21 ton excavator is most suitable for road construction, building construction and evenly for mining construction. This excavator is standard equipped with 113kw ISUZU engine, Kawasaki hydraulic pump, air conditioned cabin and 600mm steel track. Accessories as hydraulic quick change coupler, hydraulic breaker, grapple and hydraulic shear are all optional. Smooth operation and high efficiency make the excavator more competitive.
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
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.
