Inspection Before Construction of Grader Equipment

 Affected by the epidemic, your equipment has experienced a long-term shutdown. After long-term storage in the cold winter, various oils and lubrication protections of the motor grader may change. If the machine is turned on and put into operation without a detailed inspection, it may Poor operation will occur. In order to reduce equipment failures and ensure the best performance of the machine, Komatsu Motor Grader should undergo detailed inspection and maintenance before starting work.


The first step: check before starting


1. Check the oil level and antifreeze level of each part


① Please park the Motor Grader on a level ground to ensure the safety of the surrounding environment.


②Check the engine oil, fuel and other parts; the oil level should be in the middle of the mark on the dipstick, and the fuel must be sufficient.


③The hydraulic and variable oil levels meet the requirements; if you need to add them, please select according to the fuel, coolant and lubricating oil table in the manual.

2. Check for traces of oil or water leakage


① Check whether there are traces of oil or water leakage. Pay special attention to high-pressure pipe joints and oil cylinders. Once a leak is found, check the leak and repair it.


②If it still leaks, please call Shantui's service hotline 400-666-3666, or use the Shantui eRoad APP for one-click repair.


3. Complete machine inspection


① Check bolts and nuts everywhere.


② Check the hand brake and foot brake.


③Tighten the front and rear wheel rim bolts, check the tire pressure, the front and rear wheels are 0.26-0.28Mpa.


④The grease inspection of the pin shaft and the rotating part.


Step 2: Power on and check


①Check the battery's electric eye status before power-on inspection: green means the battery is good, black means the battery needs to be charged, and white means the battery needs to be replaced.


②If the battery has been removed before shutdown, ensure that the battery has sufficient power before installation, and ensure that the battery is installed when the start key is off.


③Turn on the start switch after installation and check whether the battery is normal. Whether the original parts of the electrical appliances are normal.


Step 3: Start inspection


①After starting, check whether the instrument panel has alarm information, whether the machine has abnormal noise, and whether the speed is stable.


② Idling operation for 5-10 minutes, check whether the water temperature, oil pressure, charging voltage and other parameters are normal, and check whether the air conditioning heating function is normal.


③Operate the machine at idle speed to ensure the surrounding safety, move the working devices, use the low-speed gear to walk, observe for abnormal noise and oil leakage, and confirm that the brakes are good, and then walk in high-speed gear.


④When the equipment runs to the water temperature and the hydraulic oil temperature is above 45-55 degrees, it can work slowly at full load.


The Motor Grader Operation is normally and you can start using it

Reasonable Operation Of Track Bulldozer

图片
The  Track Bulldozer   has the greatest influence on the transmission oil temperature due to the external resistance and the maximum output torque during the shovel operation. If the small throttle is used for a long time to operate the torque converter in the inefficient zone, the transmission oil temperature will rise. If the large throttle is used during frequent shifting, it will cause severe impact on the machine and increase the temperature of the transmission oil. To this end, the operator should reasonably control the amount of bulldozer and the timing of the blade lifting and lowering. The soil feeding distance should not be too long, so as to prevent the use of small throttle for a long time. We are  Track Bulldozer Supplier , specializing in the production of machinery and equipment, welcome to consult and order.

How to Choose the Right Bulldozer?

图片
  Purchasing a bulldozer is a significant investment, whether you're in the construction business or need one for specific projects. To ensure you make an informed decision and get the   right bulldozer   for your needs, here are four essential tips and things to know before buying one: 1. Define Your Requirements and Applications The first step in   buying a bulldozer  is understanding your specific requirements and applications. Consider the following: Size and Capacity:  Bulldozers come in various sizes and capacities. Determine the size that can handle your typical projects and the type of material you'll be moving. Attachments:  Many bulldozers can be equipped with various attachments, such as blades, rippers, and winches. Assess which attachments you need for your tasks. Terrain:  Consider the type of terrain you'll be working on, as this can affect the tracks or tires your bulldozer should have. Understanding your specific needs will help you narrow down your options

No Steering Failure of Crawler Hydraulic Steering Bulldozer

图片
  During the use of the bulldozer, due to various reasons, the bulldozer is difficult to turn, cannot turn, cold cars can turn, hot cars can not turn. After the occurrence of these failure phenomena, according to the use time of the bulldozer and the occurrence process of the failure, the classification analysis should be carried out to check the truth, which can avoid unnecessary disassembly and reduce the internal pollution of the machine. The following   Bulldozer Suppliers   introduce common fault phenomena such as bulldozers and related knowledge of inspection and elimination. When the  Dozer  is in use, it suddenly fails to turn on both sides. The overflow valve at the oil inlet of the directional control valve assembly can be disassembled. The reason is that the oil is too dirty, the impurities in the oil wear or strain the surface of the overflow valve core and the inner cavity of the valve body, so that the valve core is stuck in the position where the oil return is turned on,
