Front axle is connected with frame rigidly; swing, rigidly lockable
hydraulic suspension is used for rear axle. The shock absorption
function of rear suspension may be performed through the swing
mechanism and suspension cylinder when driving on roads,
consequently road shock is buffered and travel smoothness is
improved; the rear suspension cylinder may be locked to rigid state
so as to meet the requirement for travel with a load suspended.
Full hydraulic electro-proportional multi-mode steering: front axle
independent steering, small turning radius steering, crab walk
steering and rear axle independent steering are available.
Switch over of wheel turning direction: when the vehicle is driving
while the turntable is turned over 90°, the control system will
send a signal through the position sensor fitted on the turntable
for controlling the hydraulic change valve between the steering
wheel and the change cylinder of front axle. And then the vehicle
drives in reverse direction, and the rotating direction of the
steering wheel is the same as that for forward driving, which fits
operator’s operating habit.
Service brake: double-circuit full-hydraulic disc brake, acting on
all wheels; when the pressure in braking system is too low,
automatically braking function works.
Four-point supported outriggers, electrical control and hydraulic
operating, one-stage telescoping manner is used for outrigger
beams.
The main boom includes one base boom and four-telescoping section,
is made of high strength structural steel, with quadrilateral cross
section. Anti-torsion design is adopted. Good stability in the
lifting operation is available. Double-cylinder plus ropes
telescoping mechanism is for synchronous plus sequential
telescoping. Eight pulleys on boom head are standard.
Hirschmann Load moment limiter system with advanced
micro-processing technology employed, has features of less power
consumption, powerful function and high sensitivity, and is easy to
operate. LCD with large screen will show the lifting operation
data, such as moment percentage, actual lifting capacity, rated
lifting capacity, working radius, boom length, boom angle, max.
lifting height, working condition code, parts of line, limited
angle, information code, etc. by means of Chinese and graphical
symbol. It has complete forewarning and overloading cutout
function, as well as overloading memory (black box) and fault
self-diagnosis function.
