Many mines use mine car, and the safety of tramcars is one of the important factors to improve efficiency. Below, I will introduce the importance of the accessories on mine car - anti falling devices!
The mine car is a lifting container used for inclined shaft lifting, which can lift coal and gangue, and lower materials, lifting personnel, and equipment.
The basic components of a mining car are the carriage, frame, wheel sets, and connectors. The connector consists of a traction chain, a pin, and a pin seat, and is a component that involves significant safety issues. Therefore, when transporting in inclined shafts, the connection between tramcars and the connection between mine car and steel wire ropes must use a connection device that cannot fall off itself and be equipped with a safety rope. Therefore, the pin of the mining car connector must have an anti falling device. The application shows that the locking ring type anti falling device has a good effect.
When various safety chains and connecting rings, chains, and pins of mining cars are produced in batches, sampling tensile tests must be conducted. If they do not meet the requirements, they must not be used. Before initial use and every 2 years after use, the test must be carried out one by one with a tensile force equal to 2 times the maximum static load. If cracks or permanent elongation exceeds 0.2% are found, they must not be used.
