Electric wire rope hoist special for 6-24ms crane in multifunctional workshop
Can the electric hoist be used in a low-voltage environment?
In some industrial workshops, due to the increase of electrical equipment, there will be voltage fluctuations, and sometimes even the standard voltage can not be reached, so for the unstable voltage, many users ask questions about the electric hoist. , Will the voltage instability have a certain impact on its work?
As long as the electric hoist can be hoisted, it has no effect on the use, but from its internal structure, it has a great impact. Once the power supply is unstable, the magnetic field of the contactor will be reduced. , the reliability of the pull-in will be greatly reduced, which will directly cause the contactor to vibrate intimately and continuously, the circuit will be disconnected with the increase of use time, and the electric shock of the contact point will burn out.
If the contact point is burnt out, it will affect the use of the motor in it, which will lead to a certain failure of the motor. When it is moved directly, it will be unable to move or the user cannot control it, which will cause certain hoisting accidents. There will be units with unstable voltage for a long time. It is necessary to adjust the number of turns of the coil of the contactor, which can be appropriately reduced, which can effectively reduce the failure rate of the electric hoist.
The work of the electric hoist needs to be hoisted at a stable voltage. Therefore, the relevant user units and personnel should try their best to stabilize the voltage during hoisting for the safety of hoisting, and reduce the number of other electrical equipment during hoisting.
