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.
