21 Ton Hydraulic Excavator

FEATURES & BENEFITS

ORIGINAL ISUZU ENGINE

Strong power output and digging force make excavators work more efficiently.

Automatic idle speed prevents unnecessary fuel consumption.

Control equipment hydraulic loss and engine fuel loss through central integrated control.

Use high efficient matching technology between engine and hydraulic system.

Use a specially designed for construction machinery high pressure fuel injection system

to improve engine durability.


 



ADVANCED HYDRAULIC SYSTEM

Use KAWASAKI large displacement main pump and Parker main valve.

There are lots of advantages such as good complex operation, precise action,

easy and efficient operation, etc.

Water cooler and oil cooler make better cooling effect, and prevent overheating.

Main parts in hydraulic and electrical system are international advance brand.



 



COMFORTABLE AND SAFETY

Low noise engine and pressure seal, absorption of vibration cabin ensures good

noise reduction capability.

Air conditioned cabin, it is easy to set the cabin temperature and maintain constant

cabin temperature through quick button. Defrost function makes sure the front window clear.

Floated seat with vibration-absorptive function and safety belt, position can be adjustable.

Fixed with strong adhesive force anti-slip plate.

Clapboard of engine room: thermal shield, noise reduction, to prevent oil splashed on the

high temperature position of engine by accident.

Thermal baffle: to prevent the hand touch the high temperature position or get hurt by the

fan when checking the engine.

Special cabin: model designs, structure design of large cross section ensure the durability

of the cabin. Strengthened frame enable the cabin greatly enhance the shock resistance.

Safety locking bar can lock the equipment hydraulic to prevent mis-operation.

 



MONITOR WITH ECU

Color LCD display in English and Chinese.

The controller monitoring the fuel level, coolant temperature and battery charge, etc.

Any abnormal situation will be show on the screen and alarm.

The controller will notify to replace the oil and filter when the replace cycle has come.

Volume of work priority and fuel saving priority function.

H mode: heavy load, but work fast

S mode: middle load, considering both operating and fuel consumption

L mode: light load, low fuel consumption priority

 



STRONG FRAMES

Use of 3D design and finite element analysis, achieve a reasonable

high strength structural.

The boom, digging arm and bucket all using strengthen intensity as standard

configuration, which can meet user’s demand of long term and high intensity construction.

Use high wear resistance steel plate for bucket.

Large cross-sectional design boom, all stressed part been strengthened, thus the

maximum avoid the stress concentration, improve service life.

Strengthened swing plate.
