In order to ensure the safe use of explosion-proof electric
rope hoist, electric hoist in the factory have to go through the following six tests.
Type test: in accordance with the design requirements of a manufacturing explosion-proof electric hoist tests conducted to test this design meets certain specifications.
Conventional test: also called factory test, explosion-proof electric hoist each device or device during manufacture or after the completion of the tests carried out to ascertain whether a particular device or equipment standards.
Test medium: to test the electrical characteristics of various test medium in general, comprising: an insulating, static electricity, voltage, etc.
Sample test: explosion-proof electric
wire rope winch several randomly selected sample test, the sample is also used to ascertain whether a particular standard.
Life Test: To determine the required proof hoist may reach the life conditions of testing, or for the evaluation and analysis of the product life characteristics of tests carried out are destructive tests.
Tolerance test: including certain period of time taken for a certain purpose other provisions specific operating conditions,manual block the explosion-proof electric hoist tests carried out, such as the repeated operation, short circuit, over-voltage, vibration, shock, etc., is a destructive test.
