Product Description

 

Dynanic System

 

The original imported Yangma engine specially provided can ensure the reliability of the machine under severe working conditions.

Advantages of Yangma engine:

• Micro excavation is widely used and highly recognized by customers.

• Durable, fuel saving, cheap accessories, convenient maintenance, the first choice for excavators

• Standard 4-inch large size, high-precision air filter, two-stage filtering, with filtering accuracy of more than 99.9%; Equipped with air filter alarm device for real-time reminder; Large capacity ash design, long service life, low maintenance cost.

• High precision oil-water separator with filter screen is adopted, which can effectively filter impurities in the fuel while separating water and improve the service life of the engine.

• Precision of fine filtration 1μm. It can filter the tiny impurities invisible to the naked eye of the fuel to ensure the safe use of the engine.

The parallel super large heat dissipation system is adopted, which has strong heat dissipation capacity and ensures the service life of the engine.

• High power starting motor and generator are used for better adaptability.

 

Hydraulic System

 

• The special main pump and valve, rotary motor and traveling motor ensure the high reliability of the hydraulic system.

• The original SLSS hydraulic system is used to achieve the perfect match between the engine and the main pump, which can maximize the use of the output power of the engine and improve the operating efficiency.

• SLSS hydraulic system, which is leading in the industry, can realize accurate flow control according to the change of load, and has excellent micro operation performance, just like human hands.

• Full hydraulic control: all actions are controlled by pilot hydraulic control, no empty stroke, good micro control, safe and accurate, more smooth action, and lower fuel consumption.

 

Enhanced Structure

 

Boom stick

First class core configuration First class core configuration

• The boom stick is sturdy and durable, and its performance is superior to the industry level.

• Add stop valve for auxiliary pipeline, and replace accessories without oil leakage.

• Standard equipped with extended stick, with a wider working range.

Slewing bearing

Enlarge reinforced slewing ring, durable and more reliable.

Reinforced frame

• Reinforced working device and frame, based on the ANSYS platform, optimize the structure, reduce stress concentration, and prolong the average life by 30%.

• TOPS/ROPS analysis of the canopy, safe and reliable.

Flexible Structure

Deflectable Device

The range of the deflectable working device is: left deviation 595mm, right deviation 350mm, both sides can easily dig to the outer edge of the crawler, and can work in space-limited positions such as walls and corners.

Flexible control
Retractable walking frame and boom side shift make work more flexible and adapt to more scene, small and exquisite, easy to transport.

Flexible and convenient retractable walking frame

• The width adjustment range of the retractable walking frame is 980mm~1350mm, which improves the stability of the whole machine.

• The interchange of steel track and rubber track can be realized to meet the needs of various working conditions.

Rotatable bulldozer

The rotating cartridge bulldozer can ensure the passability, allowing the excavator to easily pass through the working space of less than 1m and improving the working efficiency.

 

High Value Preservation

Second-hand better value

It is a star product of the main mini -excavator of major international brands of heavy machinery, and the excavator has been sold for many years.
The number is leading other brands of other tonnage, the market share is high, and the value preservation rate of the second -hand market is very high.

Multipurpose&Multi Accessory

Two-way auxiliary pipeline and globe valve are standard equipped to meet the needs of different auxiliary equipment such as crushing, hydraulic shears, and grab buckets.

A: Broken pipeline	B: soil improvement	C: Scrap Screening	D: Wide bucket construction
E: narrow bucket construction	F: trench excavation	G: Loading and Slope Construction	H: Hard soil excavation

Comfortable Driving Experience

 

Comfortable Space
• The seat installation position is adjustable front and rear, the seat cushion is large, the backrest is raised, and the riding comfort is better, which can meet the driving requirements of drivers of different sizes.
• Cast aluminum foot pedal, beautiful and elegant, wide and comfortable foot pedal space, easy to operate.
• Adjustable arm rests can avoid long-term operation fatigue.
• Added cup holder and glove box for easy storage.
• Add 12V power supply to facilitate your life.

Safety Facilities
• The operating handle is disabled when the hydraulic pilot lock lever is in the locked position.
• The main power switch, seat belts, various safety signs, etc. are readily available.
• Optional walking alarm light, fire extinguisher, emergency stop switch.

 

Easy Daily Care

• The daily maintenance is concentrated at the rear of the machine, and the air filter, oil filter, fuel filter, oil-water separator, fuel gauge, auxiliary water tank, oil filler, water tank filler, and water tank exhaust can be accessed by opening the rear hood Valve, air filter alarm, fuse box, easy maintenance and good accessibility.

• Clamps are attached to the counterweight to accommodate the grease gun.
• A tool box is provided behind the seat for easy carrying of maintenance tools.
• Removable radiator dust filter for easier cleaning.
