Test Background
Mining machinery industrial products, after passing the basic performance test, should pass the relevant artificial simulated environmental test assessment based on the impact of environmental factors on various products. For mining environmental testing of mechanical products, different test items can be selected based on the impact of environmental factors.
Zhongke Testing Reliability Experiment Center has various environmental testing capabilities for mechanical products and provides professional mining environment testing services for mechanical products.
Scope of tests
General-purpose mechanical products used in mines and open-pit mine environments, including mining machinery, lifting machinery, mineral processing machinery, transportation machinery, rock drilling machinery, mining electrical equipment, etc.
