARNING
When mounting the bracket, pay attention to
the hole position and the mounting position
to be used.
3. Install the E-boom (2) on the bracket (1).
Once the holes for the bracket (1) and E-
boom (2) have been positioned, insert the
position pin (A2) into the two positions.
Securely lock the position pin (A2) with the
linch pin (L).
Be careful not to install the E-boom (2) in the
wrong direction. Install it so that the stopper
or harness guide is at the bottom.
4. Install the boom head (3) on the E-boom (2).
Once the holes for the E-boom (2) and boom
head (3) have been positioned, insert the
position pin (A3). Securely lock the position
pin (A3) with the linch pin (L).
5. Install the shackles (4) and swivel hook (5)
on the boom head (3).
At this time, put washers (6) between the
boom head (3) and the shackles (4).
DANGER
Do not use the swivel hook at the shackle
section for stowage.
The shackle section for stowage is not
strong enough. Using this may lead to
serious accidents, such as dropping the load
due to damage to the boom head or E-boom.
6. Remove the hook block and wire rope from
the boom head
For the removal procedure, refer to steps 1
to 9 of "6.18.1.4 [1] Removal of Winch Wire
Rope" on P.6-79.
Add.

M A E D A Crawler Crane 5.10 SEARCHER HOOK (OPTION)
5/2020 CC1908S-1 5-81
7. Wind the wire rope with the hook raising
operation until it comes off the guide roller at
the bottom of the boom.
8. Secure the end of the wire rope (31) to the
wire socket (32).
Pass the wire rope (31) through the wire
socket (32), put the rope wedge (33) in
position (a), and then pull the wire rope (31)
strongly in the direction of the arrow.
Install the wire clip (34) with the following
dimensions.
9. Fold the stowage rubber (7) in half and pass
it through the guide roller and wire socket on
the underside of the boom before hooking it.
10. Slide the hook stowage lever downward and
wind the wire rope until the stowage rubber
(7) is slightly taut.
Use the hook stowage lever to reel in the wire
rope. Be careful not to wind up too much, as
the stowage rubber (7) will be cut off.
11. Select "With Searcher Hook" in the searcher
hook setting on the user setting screen of
the monitor.
12. Set the searcher hook setting on the user
setting screen of the monitor to "Winch
OFF".
