The reason why pneumatic chain hoists need to undergo cold resistance testing (i.e. performance testing in low-temperature environments) is mainly based on the following considerations:

1、 Ensure the normal operation of equipment in low-temperature environments

Material properties:

In low-temperature environments, the properties of many materials will change, such as increased hardness and decreased toughness. These changes may cause equipment to experience issues such as lagging and breakage during operation.

Through cold resistance testing, the performance of pneumatic chain hoists at low temperatures can be evaluated to ensure that they meet design requirements.

Sealing performance:

Low temperature may cause the seal to harden and shrink, thereby affecting its sealing effect.

The cold resistance test can verify the sealing performance of the pneumatic chain hoist at low temperatures, ensuring that gas does not leak and maintaining the normal operation of the equipment.

2、 Improve the reliability and durability of equipment

Prevent malfunctions:

Through cold resistance testing, potential faults and hazards of equipment in low-temperature environments can be identified in a timely manner, such as poor lubrication and loose components.

Preventing these failures in advance can improve the reliability and durability of the equipment, and reduce the cost of maintenance and component replacement.

Extend service life:

Low temperature environments may cause additional wear or damage to certain components of the equipment.

Through cold resistance testing, the wear and tear of these components at low temperatures can be understood, and corresponding measures can be taken to extend their service life.

3、 Meet the needs of specific application scenarios

Cold regions:

In cold regions, pneumatic chain hoists may need to work for long periods of time in low-temperature environments.

Through cold resistance testing, it can be ensured that the equipment can still operate normally under these extreme conditions, meeting the needs of users.

Special industries:

Some special industries, such as cold storage and polar scientific research, have strict requirements for the low-temperature performance of equipment.

When pneumatic chain hoists are applied in these industries, they must pass cold resistance tests to prove that they meet relevant standards and requirements.
