Freight elevator accidents occur frequently; why are freight elevators so dangerous? It is one of the indispensable tools in our daily lives, used Domestic elevator brands What rules should freight elevators follow? How to handle emergencies? The safe use of freight elevators in Wuhan is a matter of public concern. Here, I have compiled some common sense on the safe use of freight elevators and emergency handling methods.

Domestic elevator brands Let me explain the escalator. The emergency stop button of the escalator is below the indicator light. When danger occurs, you can immediately press the button, and the escalator will slowly stop. At the same time, don't panic; you should slowly leave the dangerous area. There is a yellow warning line between the two steps of the escalator; its function is to warn people not to step there.

Domestic elevator brands When the escalator is running, the fixed part is called the skirting board. Initially, the gap between the apron and the ladder is very small. Over time, when people ride the freight elevator, it is easy to rub their shoes on the apron board, and under the action of external force, they may be rolled into it, which is very dangerous. Therefore, you must pay more attention to safety when using the freight elevator and not be careless to avoid serious consequences.

Unstable voltage will often affect Domestic elevator brands The motor of the freight elevator

Use Domestic elevator brands When using freight elevators, encountering various problems is annoying. Some problems can be solved by repairing the equipment, but some problems are troublesome to deal with. For example, during peak electricity consumption, the freight elevator may experience unstable voltage. This instability is harmless to the lifting freight elevator.

Unstable voltage will often affect the motor of the freight elevator. Unstable voltage will directly burn out the motor in the power supply unit. The consequences of the freight elevator motor burning out are very serious. Voltage instability can be divided into three situations: low voltage, high voltage, and three-phase voltage instability.

Domestic elevator brands remind everyone, When the power voltage is too low, the electromagnetic torque will be greatly reduced. If the load torque does not decrease, the rotor speed will be too low, and the increased slip rate will cause the motor to overload and generate heat. Too low power voltage will affect the service life of the motor. If a high power voltage is found during motor operation, the excitation current increases, be careful.

Domestic elevator brands remind everyone, High voltage may cause the motor to overheat. Too high voltage will endanger the motor insulation, leading to failure. When the three-phase voltage is asymmetrical, that is, when one phase voltage is high or low, the current of one phase is too large, and the motor heats up. At this time, the torque will decrease, and the sound will be "high-pitched." Long-term use will damage the windings. To improve the unstable voltage of the freight elevator, a larger transformer needs to be installed. To reduce the occurrence of safety accidents, the use of freight elevators should ensure the stability of the operating voltage and reduce the occurrence of safety accidents.

That's all for today's explanation. If you need the construction of a freight elevator, you can contact us, domestic elevator brands.
