Earthmoving Machinery 88-8 Excavator |Earthmoving Machinery Excavator Crawler Excavator

Engine
Theoriginal Cummins B3.3 engine with unique design, it has 40% less parts andcomponents comparing with other similar engine of this category so the failurerate greatly reduced. The daily maintenance is easy because no need of anyspecial tools.
The engine is lighter, Euro II emission meets theenvironmental protection requirements, and yet powerful.
The unique radiationsystem enable an uniform cooling distribution. Even in hot summer condition itcan maintain normal engine working temperature.
It adopts thedirect-fuel-injection system, forced lubricating with? full-flow oil filtrationand the multistage dry air filter.
The automatic dust discharge valve and airfilter jam indicator, make maintenance simpler and extend air filter servicetime.
Hydraulic system:
The hydraulic components (pump,valve, motor, pilot valves etc) are world well know brands. The patentedJapanese IB system with
perfect combination of release circuit and loadsensing, reduce the
flow loss of the pressure compensation at the oil inlet,so to eliminate heat generating and increase the system efficiency; at the sametime it makes the composite movements more gentle so to improve operationperformance of the excavator, reduce the labor intensity of the operator.
Thecomposite pressure comparing compensation system makes all movements moresmooth; and increase machine lifetime.
The main and secondary oil circuitsrealizes the flow regeneration
based on the single-pump large flow, tofurther improve the moving speed of swing boom and arm, so the operationefficiency is doubled with obvious energy saving.
The optimized design of thecomposite movement, and simplified structure has changed the traditionalhigh-pressure signal feedback, first time adopts the low pressure and automaticpower compensation function, which make the whole performance stable andeffective, the priority function is easy to achieve, the operation andmaintenance is simplified greatly;
Japanese Toshiba swing motor has compactstructure, large swing torque, rapid swing speed, reliable operation with smoothbrake.
Comfort
The operator cabin is ergonomics designed, with spaciousinner space, wide vision and attractive appearance. It is equipped withhigh-back air suspension seat, the height, leg room, and back angle can beadjusted individually to suite different operators for the most comfortableworking posture to reduce the fatigue; the cab also equipped with heater and airconditioner so to offer a comfortable operation environment all year round.
Locking handle make the machine safer
When the locking handle is set atthe position Lock”, all the operations including travel, bulldozer, workingdevice and swing will be locked.
Compact structure and small swing radius
The swing radius is smaller than other models of the same kind, which canensure higher working efficiency even in the restricted working area.
Highlyintegrated electrical- control units
All the parts of the electrical systemare integrated in one controller, which makes the outer line simple and easy tobe checked and maintained.
Electrical monitor and check function to be
clear at a glance
The instrument penal uses multi-functional liquidcrystal display(LED) in bi-lingual displays (Chinese-English), which is strikingand artistic. It concentrically displays the working status of the engine (watertemperature, pressure of engine oil etc.), working status of the hydraulicsystem, electrical signal, working time etc.
The overall failure alarm andrecord function make the operator aware of the status of the excavatorcomprehensively just by staying in the cabin. It can not only guarantee the safeoperation of the machine, but also maintain can be carried out rapidly accordingto the alarm record should a problem occurred in the system.
The digitaldisplay monitor system control the working status of machine in real time.
Easy maintenance
All the maintenance points are easily accessible byjust opening the? machine hoods.
Advanced process technology
Allconnecting surfaces of bucket arm and boom have been treated withwear-resistance coatings so to greatly increase the wear-resisting property.
