In heavy engineering projects such as earthwork, road maintenance and mining operations, Komatsu graders are widely used in various engineering projects due to their excellent leveling ability and durability. Whether it is a new machine or a second-hand grader, safe operation is always the top priority. This article will focus on the safety points in the operation of Komatsu graders, from equipment inspection, driving operation, daily maintenance to common accident prevention, etc., to provide a comprehensive analysis to help operators and project managers improve their safety awareness in operations.
If you need to buy or wholesale high-quality second-hand excavators or Komatsu graders, please contact Jiecheng second-hand excavator supplier, email: guo@machbro.com, official website: https://www.machbro.com.
Engine oil check: confirm whether the oil level is within the normal range to avoid dry burning.
Hydraulic oil and brake oil: check whether the hydraulic oil tank and brake oil tank are leaking and whether the oil quality is deteriorating.
Cooling system: ensure that there is sufficient coolant in the radiator tank to prevent high temperature.
Tire pressure and damage inspection: including tire wear, bulges and cracks.
Brake function test: Before starting, press the brake to confirm whether there is resistance and normal response.
Dashboard function inspection: Confirm that various indicator lights and alarm sounds are working properly.
Electrical circuit safety: Confirm that lights, horns, reversing alarms, etc. are all available.
Work area inspection: Check obstacles, wires, and crowded areas.
Wear protective equipment: such as safety helmets, safety shoes, reflective clothing, etc.
Before entering the cab, sound the horn to warn;
Insert the key, release the parking brake, press the brake, and then start the ignition;
After starting, preheat for 3-5 minutes and observe whether the instrument is abnormal.
Master the steering skills of the front and rear frames: Komatsu graders use articulated steering, and you must be familiar with its steering radius and operation delay;
Adjust the blade angle and downforce: Make fine adjustments according to the operation requirements to avoid blade slippage or cutting too deep;
Keep the operation route straight: Set a reference point to avoid serpentine movement.
No high-speed turning: It is easy to cause rollover;
No gear shifting or reverse on the slope;
Fatigue driving and drunk operation are strictly prohibited.
Clean the dirt attached to the blade to prevent rust;
Check whether the hydraulic oil has been significantly reduced;
Check whether the lights and reverse buzzer are working properly.
Item | Maintenance cycle | Main content |
Engine oil change | Every 250 hours | Change the oil and oil filter |
Hydraulic system inspection | Every 500 hours | Change the hydraulic oil and check the aging of the oil pipe |
Air filter cleaning | Every 100 hours | Remove dust and replace if necessary |
Battery inspection | Once a month | Check the electrolyte and confirm that the terminal is not corroded |
Hydraulic cylinder inspection | After each operation | Check for oil leakage and piston rod scratches |
Check for traces of welding repair;
Whether the main components (engine, gearbox) have been replaced;
Require the supplier to issue maintenance and repair records.
Hydraulic system heating: mostly due to insufficient oil or oil deterioration;
Unstable direction: mostly due to loose steering hinge pin or lack of oil;
Engine weakness: may be caused by blockage of the intake filter or carbon deposits on the fuel injector.
Rollover accidents: often occur on slopes or sharp turns, and the speed must be controlled and the terrain must be assessed in advance;
Mechanical clamping accidents: the equipment must be turned off when getting on and off the vehicle to avoid accidentally touching the handle and causing the blade to move;
Blind spots causing collisions: it is recommended to install auxiliary cameras and reversing radars.
Regularly organize operator training and assessments;
Establish equipment use registration and handover system;
Emergency response plan: such as mechanical fire, hydraulic pipe burst, rollover rescue, etc.
Specialized in the recycling and sales of second-hand Komatsu graders and excavators;
Provide complete equipment inspection reports and refurbishment records;
Can recommend suitable models and working hours according to customer project requirements.
