Precautions for using variable frequency bridge crane
Bridge crane is a common lifting equipment, and the frequency converter is one of the important components of this equipment. The frequency converter can adjust the speed of the motor to control the operation of the lifting equipment. This article will introduce the relevant content of the operation of frequency converter for bridge crane.
1. Start preparation
Before starting the machine, check the status and operation of the inverter and its related equipment, and ensure that the inverter is firmly installed, wired correctly, and grounded well. Before starting the machine, make sure that the power input is normal and stable, and that the interfaces of all parts are tightly connected and not loose.
2. Frequency converter operation control
The frequency converter can realize the frequency adjustment of the 15 ton overhead crane motor, thereby changing its operating speed. According to actual needs, the operating frequency and speed can be set through the frequency converter to control the operation of the equipment.
In bridge crane operation, the frequency converter adopts automatic control mode. Various protection parameters during operation can be preset in the frequency converter, such as overload protection, overvoltage protection, undervoltage protection, etc.
3. Control panel operation
The control panel of an 15 ton overhead crane generally includes a main circuit breaker, operation switch, emergency stop switch, speed adjustment knob, etc. When operating an overhead crane, you need to be familiar with the functions and operating methods of each control on the control panel.
The main circuit breaker is used to control the power input and output of the equipment. In line with the principle of safety, when switching the main circuit breaker, you must ensure that it is done in a safe state.
The operation switch is used to control the operation of the lifting equipment. There is usually a "start" switch and a "stop" switch on the control panel.
The emergency stop switch is used to urgently stop the operation of the lifting equipment when the bridge crane is in danger or malfunctions. When operating the control panel, you must always remain vigilant and pay attention to the operating status of the lifting equipment to ensure safe operation.
The speed adjustment knob is used to adjust the speed of the lifting equipment by manually rotating the speed knob according to actual needs.
4. Operation precautions
When operating the bridge crane frequency converter, the following points should be noted:
(1) According to the load status of the equipment, reasonably set the operating parameters of the frequency converter to ensure stable operation of the equipment.
(2) During the operation of the equipment, always pay attention to the status and operation of the equipment, and shut down the equipment in a timely manner if abnormal conditions are found.
(3) When operating the control panel, carefully observe the status changes of each sign and indicator light to ensure correct control operations.
(4) When operating the inverter, the equipment operating procedures should be followed to ensure safe operation.
In short, the operation of the frequency converter of the bridge crane is an important part of the operation control of the lifting equipment. Proficient in the operation method of the frequency converter and rational use of the frequency converter for operation control can improve the operating efficiency and safety of the equipment.
