20. How to read the capacity charts
( 10
)
The lifting load with which you can extend or retracted the boom during searcher hook operation may become
smaller then the lifting capacity depending on the conditions such as the oil pressure, boom angle, lubricating state to
the boom, etc.
(11) In whatever working conditions the corresponding boom critical angle is shown in the chart. The crane can tip over if
the boom is lowered below the critical angle even if unloaded. Therefore, never lower the boom below these angles.
(12) The standard parts of line for each boom length are as indicated in the chart. If you work with a non-standard
number of parts of line, do not exceed 28.4 kN
(2.9 tf)
per wire rope respectively.
(13) High-speed winch operation should only be performed to allow descent of the hook alone. Avoid sudden lever
operation.
(14) Crane operation is permissible up to a wind speed of 10m/s. Even in relatively light wind conditions, extra care
should be taken when handling loads presenting large wind catching areas.
(15) The boom guard must be removed during crane operation.
(16)
If you work with a load in excess of the lifting capacity or use incorrect working procedures, you are risking
damaging the crane or tipping it over. In such cases, the crane will not be guaranteed.
20-3-2 Precautions when the outriggers are not used
(T218351-038-0E)
(1) The lifting capacity chart indicates the maximum load the crane can lift when its body is level on firm level ground
with all tires inflated to the rated pressure and suspension cylinder completely retracted. The values in the chart
include the mass of the main hook and slings.
Within the chart the figures in the area bordered with a thick line are based on structural limitations while other
figures are determined by stability limitations.
[
Rated tire pressure: 900kPa
(
9.0 kgf/cm
2 )]
(2) The working radii are the actual values allowing for boom deflection. Therefore you must always operate the crane
on the basis of the working radius.
(3) The lifting capacity differs between the front area capacity and the full range capacity. When slewing from the
front to the side, take care that the crane could not be over loaded.

(4) The lifting capacity of the rooster sheave is the lifting capacity of the boom minus the mass of all attached hook,
slings etc. to the boom, with an upper limit of 3,200kg.
[The hook for use with the rooster sheave is the 3.2ton hook (
mass: 60kg
) with one part of line.]
(5) Work within the capacity indicated in the lifting capacity chart.
(6) For stationary crane-on-rubber operation, the parking brake and brake lock device must be engaged.
(7) For pick and carry operation, the high/low speed switch must be switched to "ON"
(low range) and the shift lever
set to speed 1.
(8) For pick and carry operation, lower the load to just above the ground and keep your speed strictly below 2km/h to
avoid swinging the load.
Take particular care to avoid sharp turns, sudden starts and stops.
(9) Never operate the crane during pick and carry operation. The slewing brake must be applied.
