How to eliminate the short circuit of the lifting column!

The lifting column is the main force of outdoor intelligent vehicles. It has a great use in the direction of vehicle flow and vehicle shunting. However, if a short circuit occurs during use, it will be a very headache. Especially in the hot summer and long-term working circuit heating, it is not only easy to cause short circuit, but also easy to cause the lifting column motor or electric box to burn out, resulting in the hydraulic lifting column being paralyzed and unusable. Therefore, it is very important to check the wiring. So how to check the line and eliminate it step by step? There are three main steps:

Step 1: Check whether the lifting column circuit is aging, exposed or damaged. Turn off the power, and then measure through the circuit schematic diagram, and analyze the fault point according to the measured resistance value.

Step 2: After turning on the power, check whether the indicator light of the lifting column electrical box works to eliminate the short circuit between the power supplies. At this time, a large short-circuit current will be generated and the melted fuse will be burned. This situation is obvious, so it can be detected and eliminated during circuit analysis.

Step 3: Carry out the no-load and load test of the lifting column to check whether the relay can be freely connected. When the contacts are glued, the switch will not release continuously. When such a short circuit occurs, no large current will be generated and the fuse will blow. The device will not be damaged.

These three steps can eliminate the short circuit phenomenon of the lifting column one by one, and also can quickly find the problem and solve it quickly.

Lifting the column to perform line short-circuit troubleshooting is a responsible and responsible performance, and can not be sloppy, and the normal work of the lifting column can improve work efficiency, the best of both worlds. This also reminds us that it must be sloppy when performing regular maintenance on the lifting column.
