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.
Modications to the machine or use of optional equipment other
than that specied 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
Maintenance Manual supplied with the crane. If this manual is
missing,order a replacement through the distributor.
The operator and other personnel associated with this machine
shall fully acquaint themselves with the latest American National
Standards Institute (ANSI) safety standards for cranes.
SET UP
Rated lifting capacities on the chart are the maximum allowable
crane capacities and are based on the machine standing level on
rm 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 oats 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 have been tested to and meet minimum
requirements of SAE J1063-Cantilevered Boom Crane Structures
Method of Test.
Rated lifting capacities do not exceed 85% of the tipping load on
outriggers fully extended as determined by SAE J765-Crane
Stability Test Code.
Rated lifting capacities FOR partially extended outriggers are
determined from the formula, Rated Lifting Capacities=(Tipping
Load-0.1×Tip Reaction)/1.25.
Rated lifting capacities above thick lines in the chart are based
on crane strength and those below, on its stability. They are
based on actual load radius increased by boom deection.
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, ination of
tires, operating speeds, side loads, etc. Side pull on the boom or
jib is extremely dangerous.
Such action can damage the boom, jib or swing 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 9 m/s
(20 mph) to 12 m/s (27 mph); reduced by 70% when the wind speed is
12 m/s (27 mph) to 14 m/s (31 mph). If the wind speed is 14 m/s (31
mph) or over, stop operation. However, in the following conditions,
stop operation at wind speed of 12 m/s (27 mph): Boom length is 56.0
m (183.7') (all 100%), and boom angle is 55º or less. Boom length is
52.7 m (172.9') (all 92%), and boom angle is 45º or less.
During jib lift, stop operation if the wind speed is 9 m/s (20 mph) 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 7,200 kg (15,900 lbs.) for main
winch and auxiliary winch.
Check the actual number of parts of line with LOAD MOMENT
INDICATOR (AML-C) before operation. Maximum lifting capacity
is restricted by the number of parts of line of LOAD MOMENT
INDICATOR (AML-C). Limited capacity is as determined FROM
the formula, Single line pull for main winch 7,200 kg (15,900 lbs.)
x number of parts of line.
The boom angle before loading should be greater to account for
deection. For rated lifting capacities,the loaded boom angle and
the load radius is for reference only.
Maximum capacity without boom pin is shown in the chart.
Do not operate extension or retraction of the boom with loads.
For lifting capacity of 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 7,200 kg (15,900 lbs.) including main boom hook mass
attached to the boom.
When the base jib or top jib or both jibs are removed, set the jib
status switch to 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-TWO-BLOCK" 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.
For selected boom length or less with jib, rated lifting capacities
are determined by loaded boom angle only in the column headed
"selected boom + jib".
The boom extending operation and lowering operation are
prohibited during lifting a load with multiple line lift.
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 the mass of a load
is within the rated lifting capacity for the jib.
(The AML display indicates inaccurate working radius and
actual load values during multiple line lift.)
When lifting a load by using single top (aux.winch) and boom
(main winch) simultaneously, do the following:
• Enter the operation status as single top operation, not as
boom operation.
• Before starting operation, make sure that the mass of a load
is within the rated lifting capacity for the single top.
(The AML display indicates inaccurate working radius and
actual load values during multiple line lift.)
Crane operation is prohibited without full counterweight 10
metric ton (22,000 lbs.) installed. Outriggers shall be extended
7.3 m (23'11 3/8") spread when installing or removing 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: Load hanging free with no direct
external force applied except by the hoist line.
Side Load: Horizontal side force applied to the lifted load either
on the ground or in the air.
