2025 05/09

Due to the particularity of the application environment and the high requirements for its own safety, explosion proof electric hoist must undergo strict testing before leaving the factory. The test contents of explosion proof electric hoists mainly include type test, routine test, medium test, sampling test, life test, and endurance test. These are the tests that must be conducted before each qualified explosion-proof electric hoist leaves the factory.

Type test: A test conducted on an explosion proof electric hoist manufactured according to a certain design requirement to check whether the design requirement meets certain specifications.
Routine test: Also called factory test, it is a test conducted on each component or equipment of an explosion proof electric hoist during manufacturing or after completion to determine whether the component or equipment meets a certain standard.

Dielectric test: It is a general term for various tests that test the electrical characteristics of media, including: insulation, static electricity, withstand voltage, etc.
Sampling test: Testing a number of randomly selected samples from the explosion-proof electric hoist is also used to determine whether the sample meets a certain standard.
Life test: A test to determine the possible life span of an explosion-proof electric hoist under specified conditions, or a test conducted to evaluate and analyze the life characteristics of the product, which is a destructive test.
Withstand test: Tests conducted on explosion-proof electric hoists under specified conditions including specific operations for a certain purpose within a certain period of time, such as repeated operations, short circuit, overvoltage, vibration, impact, etc., are destructive tests.
