SPECIFICATION/CHASSIS

TECHNICAL PARAMETER

CounterweightMounted on the turntable through connecting

bolts.

Cab Fabricated from corrosion-resistant steel, huge-

arc integrated front window, convenient and easy

operation.

Main boomhuge-arc hexagonal cross section, telescopic

mechanism assisted by two cylinders and sheaves for

safety and high effection.

Main winch

High pressure automatic variable displacement

hydraulic motor with planetary gear type speed

reducer, spring-loaded constant-close brake set in

lifting and rising reducer.

Elevation

Deadweight dropping amplitude is controlled by

amplitude balance valve.

Slew

Slewing motor and reducer, max. slewing speed 2.3r/

min.

Aux. winch

High 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 Triple gear type main pump, the first pump activates

the actions for main and auxiliary winch, the second

pump controls extension , retraction, luffing, and the

third pump provides power for slewing and outriggers

of carrier.

Safety devicesLED touch monitor indicates important parameters:

torque parameter, hood load, rated load, boom length,

angle, lifting height etc., load chart and working data

setup integrated with functions of safety limitation.
