SPECIFICATION/CHASSIS
TECHNICAL PARAMETER
Counterweight3.2t basic counterweight fixed on the swing
table by bolts.
Operator’s cab Spacious comfortable crane cab, large arc
windscreen, broad vision. Operation parameters
indicated, graphic symbols displayed for diagnosis,
alarm function.
Main boom4 section, hexagonal profile.
Main winchHigh pressure automatic variable displacement
hydraulic motor with planetary gear type speed
reducer, spring-loaded constant-close brake set in
lifting and rising reducer.
SPECIFICATIONSUPERSTRUCTURE
Hydraulic system CY: Triple gear type main pump, and the upper multi-
way valve controlled by pilot joysticks to ensure the
driving work. The 1st pump activates all actions except
the slewing; the 2nd pump is functions for outrigger and
swing table, and the 3rd pump provides power for fluid
and pressure control.
CS: Triple gear type main pump, and the upper multi-
way valve is driven by a hand lever, the 1st and 2nd pump
activates for all actions except slewing and 3rd pump
functions of outriggers and swing table.
Elevation
Deadweight dropping amplitude is controlled by
amplitude balance valve.
Slew
Slewing motor with rotary speed reducer, rotary buffer
valve and single direction throttle valve equipped,
reliable and safe start/stop actions can be ensured.
Max. slewing speed ≥2.5r/min.
Aux. winch
High pressure automatic variable displacement
hydraulic motor with planetary gear type speed
reducer, spring-loaded constant-close brake are set
in lifting and rising reducer.

Safety devicesLED touch monitor indicates important parameters:
torque percentage, hook load, rated load, extension
length of main boom, angle, slewing radius etc., and
graphic symbol display for diagnosis, load chart
and working parameter setup integrated. It can also
function as black box.
