Heavy duty work equipment
In order to cope with the heavy-duty working conditions of mining, 300HP motor grader GR3005 develops a friction disc worm gear box with overload protection, which can automatically slip when it is impacted to protect the safety of machines and people. The large modulus and high wear-resistant slewing bearing ensures that the machine can work normally for a long time under high-strength and harsh working conditions. The strength of the reinforced traction frame is reliable through CAE finite element analysis. The guide rails are heat treated to meet the dusty and soily working conditions of mines.
Electric control double handle operation
300HP motor grader GR3005 changes the traditional multi-handle manipulation mode, reducing the driver's manipulation intensity by 70%. All the original movements (including steering) can be operated with two electronic control handles. The meaning represented by each action of the handle can be displayed on the display on the console, and the driver can intuitively see the action of the oil cylinder caused by the action of the handle.
Efficient matching of power transmission system
The 300HP motor grader GR3005 adopts a three-stage variable power engine, which has high reliability and fuel economy, low emission, and meets the requirements of Euro III/National III emission regulations. Equipped with imported hydraulic gearbox to achieve energy saving with the help of "automatic shifting", the gearbox automatically shifts up and down according to "load change-vehicle speed change", so that the machine always maintains the "best working state" and reduces power loss.
Load sensing hydraulic system
Load sensing hydraulic system, equipped with variable piston pump and load sensitive multi-way valve, each main reversing valve and pressure reducing valve are proportional valves, and the control principle is that the current signal controls the pilot pressure (proportional pressure reducing valve) to operate the witching spool (main reversing valve), the pilot pressure is used to control the spool, the operating force is small, and the hysteresis is small. At the same time, the cylinder speed of the 300HP motor grader GR3005 is synchronized when the engine is idling and at high speed. The power loss of the system is lower, and the efficiency is much higher than that of the conventional hydraulic system. It realizes the synchronization of multi-way manipulation and compound action, and the manipulation is simple and comfortable.
Double-circuit wet brake mine rear axle
The 300HP motor grader GR3005 adopts a dual-circuit hydraulic braking system, which acts on the four middle and rear wheels of the grader. At the same time, the braking method of the machine adopts reliable multi-disc wet braking to ensure safe and stable braking. Optional drive rear axle with gear transmission balance box.
Cab ergonomics
The ROPS & FOPS cab used in the cab meets the ISO standard. Equipped with integrated heating and cooling air conditioning, adjustable suspension seats, with wipers and defroster to increase the comfort of operation. The cab is spaciously designed, and an advanced and reliable shock absorption device is installed to buffer the vibration of the cab. When machine is working, the double handle operation greatly reduces the labor intensity.
Fault diagnosis and GPS remote control technology
The engine and gearbox are equipped with automatic fault diagnosis function, and at the same time communicate with the engine and gearbox CAN bus through GPS. The relevant information of the engine and gearbox, such as engine speed, hours, water temperature, gearbox gear and other information can be monitored in real time through the GPS platform, and historical records can be saved to realize remote control.
