Product Introduction
The GR5505 is a flagship motor grader product that focuses on high power, high efficiency and heavy-load operation. It is specially designed to cope with harsh working conditions and heavy leveling tasks, aiming to provide users with extremely high production efficiency and reliability.
Product Advantage
GR5505 overload motor grader hydraulic with engine is equipped with a double friction plate type worm gear box with overload protection, a high-modulus wear-resistant rotary gear ring, a reinforced traction frame, heat treatment of the guide rail, optimization of the blade arc, integral angle positioner, safe and reliable.
Electronically controlled double handle operation. Change the traditional multi-handle control mode and reduce the driver's control intensity by 70%. Efficient matching of power transmission system. It adopts a three-stage variable power engine, which has high reliability and fuel economy, low emissions, and meets the requirements of Euro III emission regulations. Equipped with a hydraulic transmission with a lock-up clutch, with the help of "automatic shifting" to achieve energy saving.

Product Operate Guide
Before starting work, walk around the machine to check and ensure there are no obstacles. After starting, idle for preheating. Only when the instrument display is normal can it be operated. Operate the electro-hydraulic handle to control the lifting, tilting and other actions of the scraper. When turning while driving, slow down. It is strictly forbidden to make sharp turns at high speed. Adhere to safety regulations and conduct regular maintenance to ensure efficient and smooth operation as well as the safety of both personnel and machines.
FAQ
1.What are the common fault warning signals?
Instrument alarm: Indicator lights such as engine failure, excessively high hydraulic oil temperature, and charging failure light up.
Abnormal sounds: Unusual noises from the engine, chassis or working device.
Performance decline: Slow movement, weakness, and difficulty walking.
Abnormal phenomena: Excessive black smoke, severe oil leakage.
If the above situations occur, the machine should be stopped immediately for inspection and professional service personnel should be contacted.
2.Is it easy to slip when working on muddy or soft ground?
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.
3.What is the maintenance cycle?
A: The maintenance cycle follows the principle of "first come, first served". Please strictly refer to the "Operation and Maintenance Manual" provided with the vehicle for specific details. It is usually divided into:
Daily maintenance (every 8-10 hours) : Inspect, clean and add grease around the machine.
Regular maintenance (such as 250 hours, 500 hours, 1000 hours, 2000 hours) : Replace engine oil, oil filter, air filter, hydraulic oil filter element, etc., and conduct a comprehensive inspection.
4.Is daily maintenance and upkeep convenient?
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.
5.What should I do if an alarm indicator light appears on the instrument panel during work?
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.
6.What could be the reasons for feeling that the vehicle is weak or moving slowly?
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.
