Excavator rainy season construction guide!

[BONOVO]

With the coming of summer, the rainstorm increases, which can bitter a large number of construction machinery workers, it rains continuously, the water is serious, the excavatorwork can be described as dangerous, especially the loose soil in the mountainous area, there is a landslide risk at any time. When excavators face such environmental operations, Jiangxi Kato reminds you to pay attention to the following matters!
First, do the preparatory work - reconnaissance and tools
In fact, a lot of trapped cars can be avoided, obviously too much water mud, a look at the place where the silt is deep and can not go down, do not have a lucky mind, as the boss or please complete the water and land excavatoris better. If the construction period is not urgent, you can drain the water first, let the site dry for a few days, and then start the operation when the soil becomes hard.
As the owner and operator of the machine, do fish pond and silt such work must be with steel rope and steel plate, can not easily go down.
Before starting, use the bucket to insert the bottom of the pond and the slope, to see the hardness of the mud, generally put down the bucket can be submerged to 3/4 of the place to be careful, if the whole bucket is submerged, this job is best not to pick up.
In particular, it is necessary to remind that some of the bottom surface of the pond has dried, but after a few tens of centimeters down is sand or mud, if you do not find out clearly, you will definitely trap the car; Sometimes the bottom of the pond is hard, but the slope is full of mud, which will cause the machine to sink downhill.
Second, pay attention to downhill - leave a good way out
First of all, pay attention to the downhill, if the posture is not accurate, it will overturn or trap the car, when you go down, you must think about how to come up, and you must leave a good way out.
According to the experience of netizens, there are the following matters for reference:
Don't go down the slope. It's better to go down 90 degrees
Never put the bulldozer in front of you when you're digging through the mud
The silt driving wheel goes down first and guides the wheel to the direction of the retreat
When the driving wheel climbs up the slope, the adhesion of the track is larger than that of the guide wheel. If the guide wheel climbs up the slope, the upper part of the track is tightened, and the large spring behind the guide wheel will buffer the explosive force of the driving wheel. When the vehicle has signs of sinking, if you pull the forearm hard, it is over.
Keep your forearms wide and pull with the bucket, keep your forearms wide, maybe you have a chance to escape. When you get into the mud pit, push the dry dirt forward, push the mud to the front, and then work. For a 20-ton car, the sludge needs to be padded with 60 cm thick dry soil.
Third, precautions in the operation - gentle and timely exit
1, in the mud operation, the action must be gentle, to avoid the machine shaking violently, so that it will sink quickly.
2, you can use the forearm to drag the car, the car a little bit up, and then a forearm car directly forward, so as to avoid the mud above the layer of hard shell crushed.
3, when it is found that the chain has been trapped in half to exit in time, do not think that a few more fights do not matter, to know that this is the critical point, and then it is difficult to come out.
4, always pay attention to the chain belt around, the excavatorchain belt imbalance does not use force, do not idling, once idling will stir up the soil on that side, the machine will tilt to the idling side, it is likely to overturn.
5, do not extend the whole bucket into the rotten mud, especially the kind of viscous mud, it is difficult to lift.
6. If the excavator has water on the hard bottom slope, the whole machine will slide down once the forearm is collected.
7, working at the water's edge, the working face of the excavatoris on the mud and almost the height of the water, try not to make the working face lower than the water, it is easy to dig more and more rotten.
8, dig the kind of slimy layer of mud "such as coal ash" it is best to put the excavatorstraight to dig, don't be afraid of trouble, found that it can quickly retreat, in case of collapse or get out.
9, if the chain with the whole fall, but the fuselage is still in the mud surface of the upper layer can keep turning then you can save yourself, must be calm do not panic, you can try to pull the mud under the car out of the point, try to pull the point in front, you can "float" in the past like a boat, if the car will go down do not operate, directly waiting for rescue.
10. If you really sink, dig up the mud under the chain, and it is possible that the chain is sucked by the mud.
11, under the chain belt cushion steel plate, iron plate, wood board, in short, on the hard plane, so that the machine can borrow.
12, pay special attention to, when you judge that the machine has been trapped, and as long as a little move will continue to fall, do not have any action, otherwise the deeper the deeper, the greater the loss.
Fourth, wait for the follow-up work of the rescue
If you can't save yourself, you have to ask for help. Before waiting for other machines to save the trapped vehicle to see if there is no water, if not, it should be prevented, if the rescue time is relatively long lest something similar to a sudden rainstorm occurs, the machine is easy to be flooded more severely, especially in the south, such as digging drainage ditches.
It doesn't matter if the excavator is broken where the fault is more trouble.
After the machine is pulled up, the cleaning work is done. When the cold car is washed thoroughly with a high-pressure water gun, the cab can also be washed directly with water. Trapped car is really a headache and a vexing thing, destroying the car and delaying the accident, the cost of rescue is also quite high.
Warm reminder: Take the job must be careful, do what you can, if the work has already begun, then be sure to do the preparatory work, any accident as long as the prevention can greatly reduce the probability of occurrence, do not fluke, do not greedy, do not feel that more than a few buckets are a few buckets, always observe, early exit.
