20. How to read the capacity charts
20-3 Precautions on crane operation
(541A-0149-3E)
Familiarize yourself with the following points before you start to operate the crane. There is a safety sign of the lifting
capacity chart inside the cab on which the summary of these same points is also given. Always read them before you
start to operate the crane.
20-3-1 Precautions when the outriggers are used
(T218351-037-0E)
(1)
The lifting capacity chart indicates the maximum load which can be lifted by this crane provided it is level and
standing on firm level ground. The values in the chart include the mass of the main hook and slings for boom
operation, and auxiliary hook and slings for jib operation.
The values in the chart are values with the main and auxiliary hooks removed and main and auxiliary wire ropes
stowed for searcher hook operation.
[
20ton hook
(
mass: 150kg
), 3.2ton hook (
mass: 60kg
)]
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.
(2)
The working radii are the actual values allowing for boom and jib deflection. Therefore you must always operate
the crane on the basis of the working radius.
(3)
The jib working radii are based on the jib mounted on the end of the 19.6m or 28.0m boom. If the boom is at any
other length (
more than 19.6m and less than 28.0m
)
, use the boom angle for the 28.0m boom alone as the criterion.
If the boom length is less than 19.6m, use the boom angle for the 19.6m boom alone as the criterion.
(4)
Do not operate the jib when the outriggers are completely retracted.
(5)
The lifting capacities for the over sides vary with the outriggers extension width. Therefore for each outriggers
extension condition you should work according the lifting capacity chart. Use the lifting capacity chart of
outriggers full extension for both front and rear areas lifting capacities.

(6)
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.]
(7)
If the boom length, boom angle, working radius and/or jib angle exceeds the rated value, use the lifting capacity
for the rated value or for the next one, whichever gives the smaller lifting capacity.
(8)
If you are working with the boom while the jib is rigged, subtract 1,500kg plus the mass of all attached hook,
slings, etc. to the boom from the each lifting capacity of the boom, with an upper limit of 10ton.
Do not use the rooster sheave in this situation. And do not operate the boom while the jib is rigged, when the
outriggers are completely retracted.
(9)
If you are working with the boom while the searcher hook is rigged, subtract 80 kg plus the mass of all attached
hook, slings, etc. to the boom from each lifting capacity of the boom.
