Mechanical problems include the following: 1: The wear of the driving wheels on both sides is inconsistent, with one side large and the other small. 2. The deflection degree of the main beams on both sides is inconsistent, which leads to the formation of splayed end beams on both sides. Measure whether the diagonal lines of flow are consistent. 3. Due to the long-term use, the track position has deviation, so consider readjusting.
If there are no problems above, please consider asking the crane manufacturer for help, or you can contact me, but there is a charge.
I hope I can help you.
