SPECIFICATION/CHASSIS

TECHNICAL PARAMETER

Counterweight4.5t, mounted on the turntable through

connecting bolts.

Operator’s cab Equipped with huge round arc integrated front window,

huge colorful display, clear and accurate, main control

instrumentation and working display system flexibly

combined for easy operation. Comprehensive safety

system and trouble-shooting and alarming system.

BoomBase boom and 4 section telescopic boom, hexagonal

cross sections.

Main winch

High-pressure automatic variable displacement

hydraulic motor drive block through planetary reducer;

spring-loading constant-close brake set in lifting and

rising reducer.

Luff Deadweight-dependent balanced valve control

elevation.

Slew unit Rotary motor drives rotary reduction gear, turntable

slews with center point. Rotary cushion valve and one-

way throttle with accumulator guarantee stable and

safe of starting and stopping of slewing. Max. slewing

speed≥2.5r/min.

Aux. winch

High-pressure automatic variable displacement

hydraulic motor drives block through planetary

reducer; spring-loading constant-close brake set in

lifting and rising reducer.

SPECIFICATIONSUPERSTRUCTURE

Hydraulic system Main oil pump is trilink gear pump, main valve drives

by control-pressure of pilot handle; first pump for all

the movement excluding slewing, second pump for

slewing of outriggers of chassis and of superstructure,

third pump supplies oil for pilot and control-pressure

as control pump.

Safety devicesWide colorful touch screen displays moment

proportion, hook load, rated load, boom length, angle,

slewing radius and so on; alarm signed, easy for

trouble-shooting, load chart and working parameter

set in system as black box.
