Operating regulations to be observed during micro excavator lifting operations.
Please observe the following operation regulations:
1, mini excavator installation to meet the lifting needs of the bucket hook, prohibit the direct sling set on the bucket teeth; before the operation should strictly check whether the hook is intact.
Many people think that the excavator is a digging machine, used to load a car, dig a ditch or level the ground. In fact, excavators can also do many kinds of work, such as crushing, demolition, lifting and so on, these are excavators often have to do the work. For the novice, excavator lifting is a very dangerous operation, today we two chat about lifting operations need to pay attention to the place!
Excavator lifting generally use the bucket to hook up the object, according to the different objects lifting, you can use the hook behind the bucket, you can also hang directly on the bucket teeth. These two hooking places should be determined according to the actual situation, otherwise it will cause safety hazards.
There is a hook at the back of the bucket in general, and it is safe to use this place for lifting, especially when the object needs to be lifted to a certain height, if the rope hangs on the bucket teeth, it is easy to slip off in the process of lifting. The use of hooks ensures that the rope will not slip and is the recommended safe lifting method.
Is lifting with bucket teeth not recommended at all? Of course not, when the object to be lifted is very close to the excavator, it is very suitable to use the bucket teeth to directly hook the object. In addition, if the lifting distance is not very high, the bucket tooth hook is also very convenient.
2.Stabilization of the lower plate to prevent rollover
For martial arts practitioners, is to pay attention to the lower plate stability, waist and horse unity in order to play a large force. For excavator lifting is the same reason, stand stable body is the precursor of safe operation.
To prevent the excavator from tipping, lifting the excavator must stand on a horizontal stopping surface; if the object is lifted on an inclined surface, you can first dig out a horizontal stopping surface.
In addition to the stopping surface, the direction of the excavator chassis is also very important, lifting direction and the chassis track direction of the smaller the angle of the excavator the more secure, the larger the angle is more likely to cause the excavator overturned.
Mini excavator in lifting, in fact, is a lever state, always pay attention to the lifting object center of gravity to the excavator center of gravity distance. The closer the lifting object is to the center of gravity of the excavator, the safer the excavator is, and the lifting capacity can be played to a large extent; the farther the lifting object is from the center of gravity of the excavator, the greater the danger of the excavator tipping over, and the more limited the lifting capacity of the excavator.
3. Reasonable operation Safety
In the lifting should pay attention to reasonable maneuvering order, priority to lift the big arm, when the big arm in place can open the small arm and bucket, will also play a certain lifting effect.
Lifting objects is to pay attention to, do not need to lift too high when must not lift too high, once the excavator has the danger of tipping, to time to lower the big arm, will be lifting the object quickly on the ground.
Sometimes excavators in lifting objects, not only to do vertical lifting and lowering, but also to place the object into a certain angle position. At this time, you need to cooperate with the command gestures of the construction personnel on site, and when rotating to adjust the angle, you need the tracks and slewing to move at the same time.
