It perfectly combines the reliability of traditional machinery with the convenience of modern hydraulic technology. Through humanized design and optional intelligent systems, it helps users deal with various severe construction challenges. It is the ideal choice for users who pursue high efficiency, high quality and low comprehensive operating costs.
Energy-saving and noise-reduction: Low-speed engine transmission line is used, the specific point of the fuel consumption is low, energy saving and environmental protection; the transmission system is configured at low speed, the average fuel consumption is reduced by about 8%.
Using Dongkang High-efficiency State III Variable Power Engine. Improve hydraulic system pressure, blade rotary force is greatly improved, high-frequency quenching gear ring, wear resistance and life expectancy, to achieve load rotation. Increase the displacement of hydraulic pumps and hydraulic motors, and increase the speed of cylinders by 20%.

When operating the GR2403, please first read the manual and familiarize yourself with the functions of each joystick. Conduct a machine winding check before starting. During operation, the pilot hydraulic handle is used to precisely control the lifting, tilting, rotating and lateral movement of the scraper. Pay attention to maintaining a good line of sight and operate smoothly. Extra caution is required when working on slopes, and any violation of regulations is strictly prohibited. Daily maintenance and upkeep are the key to ensuring the efficient and long-lasting operation of equipment.
FAQ
A: It adopts hydraulic mechanical transmission. This system combines the high efficiency of mechanical transmission with the stepless speed regulation feature of hydraulic transmission, providing greater traction force, smoother operation and better fuel economy. It is particularly suitable for heavy-load operations.
A: The standard rear-wheel drive already has good performance, but customers can choose the all-wheel drive (all-wheel steering) function as an option. In harsh working conditions, enabling all-wheel drive can significantly enhance grip and passability, effectively prevent skidding, and improve the ability to get out of difficult situations.
A: Yes. The GR2403 supports the optional installation of GPS or laser automatic leveling systems. Through this system, high-precision automated leveling operations can be achieved, significantly reducing the reliance on the operator's experience, improving construction quality and efficiency, and is particularly suitable for precise leveling operations in large sites.
A: The design is very easy to maintain. The engine hood can be opened at a large Angle for convenient maintenance. The most important thing is that it is equipped with a centralized lubrication system as standard. Just add grease at one point, and it can quickly complete the lubrication of multiple important hinge points, saving time and effort and effectively extending the service life of the equipment.
A: Work should be stopped immediately. Refer to the manual to confirm the meaning of the alarm. Common ones include engine oil pressure alarm, excessively high water temperature alarm, etc. If it cannot be solved by yourself, you should immediately turn off the engine and contact the after-sales service personnel.
A: There could be many reasons, for example:
Engine fuel system issues (such as clogged filters, etc.).
Hydraulic system issues (insufficient hydraulic oil, clogged filter element, internal leakage in the system).
Improper operation (setting the gear too high).
It is recommended to start with simple checks (such as oil and filter elements). If the problem persists, it should be repaired by a professional technician.
