The meaning of protection level of electric single beam crane

The electric single-beam crane used in the workshop is usually used at a temperature of -20 to 40 degrees Celsius. The requirements for the electric single-beam crane are different depending on the workshop environment. Some workshops need to be explosion-proof, some are metallurgical, and there are When it comes to the protection level, its format is IPXX. The editor will introduce what is the protection level of the electric single-girder crane.

Generally, there is an IPXX logo on the nameplate of an electric single-girder crane. This logo represents the protection level of the crane. IP is its marking letter. The first X is represented by a number, which represents the level of contact protection and foreign object protection. The two Xs are also represented by numbers, which represent the waterproof protection level. Then the values of the two values and the range it represents are as follows:

The first X value and protection range:

0 No protection No special protection

1 Prevent the intrusion of objects larger than 50mm, and prevent the intrusion of objects larger than 50mm in diameter.

2 Prevent the intrusion of objects larger than 12mm,

3 Prevent the intrusion of objects larger than 2.5mm, and prevent the intrusion of tools, wires or objects larger than 2.5mm in diameter.

4 Prevent the intrusion of objects larger than 1.0mm, and prevent the intrusion of mosquitoes, insects or objects with a diameter larger than 1.0.

5 Dust prevention cannot completely prevent the intrusion of dust, but the amount of intrusion of dust will not affect normal operation.

6 Dust-proof completely prevents dust intrusion.

The second X value and protection range:

0 No protection, no special protection.

1 Prevent the intrusion of dripping water, and prevent water dripping vertically.

2 It can still prevent dripping water when it is tilted 15 degrees, and it can still prevent dripping water when the lamp is tilted 15 degrees.

3 Prevent the intrusion of sprayed water, prevent rain, or the water sprayed in the direction where the vertical angle is less than 50 degrees.

4 Prevent the intrusion of splashing water, and prevent the intrusion of splashing water from all directions.

5 Prevent the intrusion of large waves of water, and prevent the intrusion of water from the spray hole.

6 Prevent the intrusion of sprayed water and prevent the intrusion of large waves.

7 Prevent the intrusion of water ingress,

If the user's workshop environment has requirements for the protection level, it must be stated at the time of ordering to avoid that the purchased crane cannot adapt to the workshop environment.
