Precautions for safe operation of excavators
Precautions for safe operation of excavators:
- Check before operation to confirm that everything is complete and intact, there are no obstacles and other personnel within the range of movement of the boom and bucket, and the operation can only be started after sounding the whistle to warn.
- When excavating, the soil should not be too deep each time, and the lifting bucket should not be too strong, so as not to damage the machine or cause overturning accidents. When the bucket falls, be careful not to impact the track and frame.
- Those who cooperate with the excavator to clean the bottom, level the ground, and repair the slope must work within the turning radius of the excavator. If it is necessary to work within the slewing radius of the excavator, the excavator must stop turning and brake the slewing mechanism before it can work. At the same time, people on and off the plane must take care of each other and cooperate closely to ensure safety.
- Vehicles and pedestrians are not allowed to stay within the range of excavator loading activities. When unloading materials on a car, wait until the car stops and the driver leaves the cab before turning the bucket and unloading materials on the car. When the excavator is turning, try to avoid the bucket from passing over the top of the cab. When unloading, the bucket should be lowered as much as possible, but be careful not to hit any part of the car.
- When the excavator is slewing, the slewing clutch should be used to cooperate with the slewing mechanism brake to rotate smoothly, and sharp slewing and the emergency braking are prohibited.
- Before the bucket leaves the ground, it is not allowed to turn, walk and other actions. When the bucket is fully loaded and suspended in the air, it is not allowed to lift the boom and walk.
- When the crawler excavator is moving, the boom should be placed in the forward direction of travel, and the height of the bucket from the ground should not exceed 1 meter. And brake the slewing mechanism.
- When the excavator goes uphill, the driving wheel should be at the back and the boom should be at the top; when the excavator is going downhill, the driving wheel should be at the front and the boom should be at the back. The up and down slope shall not exceed 20°. When going downhill, you should drive slowly and not shift gears or slide into neutral on the way. When the excavator passes through the track, soft soil, and clay road, it should pave the backing board.
- When excavating loose-grained soil on a high working surface, larger stones and other sundries in the working surface should be removed to avoid accidents caused by the collapse. If the soil is dug into a suspended state and cannot collapse naturally, it needs to be handled manually, and it is not allowed to smash or be pressed down with a bucket to avoid accidents.
- The excavator should not be too hasty when walking and turning. If the curve is too large, it should be turned in stages, within 20° each time.
- When the electric excavator is connected to the power supply, the capacity breaker on the switch box must be taken out. It is strictly forbidden for non-electricians to install electrical equipment. When the excavator is walking, the cables should be moved by staff wearing pressure-resistant rubber shoes or insulating gloves. And pay attention to prevent the cable from scratching and leakage.
- When the excavator is working, it is strictly forbidden to carry out repair, maintenance, fastening and other work. If there are abnormal noises, peculiar smells, excessive temperature rise, etc. during the work, stop the machine immediately for inspection.
- When maintaining, overhauling, lubricating and replacing the pulley at the top of the boom, the boom should be dropped to the ground.
As one of the most common equipment in construction machinery, excavators are widely used in harsh environments such as mines, water conservancy, municipalities, and highways. These occasions usually hide many large and small safety hazards. Mastering the precautions for safe operation of excavators will be of great help to friends who are about to engage in excavator driving. If you have friends who are engaged in this industry, please share this article with him. A little more safety, more guarantee!
