Synchronous detection method of double-beam bridge crane and cart motor? Is there a good way?

the simplest way is to jack up the end beams on both sides, and use a tachometer to measure whether the rotation speeds on both sides are consistent. If it is inconvenient, you can use a clamp multimeter to measure whether the currents of the motors on both sides are consistent in the same gear. If there are no abnormalities in the above two questions, please don't consider the electrical problems any more.

The mechanical problems include the following: 1. The driving wheels on both sides are inconsistent in wear, and there is a situation that one side is big and the other side is small. 2. The lower winding degree of the main beams on both sides is inconsistent, resulting in the formation of a figure of eight on the end beams on both sides. Measure whether the diagonal lines of the traffic are consistent. 3. Due to the long-term use, the position of the track is deviated, so consider readjusting it.

if there are no problems above, please consider looking for a crane manufacturer to help solve the problem, or you can contact me, but there is a charge.

I hope I can help you.
