Every design of the excavator is not for nothing, many of you have had the experience of feeling that a certain design of the excavator is rather strange, and even some incongruity, in fact, this is not the problem of the designer, is the hidden function of the excavator!

Today I would like to introduce you to a small ring on the back of the bucket, seemingly useless or even inconspicuous a small ring, the role can be a big go! Do not believe in a look!

Hook hole

In the construction site for a period of time in the machine friends know that the excavator not only to do the work of the excavator, sometimes also need to guest crane role, so the back of the bucket is a small ring is also known as the hook hole parts, is the excavator transformed into a crane necessities.

For example, in the construction site, the operator can use the hook hole to complete the lifting of stones, steel plates, pipe fittings and other materials.

Function principle

There is no doubt that the excavator arm is at 90 degrees when the digging force is the largest, and similarly, it can also maintain this position when lifting large objects. The object to be lifted, the body and the crawler should be kept in the same line, which can play a role in stabilizing the center of gravity.

Excavators equipped with dozer shovels can be lifted by supporting the shovel on the front, which can play a certain role in adding force.

Although the excavator more lifting function, but after all, is not pure lifting machinery, so there are some potential risk factors need to be carefully avoided.

Dangerous factors

1, the crane is equipped with the rope is after many experiments, so when you operate the excavator for lifting operations, be sure to use a reliable rope, and according to the lifting object size, weight appropriate adjustment of the length of the rope.

2, too large, too long or the weight of the object is too heavy, we must not force the excavator lifting, because the excavator can withstand the weight is limited, forcible lifting is likely to cause the excavator center of gravity shift, and in serious cases may cause a rollover accident.

3, many friends in order to figure the convenience of the direct use of bucket teeth to hook the sling to complete lifting operations, this approach is very undesirable, on the one hand, bucket teeth are very easy to slip, on the other hand, once the object falls is likely to hit people!

4、Avoid too much haste! The lifting operation itself is not the excavator’s expertise, so we must move slowly in the lifting process, regardless of the size of the arm, or walking device can not move too fast.
