Explosion-proof electric hoist six tests

Explosion-proof electric hoist has to undergo rigorous testing before leaving the factory due to the special application environment and high safety requirements. The test contents of explosion-proof electric hoist mainly include six test: type test, routine test, medium test, sample test, life test, tolerance test, which is the test that must be carried out before each qualified explosion-proof electric hoist leaves the factory.
 
Type test: this is a test performed on an explosion-proof electric hoist manufactured in accordance with a design requirement, to verify that the design requirements meet certain specifications.
 
Routine test: Also called factory test, the test carried out in the manufacture or after the completion of each device or equipment of the explosion-proof electric hoist to determine whether the hoist meets the standards of use.
 
Media test: It is a general term for various tests to test the electrical properties of medium, including: insulation, static electricity, and withstand voltage.
 
Sample test: Several samples randomly selected from the explosion-proof electric hoist, are also tested to determine whether the sample meets the standard.
 
Life test: A test to determine the life of explosion-proof electric hoist under specified conditions, or a test to evaluate the life characteristics of an analytical product, is a destructive test.
 
Tolerance test: Testing if special explosion-proof electric hoist, such as repeated operation, short circuit, over voltage, vibration, shock, etc. under specified conditions, are destructive tests.
