BE CAREFUL!

Hold the door frame when going downhill

The excavator uses the cooperation of the crawler and the working device, and has a strong off-road capability. It can climb up a very steep slope and can also easily go downhill. When going uphill or downhill, there is a danger that is easily overlooked, when the excavator is going downhill or down the trailer, the body will lean forward, so some drivers will habitually push the front windshield with their left hand on the glass or door frame, use the right hand to operate the excavator to walk. At this time, if the door is open and not locked, the door will be quickly closed due to gravity, resulting in a large closing force. At this time, if your hand is on the door frame, it will be clamped. Therefore, when the excavator enters the working state, whether the door of the cab is opened or closed, it must be confirmed that it is locked, and it is necessary to develop the habit of not holding the door frame by hand.

 

Raise the boom while driving

When driving an excavator, some novices or apprentices suppose that if the boom of the excavator is raised to the highest level, the stick is fully opened, and the bucket is facing the sky, there will be a better line of sight when driving. There are even people who are influenced by online videos and think that it will be cooler to rotate while walking, which is very dangerous in practice. Because when the working device of the excavator is in a high position, the center of gravity will be high, and a slight unevenness on the ground will lead to overturning. Therefore, it is most important to focus on driving and see the road ahead clearly.

 

Driving on soft ground

When the excavator works on soft ground such as swamps and river beaches, it is necessary to use a bucket to test whether the ground can bear the weight of the excavator. If this process is forgotten, it may lead to serious consequences. Although the excavator is designed with crawler tracks and has a large area of contact with the ground, it sometimes happens that the excavator falls into the mud and cannot move due to improper operation. Therefore, when working on soft ground such as swamps, river beaches, etc., you should pay attention to:

• Use a bucket to test the ground hardness
• Do not stay in the same place for a long time
• Walk more straight and less turns
• In case the excavator gets stuck in the mud, don't try to climb out with a set of methods, it will only get deeper and deeper. There are many ways to rescue:
• If the sink is not too deep, first hollow out the middle of the two tracks and try again.
• If you still can't get out, first try to see how deep the mud is. If it is not very deep, just dig up all the mud in front of you, make your own way, and slowly approach the hard ground on the shore.
• If the silt is infinitely deep, find some iron plates or road substrates, and pad them under the tracks horizontally, which can also help to get out of trouble.

 

Blind sight

The cab of the excavator is on the left, the middle passive arm blocks the line of sight, and there is a large blind spot on the right side, especially the rear right cannot be seen. Many excavator accidents are caused by blocking the line of sight when the right side of the tail is rotating. Therefore, when working on a not wide site, the excavator should try to move to the left, leaving more space on the right side. The rear-view mirror is a fragile part on the excavator, and it is often knocked off during work or transportation. Many drivers will feel that it isn’t necessary to replace it. In fact, the rearview mirror, especially the right rearview mirror, is more important on excavators. Accidents tend to be caused by poor safety awareness.

 

Riding on the ditch to work

When the excavator is digging a ditch, if the construction worker tells you that the height in front of you is wrong and asks you to ride on the ditch to dig again, be careful about that. Because no matter what the geological conditions are, you can only go back half a crawler extremely, or there will be the danger of collapse. Even if the worker says there’s no problem to move a little more. A qualified driver should have his own independent thinking and safety awareness, which is the premise to avoid danger and the basic professional ethics.
