SUPERSTRUCTURE

1） Engine
Diesel engine with rated power of 242kw (324hp)/2100rpm
■
and rated torque output 1424N·m/1500rpm.
Emission standard: Tier III .
■
2） Electrical Control System
Advanced central control unit, load moment indicator,
■
display, sensor and closed-circuit monitoring system are
adopted.
Reliability: Advanced main electrical devices are
■
adopted to ensure the stable operation in the cold,
high temperature, plateau and large sand storm harsh
environment.
Security: Electrical design fully complies with the CE
■
standard; the multi-level safety limit control is adopted
and all safety signal indicators are complete.
Comfortableness: The electrical parameters of all points
■
can be seen through the combination instruments in the
cab, to monitor all operating parameter and working state
in real time.
Advancement: The vehicle electrical system adopts
■
the CAN bus system; the load power limit load
control is adopted, with the calibration of redundant
communications and with the optional GPS.
3） Hydraulic System
The hydraulic system includes: Main valve hydraulic
■
system, main lifting hydraulic structure, boom luffing
hydraulic structure, jib luffing hydraulic structure, and
auxiliary hydraulic structure. .
Features: The main system is of open circuit, widely
■
adopting the electronic proportional control components.
The system adopts the load sensitive LUDV system,
which can achieve the flow distribution irrelevant with
load. The hydraulic proportional pilot control is adopted,
which is characterized by the sensitive operation and
good micro-mobility.
The system pressure is 32MPa.

4） Main and Auxiliary Hoisting Devices
The boom and jib winch mechanisms can be driven
■
separately, which is characterized by the compact
str ucture, easy installation, and low wear. The
maintenance-free built-in wet brake can ensure the
safety of winch.
The displacement of variable hydraulic motor of lifting
■
mechanism can be automatically adjusted according
to the load, to achieve the maximum winch speed.
The high-quality anti-rotation wire rope is adopted, to
■
ensure the high lifting safety and long life.
The pouch socket with swaged sleeve is adopted to
■
ensure the convenient and quick dismounting of wire
rope.
NO.1 Main lifting device
Outermost working layer rope speed 0~110 m/min
Diameter of wire rope 28 mm
Length of wire rope of boom winch 480m
Rated single line pull 17t
NO.2 Auxiliary lifting device
Outermost working layer rope speed 0~110 m/min
Diameter of wire rope 28 mm
Length of wire rope of boom winch 390m
Rated single line pull 17t
5） Boom Luffing Device
The boom luffing drum is equipped with the ratchet pawl
locking device, to ensure the parking safety of boom
under non-working state.
NO.3 Boom luffing device
Outermost working layer rope speed 0~121m/min
Diameter of wire rope 28mm
Length of boom luffing wire rope 310m
Rated single line pull 17t
6） Jib luffing Device
The jib luffing drum is equipped with the ratchet pawl
locking device, to ensure the parking safety of jib under
non-working state.
NO.4 Jib luffing device
Outermost working layer rope speed 0~72m/min
Diameter of wire rope 20mm
Length of jib luffing wire rope 410m
Rated single line pull 8t
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 slipping function, with 360° rotation provided.
When the handle is at middle position and there is no
slewing speed, the brake is at the closed position and
the slewing is at the locking state through the locking
device. If the traveling or transportation is done with
load, the upper rotary impact should be prevented.
8） Counterweight
Carbody counterweight: 2; total weight: 30t (15t × 2)
■
Rear counterweight: 6t counterweight block, with a
■
total of 14; a counterweight tray of 16t, with a total of
100t.
9） Cab
The full- enclosed and wide -vision cab having a
■
smooth shape and the Sany unique style is adopted,
with the tempered glass equipped at front and sides.
The GE structural sheet material is adopted at the
top, which is characterized by a good transparency,
high strength and high wear resistance; the indoor
noise is low (less than 85dB). 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 degrees upwards, expanding
■
the vision of dr iver' s operation, improving the
operational safety, with the transport width reduced
due to its rotatable characteristics.
10） Control Operation
The track traveling operation can be controlled
■
through the handle or the traveling pedal, having the
control automatically forward direction function. With
the function of automatic change of the direction of
steering, no matter the superstructure rotates to no
matter the superstructure rotates to any direction,
the forward direction refers to the operator' s forward
direction.
The boom winch, jib winch, luffing and rotary actions
■
can be controlled by switching the handle function;.
There are all operation buttons and control switches
■
as well as the air conditioning control panel on the left
and right armrest box, to achieve the different control
function.
11） Alarm Display
All alarm information, including the wind speed, water
temperature, oil temperature, oil level, oil pressure,
working hours time and engine rotation errors, can be
shown on the display in the cab, while giving the audible
and visual alarm.
