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 operating speed of the bridge crane refers to the operating speed of each lifting mechanism, the unit is m/s, which is commonly used in engineering. Increase speed: increase the speed of the motor at the rated speed is indicated by VN. The general lifting speed is 8-12m/min, and the maximum lifting capacity is 1-4m/min. The operating speed of the cart: The operating speed of the vehicle at the rated speed is indicated by VK. The running speed of the cart is generally 80-120m/min, and the running speed of the trolley: the running speed of the motor at the rated speed is indicated by VT, and the running speed of the trolley is generally 30-50m/min.

The operating speed of the bridge crane is determined according to the specific operating requirements. Generally, bridge cranes are used, and the operating speed is moderate, and the power of the driving motor cannot be too large. Devices sometimes require lower operating speeds. When lifting small weight goods, work efficiency and speed should be improved. Used for lifting heavy objects, stable operation and low speed. When the track of the bridge crane is short, it is not suitable to use at high speed, and avoid running to the other end at high speed.
