The 03A bridge is a steering bridge with a wet brake. As an underground operation vehicle, the whole bridge has passed the transmission test and the bridge shell fatigue test, which has high safety and reliability.
The whole bridge and the rigid suspension of the frame can be used with 07A to meet the needs of underground transportation. The whole bridge structure absorbs the advantages and disadvantages of domestic and foreign industry benchmark products, learns from the strengths and makes up for the shortcomings, and has high stability and service life. This product can effectively eliminate the dependence of relevant domestic host manufacturers on foreign products.
