Product description
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 M11-C350 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 JGM934L 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.
