1)Engine
■
Diesel engine with r ated power of 242kw (324hp)/2100rpm
and rated torque output 1424N·m/1500rpm.
■
Emission standard: Tier I II .
2)Electrical Control System
■
Advanced central co ntrol unit, load moment indicator,
display, sensor and closed-circuit monitoring system are
adopted.
■
Reliability: Advanced main electrical devices are
adopted to ensure the stabl e operation in the cold,
high temperature, plateau an d large sand storm harsh
environment.
■
Security: Elect rical design fully compli es with the CE
standard; the multi- level safety limit control is adopted
and all safety signal indi cators are complete.
■
Comfortable ness: The electrical paramete rs of all points
can be seen through the c ombination instruments in the
cab, to monitor all operati ng parameter and working state
in real time.
■
Advancement: The vehicl e electrical system adopts
the CAN bus system; the load power lim it load
control is adopted, wit h the calibration of redundant
communications and with the optional GPS.
3)Hydraulic System
■
The hydraulic system includes: Mai n valve hydraulic
system, main lifting hydraulic st ructure, boom luffing
hydraulic structure, jib luffing hydraulic structure, and
auxiliary hydraulic structure. .
■
Features: The main system is of open cir cuit, widely
adopting the electronic proportional control components.
The system adopts the load sen sitive LUDV system,
which can achieve the f low distribution irrelevant wit h
load. The hydraulic propor tional pilot control is adopted,
which is character ized by the sensitive operation and
good micro- mobility.
■
The system pressure is 32M Pa.
4)Main and Auxiliary Hoisting Devices
■
The bo om and jib winch mech anisms can be driven
separately, which is characte rized by the compact
structure, easy installa tion, and low wear. The
maintenance-fr ee built-in wet brake can ensure the
safety of winch.
■
The displacement of vari able hydraulic motor of lifting
mechanism can be automatically adjusted according
to the load, to achieve the maxi mum winch speed.
■
The high-quali ty anti-rotation wire rop e is adopted, to
ensure the high lifti ng safety and long life.
■
The pouch socket with swag ed sleeve is adopted to
ensure the convenient and quic k dismounting of wire
rope.
SUPERSTRUCTURE
NO.3 Boom luffing device
Outermost working layer rope speed 0~121m/m in
Diameter of wire rop e 28mm
Length of boom luffing wire ro pe 310m
Rated single line pull 17t
5)Boom Luffing Device
The boom luffing drum is equipped w ith the ratchet pawl
locking device, to ensur e the parking safety of boom
under non-working state.
NO.4 Jib luffing device
Outermost working layer rope speed 0~72m/min
Diameter of wire rop e 20mm
Length of jib luffing wire rope 410m
Rated single line pull 8t
6)Jib luffing Device
The ji b luffing drum is equipped wit h the r atchet pawl
locking device, to ensur e the parkin g safety of jib under
non-working st ate.
7)Swing Mechanism
■
It adopts the three- row roller slewing ring and is driven
by the large-displacement single motor reducer, with
the slewing speed of 0 -1.1r/min; it has the median
free s lipping function, with 36 0° rotation provided.
When the handle is at middl e position and there is no
slewing speed, the brake is at t he closed position and
the slewing is at the lock ing state through the locking
device. If the traveling or tr ansportation is done with
load, the upper rotar y impact should be prevented.
8)Counterweight
■
Carbody counter weight: 2; total weight: 30t (15t × 2)
■
Rear c ounterweight: 6t counterweight block, with a
total of 14; a counter weight tray of 16t, with a total of
100t.
9)Cab
■
The full-enc losed and wide-vision ca b having a
smooth shape and the Sany uni que style is adopted,
with the tempered glas s equipped at front and sides.
The GE structural s heet material is adopted at the
top, which is character ized by a good transparency,
high strength and high wear r esistance; the indoor
noise is low (less than 8 5dB). Air-conditioning, control
devices, instrumentation, fire alarms and closed circuit
monitoring system are installed indoors, in accordance
with the ergonomic design.
■
The cab can pitching 25 d egrees upwards, expanding
the vision of driver’s operation, improving the
operational safety, with the transport width reduced
due to its rotatable characteristics.
10)Control Operation
■
The track traveling oper ation can be controlled
through the handle or the t raveling pedal, having the
control automatic ally forward direction fun ction. With
the function of automat ic change of the direction of
steering, no matter th e superstructure rotates to no
matter the superstr ucture rotates to any direction,
the forward direc tion refers to the operator’s for ward
direction.
■
The boo m winch, jib winch, luf fing and rotar y actions
can be controlled by swi tching the handle function;.
■
There are all operatio n buttons and control switches
as well as the air conditio ning control panel on the left
and right armrest box, to ac hieve the different control
function.
11)Alar m Display
All alarm information, including the wind speed, water
temperature, oil temperature, oil level, oil pressure,
working hours time an d engine rotation errors, can be
shown on the display in the c ab, while giving the audible
and visual alarm.
