WARNING AND OPERATING INSTRUCTIONS

NOTES FOR LIFTING CAPACITIES

GENERAL

RATED LIFTING CAPACITIES apply only to the machine as
originally manufactured and normally equipped by TADANO LTD.
Modiﬁcations to the machine or use of optional equipment other
than that speciﬁed can result in a reduction of capacity.
Hydraulic cranes can be hazardous if improperly operated or
maintained. Operation and maintenance of this machine must be
in compliance with information, in the Operation and Mainte-
nance Manual supplied with the crane. If this manual

is missing,

order a

replacement through the distributor.

SET UP

Rated lifting capacities on the chart are the maximum allowable
crane capacities and are based on the machine standing level on
ﬁrm supporting surface under ideal job conditions. Depending on
the nature of the supporting surface, it may be necessary to have
structural supports under the outrigger ﬂoats or tires to spread
the loads to a larger bearing surface.
For outrigger operation, outriggers shall be properly extended
with tires free of supporting surface before operating crane.

OPERATION

Rated lifting capacities based on crane stability are according to
ISO 4305.
Rated lifting capacities are based on actual load radius increased
by boom deﬂection.
The weight of handling device such as hook blocks,slings,etc.,
must be considered as part of the load and must be deducted
from the lifting capacities.
Rated lifting capacities are based on freely suspended loads and
make no allowance for such factors as the effect of wind,sudden
stopping of loads, supporting surface conditions, inﬂation of
tires, operating speeds, side loads, etc. Side pull on boom or jib
is extremely dangerous. Such action can damage the boom, jib
or slewing mechanism, and lead to overturning of the crane.
Rated lifting capacities do not account for wind on lifted load or
boom. We recommend against working under the condition that
the load is out of control due to a strong wind. During boom
lift,consider that the rated lifting capacity is reduced by 50%
when the wind speed is 9m/s to 12m/s; reduced by 70% when
the wind speed is 12 m/s to 14 m/s. If the wind speed is 14 m/s
or over, stop operation. During jib lift, stop operation if the wind
speed is 9 m/s or over.
Rated lifting capacities at load radius shall not be exceeded. Do
not tip the crane to determine allowable loads.
Do not operate at boom lengths, radii,or boom angle, where no
capacities are shown. Crane may overturn without any load on
the hook.
When boom length is between values listed, refer to the rated
lifting capacities of the next longer and next shorter booms for
the same radius. The lesser of the two rated lifting capacities
shall be used.
When making lifts at a load radius not shown, use the next
longer radius to determine allowable capacity.
Load per line should not exceed 6,600 kg for main winch and
auxiliary winch.
Check the actual number of parts of line with AUTOMATIC
MOMENT LIMITER (AML-E2) before operation. Maximum lifting
capacity is restricted by the number of parts of line of AUTO-
MATIC MOMENT LIMITER (AML-E2). Limited capacity is as

determined from the formula, Single line pull for main winch
6,600 kg × number of parts of line.
The boom angle before loading should be greater to account for
deﬂection. For rated lifting capacities, the loaded boom angle
and the load radius is for reference only.
The 12.8 m boom length capacities are based on boom fully
retracted. If not fully retracted

[

less than 17.6 m boom length

]

use the rated lifting capacities for the 17.6 m boom length.
Extension or retraction of the boom with loads may be attempted
within the limits of the RATED LIFTING CAPACITIES. The ability
to telescope loads is limited by hydraulic pressure, boom angle,
boom length, crane maintenance, etc.
For

lifting

capacity

single

top,

deduct the weight of the load

handling equipment from the rated lifting capacity of the boom.
For the lifting capacity of single top, the net capacity shall not
exceed 6,600 kg including the main boom hook mass attached
to the boom.
When

the base

jib

or top jib or both jibs are dismounted,

set

the

jib

state

switch

the DISMOUNTED position.

When erecting and stowing jib, be sure to retain it by hand or by
other means to prevent its free movement.
Use “ANTI-TWOBLOCK” disable switch when erecting and
stowing jib and when stowing hook block. While the switch is
pushed, the hoist does not stop, even when overwind condition
occurs.
When lifting a load by using jib (aux.winch) and boom (main
winch) simultaneously, do the following

：

• Enter the operation status as jib operation, not as boom

operation.

• Before starting operation, make sure that mass of load is within

rated lifting capacity for jib.

Before telescoping the boom, set the telescoping mode selector
switch to mode 1 or mode 2 with the boom fully retracted. A
change of the telescoping mode is not permissible when the
boom has been partially or fully extended.
Traveling on road in a special steering mode (four-wheel
steering,four-wheel sideways steering, etc.) is very
dangerous,and must be strictly avoided. Drive the machine in
two-wheel steering mode only. Special steering modes should
only be used for low speed travel within work sites.
Crane operation is prohibited without full counterweight 11.2 ton
mounted. Outriggers shall be extended 7.3 m spread when
mounting or dismounting removable counterweight.

DEFINITIONS

Load Radius

：

Horizontal distance from a projection of the axis of

rotation to supporting surface before loading to the center of the
vertical hoist line or tackle with load applied.
Loaded Boom Angle

：

The angle between the boom base section

and the horizontal, after lifting the rated lifting capacity at the
load radius.
Working Area

：

Area measured in a circular arc about the

centerline of rotation.
Freely Suspended Load

：
