Excavators often need uphill, downhill to complete the work, a little attention, there will be heavy accidents such as turning over, especially when the excavator breaks down easily. The action of the excavator on the downhill slope seems simple, but there are many ways in it. This is why some old drivers can make up and down the slope 6 of the action, but some beginners are only jealous.
Excavator downhill
In the construction process, the excavator will inevitably encounter a variety of working conditions, up to the cliffs, down to the shoal marshes. Today, the small editor to introduce to everyone is the main point of the excavator slope.
Attention to downhill matters
When the excavator is on the slope and is ready to downhill, do not be in a hurry to turn around. First, adjust the height of the big arm and the small arm, especially the height of the large arm as far as possible, the small arm retracted, and the turning radius and inertia force of the next step. When walking downhill, the upper wheel should be tightened to avoid the danger of sliding forward when the car body is moving under gravity.
When walking on the slope, the work device should be placed in front of the front to ensure safety. At the same time, the excavator must closely observe the bucket and whether there are no obstacles in the turn of the arms.
At this time, the middle line of the boom should not exceed the vertical centerline of the excavator, otherwise it will be transferred back to the center of gravity of the excavator and there is a potential danger of rollover. After parking, insert the bucket into the ground and put down the stopper on the track.
After the excavator has finished the rotary movement, the excavator head facing the slope can lift the big arm and the small arm, let the bucket move from 20 to 30 centimeters away from the ground, slow down to the slope, and prevent the excavator from sliding down uncontrolled because of the excessive inertia.
When the excavator is near the end of the slope, the large and small arms should be dropped to the ground to support the excavator to walk forward, otherwise the front side of the caterpillar may be stuck in the earth.
The bucket supports the ground so that the front part of the excavator is off the ground, and the excavator moves forward until the front part of the excavator lands again.
Warm reminding
If there is a bare rock, a snow, and a muddy slope of the water, even the old driver who is rich in experience should not do the downhill, because the danger hidden under this condition is unknown!
Try not to turn on the slope. It is not easy for an excavator's heavy body to make a turn on the slope. Under the condition of uneven force, it is easy to turn over.
If there are obstacles in front, do not crush the past by walking directly, clean and pass through, avoid foreign objects to increase the angle of the slope of the excavator, and affect the instability of the center of gravity.
The driver had better fasten the seat belt. The feeling of seat belt is easy to be ignored by many excavators, so for the sake of everyone's safety, Xiao Bian reminds me again at the end of the article.
Attaching the attention to the excavator climbing mountain:
1, do not do digging arm rotation action on the slope to prevent the center of gravity change leads to fuselage instability.
2. Avoid digging away from the surface of the slope especially when the bucket is full.
3, we must avoid excavators doing lateral movement on the slope, so it is easy to lose stability and roll over.
4, the excavator is also very dangerous in the downhill, so remember to put the bucket down to the ground 20~30 centimeters, parallel to the slope, the operation of the excavator with slow downslope, the steep gradient can allow the dug to support the brakes at first.
5, it is dangerous to change the direction of walking arbitrarily when downhill.
6, the average crawler angle of the crawler excavator is 35 degrees, and it is strictly prohibited to operate the excavator to climb the sloping land greater than 35 degrees.
The excavator is in the course of driving, whether uphill or downhill. First of all, we must guarantee the safety of our own. According to the action points introduced in this article, let the excavator show up with you.
