B.08 Theory chart of hydraulic system
B.09 Selecting of parts line of rope
Note！When the truck crane working , the selecting of parts line of rope must obey the
fundamental as follows:
1、The hoisting rope select four parts line when truck crane shipped ex-works. Because in
that state, can satisfy the working condition above 4.85 metres and it can advance
efficiency.
2、When the length of boom under 4.85 metres and the lifting weight hyper 7.5 tonnage ,the
rope must be changed to six parts line.
six parts line four parts line
C.00 Safety rules & device
C.01 Working condition
· Do not working under the power lines Unless keep the min distance of 5 m from it and
other provisions apply in the area in which you are operating the crane .
·the ground of working must be hard and level ,the grade less than 1:20 and the surface not
sink
C.02 Environment condition
Before using the crane, always assess the ambient conditions (wind, temperature, risk of
lighting) in order to work in safety.

徐州徐工随车起重机有限公司
- 13 -
·don’t operate crane when it is raining or lighting or wind speed exceed 13.8m/s (grade 6).
·environment temperature: -25°C- +40°C
C.03 Requirement for rope use
The illustration is intended to the right way when use rope to fix weight. The Max angle
A should be less than 1200, or the rope may be broken by force. If the angle A is too small, the
system working pressure may be too high when lifting load.
C.04 General description of safety rules.
·The operator must have a thorough understanding of the crane and must keep it in efficient
condition. If in doubt, refer to the instruction manual.
·Only authorized personnel may use and operate the crane.
·Do not leave the control station with the load raised or the machine in operation.
· make sure unauthorized persons out of the crane’s operating area.
·do not operate 2 devices simultaneously with the load raised.
•Warning ！
Do not operate the machine in the area marked ‘ not allowed work area ’in the
below figure, be sure to not operate the machine in the area marked‘bad stability work
area ’in the below figure.

The crane must be stabilized on firm ground. When working on soft or yielding ground you
must increase the load-bearing area by placing a stabilizer support plate between the base of the
stabilizer leg and the ground in order to distribute the load sufficiently. Do not operate the crane
close to ditches or on soft, yielding ground.
danger!!
•You must know, at least approximately, the weight of the load you intend to lift, and the load not
exceed the indicated value in figure.
•Use the controls on the same side as the load so as to ensure maximum visibility.

徐州徐工随车起重机有限公司

•do not stand under the load.
• do not hoist weight at a angle.
·don’t push the load or push the load aslant, don’t lifting the load imbedded in the ground or
congealed on ground.
·make sure no barrier in the way of load when it is leave the ground exactly
danger!!
·When the weight is equal to (or less than) the 2/3 of the max capacity at the working range,
you can retract the telescoping boom but not extension .·When the weight is equal to (less than)
the 2/3 of the max capacity at the max working range, you can extend or retract the boom
·Use ropes to guide the load at a distance and prevent it from swinging.
OK
•Do not use the crane to lift persons.

danger!!
•Before starting a lifting operation, always check the condition of the lifting tackle(ropes,
hooks, chains or straps).the goods should be fastened for safety.

C.05 Safety devices
C.05.1 Lock device on fixed legs
This machines is fitted with a locks installed on the fixed leg on the right and left side of the
crane.
lock the locking device when the truck is working or transporting, slewing the locking
device 180°and pull the active leg out .
In the same way ,slewing it back 180°and retract the active leg ,set the locking lever inset the
hole of active leg automatically .
C.05.2 Valves on hydraulic cylinders
These values hold the load in the position reached in the event of failure of the power circuit
hoses, and in the absence of motive power caused by accidental operation of the control levers.
These valves are fitted on：
1. telescopic cylinder 2. derricking cylinder 3. vertical leg cylinder
C.05.3 Anti-rotation device
Several warning labels are affixed to your machine. Be sure to refer to the warning
labels on the pin shaft bush side of base when operating your machine; be sure to pull out
anti-rotation pin shaft before operation of the machine, and insert it in the pin shaft hole of
base after work is finished.
In addition,keep pin shaft locked when travelling of the machine.

C.06 Forecast risk and unforecast risk area
forecast risk：signifies that element of risk which it was not possible to eliminate at the
design stage and which is not protected by the safety devices.
Unforecast risk area：refers to any potentially hazardous point inside or close to the
machine or in the crane’s operating range.
The following may be sources of risk：
•The incorrect positioning of the machine in its work configuration in which dose not offer
an easy escape route for the operator.
•Electrocution due to contact with overhead power lines or lightning.
·asphyxia was caused by close the exhaust long time.
·locking leg cylinder incorrectly(extend or retract fully)

The operator must therefore be fully aware of the safety rules and devices and must also be
familiar with the use of the operating controls and load harnessing techniques.
Responsibilities:
The operator is directly responsible for the operation and correct functioning of the crane,
for its maintenance, for the load being handled and for every action he performs in the context of
the duties referred to above.
D.03 Control stations
The two illustrations on this page show the positions(right and left side of the machine)
which the operator must occupy when operating the crane.
CAUTION：Remember that you must ALWAYS use the controls on the same side as the
load, adopting a natural and well-balances stance.
E.00 Control devices
E.01 Oil level indicator
The crane’s oil tank is fitted with an optical level indicator for checking the amount of oil
in the tank.
E.02 Crane operation controls
There is a rotary valve control lever 5 on the stabilizer controls
Shift the lever 5 to the position A to control the stabilizer (including lever 1,2,3 and 4)
