What are the characteristics of bridge cranes?

If the bridge crane has the following advantages, it can be regarded as a stable equipment. The electrical system is simple and straightforward. Many communication contactors of traditional cranes have been abandoned. The contactor uses high-fault components and speed-regulating resistors to improve the reliability of the equipment. Due to the soft start effect of variable frequency speed regulation in the mechanical structure and transmission part, the problem of repeated high torque impact on the mechanical part is better solved. The important thing is that the failure rate has been greatly improved, and the failure rate has been zero for nearly one year after the overhaul. From the perspective of investment income, the annual repair cost of the old crane is about 25,000 per year. According to this estimate, the investment can be recovered within two years.

The above four items are summed up after the user transforms the lifting equipment. Before that, someone received a customer. The user's 5 bridge cranes are all traditional cranes. In the beginning, the speed of the wound motor was adjusted by short-circuiting the resistance of the motor rotor loop. After years of use, the amount of equipment repairs is increasing, the electrical components and transmission parts are damaged, and the safety and reliability are very poor. In fact, this is also a common problem in old bridge cranes. The above-mentioned equipment has been modified by the control system. After the summary.

It can be seen that the variable frequency drive of bridge cranes is the best solution for today's hoisting machinery and will become the standard equipment for subsequent cranes.
