7.5t Digging Hydraulic Crawler Construction Machinery Small Excavator

Small excavator is designed with high engine output power, fast speed and high fuel efficiency, suitable for demanding jobsites.

Superior Performance

Powerful Engine

Four-cylinder engine and four stroke direct-injection provides a stronger power for the excavator.

Auto Deceleration System

Auto deceleration reduces fuel consumption by 5-10%. The engine speed drops automatically to idle level and maintains the idling state when the operation stops for 3.5 seconds.

Faster Operating Speed

A quick return line is added to the arm oil cylinder circuit, considerably improving the operating efficiency at low energy consumption. Main pump delivery increases from 149 liters to l68 liters. Faster speed is achieved in separate operation.

Innovative Dozer Blade 

Equipped with an innovative dozer blade that has an increased magnitude of moving up and down, 7.28 ton excavator is very suitable for complex operating conditions, such as road construction and burying pipelines or cables.

Environmentally Friendly

Keep exhaust emission in line with EPA interim Tier2/EU Stage B Emission Standards, the engine is environmentally friendly.

Safe and Comfortable Operating Environment

Innovative Large Cab

The newly-designed cab with much room and larger windows provides you with a wider view.

Air-conditioner with Multiple Air Outlets 

High quality air conditioner provides better cooling effect and creates a more comfortable operating environment by automatically regulating the temperature and humidity inside the cab.

Clean, Quiet and Well-sealed Cab

Equipped with excellent sealing, the cab is free from dust, rain, and noise that effectively reduce the fatigue of operator.

Multi-functional Controller 

Multi-functional controller ensures constantly optimum condition of the system. When the joysticks are not operated for 3.5 seconds, the engine will lower the speed to reduce fuel consumption. When there is something wrong with the engine or hydraulic system, the monitor will report the fault information to warn you. 

Higher Reliability and Durability

Reinforced Boom

The side plates are thicker than before and the ear plates are redesigned to reduce stress at the bending. The boom has stood the durability test and field (soil and rock mixture) digging test.

Reinforced Bucket

The shape of bucket has been redesigned. The bucket boom uses quality anti-wear plates with its thickness going up by 33 percent that significantly enhances the durability of bucket. There is no damage to the bucket during tests.

High-strength Track Frame

The optimized dozer blade cylinder support is welded to the upper and lower plates in a gearing manner in order to have better strength and rigidity.
