1. High-efficiency Kawasaki hydraulic system: The overall performance of the hydraulic system is
reasonably matched with the output power of the engine, which significantly reduces energy loss.
2. High-reliability Cummins engine: Using the
well-proven Cummins 6LTAA8.9-C280-II engine, it has abundant power and good durability and is suitable for
fuel in general areas with high fuel economy. Reduce fuel consumption through advanced control technologies
in hydraulic and Cummins engine aspects.
3. High efficiency working performance: The potent power
output and Jingong's unique intelligent control system and intelligent power control technology ensure efficient
operation and reduce fuel consumption.
1). Intelligently senses the working intensity of the equipment in the actual working
conditions, automatically adjusts the engine speed and the torque of the main pump, and further reduces fuel
consumption while meeting the working efficiency.
2). Power mode (H), standard mode (S), and economic mode (L) can be freely selected
according to actual working conditions. At the same time, through automatic idle speed and intelligent control
of main pump flow and hydraulic system pressure, power loss is reduced, and low fuel consumption is
achieved.
4. Reliability:
The reliability of an item of the plant contributes to its overall lifetime operating
costs. JinGong uses computer-assisted design techniques, highly durable materials, and structures then test
these under extreme conditions.
The durability of materials and longevity of structures are our first priorities.
Strengthened boom
The shape of the boom has been optimized by finite elements design, allowing the loads
to be better distributed throughout the structure. This combined with increased material thickness means
improved durability and reliability by limiting element fatigue.
Arm assembly
In the arm assembly, greater strength has been gained by using cast elements and
reinforcement around the bosses to give it an increased lifetime.
X-chassis
The X-chassis frame section has been designed using finite elements and 3-dimensional
computer simulation, to ensure greater durability and optimum structural integrity. The swing gear is solid and
stable.
D-type frame
The D-type frame and chassis frame add strength and minimize distortion due to
shocks.
Bucket
Highly wear-resistant materials are used for the most susceptible elements such as the
blades, teeth, rear and lateral reinforcement plates, and corners of the bucket.
5. Luxury cab:
Adhering to Jingong's driver-centered design concept, with comfortable operation, wide
field of vision, and low noise. It has an air-conditioning system that meets the operation's needs and a
multi-functional LCD instrument panel to improve the comfort and convenience of the operation.
The main frame and boom are equipped with LED work headlights as standard:
significantly improving the driver's night work vision and improving night work efficiency and safety.
6. Maintainability:
Short maintenance operations at long intervals increase the availability of the
equipment on site. JinGong has developed the JGM938L with a view to high profitability for the user.
Access to the various radiators is very easy, making cleaning easier. Access to the
various parts of the engine is from the top and via side panels.
Engine oil filter
The engine oil filter offers a high level of filtration allowing the oil change
interval to be increased to 500 hours. It is easy to access and is positioned to avoid contaminating the
surrounding environment.
Air cleaner
The large capacity forced air cleaner removes over 99% of airborne particles,
reducing
the risk of engine contamination and making the cleaning and cartridge change
intervals
greater.
Fuel filter
High-efficiency fuel filtration is attained by the use of multiple filters, including a
fuel pre-filter fitted with a water separator that removes most moisture from the fuel.
Hydraulic oil return filter
The protection of the hydraulic system is made more effective by the use of glass fiber
filter
technology in the main oil return filter. This means that with more than 99,5% of
foreign particles filtered out, the oil change interval is increased.
7. Service:
Our commitment to total customer satisfaction extends worldwide. To keep your machine
and business up and running with Jingong uptime services that are proven to cut repair costs and unplanned
downtime. Jingong always takes customer needs as the starting point and provides customers with a full range of
services, including maintenance, repair, accessories, and value-added care.
8. Application range: mining, general engineering, municipal engineering, road engineering.
