Reasons and solutions for the failure of electric advertising hooks

Classification:


During the use of the electric advertising hook, it is inevitable that there will be malfunctions. Maintaining the safe operation of the advertising hook, and timely and accurately handling various faults during operation are an important part of the use of the hook. Combined with installation and maintenance experience, the editor of Hunan Zhibo summarized the causes and solutions of some common failures of advertising hooks:

zhibo

(1) No power: Whether the power supply system is sending power to the advertising hook power supply, generally use a test pen to test, if there is no power, wait until the power is sent to work;

(2) Lack of phase: the main and control circuits of the advertising hook are damaged, the circuit is disconnected or the contact is poor, and the motor cannot be energized. In this case, the main and control circuits need to be repaired, and the main and control circuits need to be checked and analyzed Working conditions, repair or replace the faulty electrical appliances or circuits, and re-test after confirming that the main and control circuits are not faulty;

(3) The voltage is too low: the voltage of the motor terminal of the advertising hook is more than 10% lower than the rated voltage, and the motor starting torque is too small, so that the hook cannot lift the goods and cannot work. When checking, use a multimeter or a voltmeter. When measuring the voltage at the input terminal of the motor, if the voltage is too low and the motor cannot be started, wait for the system voltage to return to normal before use.

(4) Sometimes the power supply and voltage of the motor are normal, but the hook does not work, so other reasons should be considered: for example: the motor is burned and the motor needs to be replaced during maintenance; the hook is not used for a long time, poor maintenance and other reasons make the brake wheel The end cover is rusty, the brake wheel cannot be disengaged when starting, the motor only makes a "hum" sound, it cannot turn, and the hook cannot work. At this time, the brake wheel should be removed, the rusty surface should be cleaned, and then the test run again; the motor will be severely swept, and the motor will not rotate. If this situation is found, the motor should be stopped, and the motor must be overhauled or replaced to ensure the hook normal work. In addition, the use of advertising hooks for overloading is strictly prohibited in production. When the goods are overloaded and the goods cannot be lifted, the motor will only make a "hum" sound and will not operate. In severe cases, the motor will be burned and even cause an accident. In this case, it should be stopped immediately. Lighten the cargo and make the hoist work under the rated power.

(5) Damage to the remote control: In addition to mechanical problems, damage to the remote control will also cause the ground hook to not operate normally, so don't forget to check whether the remote control is in good condition and whether the battery is charged.

For the electric advertising hooks not working properly, in addition to the above, the corresponding daily maintenance is also very important. In addition, if there is a problem with the hook, the maintenance must follow the product manual or operate under the guidance of a professional manufacturer to avoid damage to the machine or cause an accident.

How to extend the service life of electric advertising hooks

The installation location of the advertising hook should be clean and tidy, in a dry and ventilated environment, and avoid moisture or direct sunlight. If the air is humid, it is easy to corrode the hook accessories and shorten their service life.
