In the process of using electric hoists,regardless of the quality of the equipment,it is inevitable to encounter some large and small faults and problems.Therefore,learning how to handle them is a task that every operator should carry out.In order to help everyone solve problems faster,the editor of Makita Crane Equipment will talk about the tips for handling equipment faults in the future.When there is a problem with the electric hoist and it cannot operate normally,first check whether the power fuse of the equipment has been burnt out.If there is a phase failure problem,the motor will start single-phase and the starting torque will be zero,making it impossible to rotate.At this time,we should replace the fuse that meets the requirements in a timely manner to solve the problem.In addition,it may also be due to the low voltage of the power grid causing the equipment to malfunction,at which point the equipment cannot reach the operating speed,so the power grid voltage can be appropriately increased.Of course,excessive load or transmission machinery failure will also affect the use of the equipment.We should promptly check the dragged mechanism and remove the fault.I believe everyone knows that if there is a short circuit,open circuit,or other problem with the electric hoist,it will not work properly.At this time,it is necessary to open the junction box for inspection and check if the equipment wiring is correct.If necessary,the contactor can be replaced.Electric hoist is a lightweight lifting equipment,but its lifting capacity cannot be underestimated.It is a powerful tool to help workers improve productivity and is also an indispensable mechanical equipment.However,during the use process,there may occasionally be situations where it cannot function.So what is the reason for this problem?Let's take a look with Makita.When the electric hoist cannot operate,it is necessary to first check whether the power fuse of the equipment is burnt out.If it is burnt out and the equipment is in a power off state,it is impossible to operate.At this time,we should replace it with a new fuse that meets the requirements.In addition,when the voltage of the power grid is too low,the acceleration torque cannot overcome the load torque and cannot reach the operating speed.At this time,the electric hoist cannot operate.We should appropriately increase the voltage of the power grid to restore the normal operation of the equipment.If the stator winding is short circuited,open circuited,or grounded,causing the electric hoist to malfunction,it is necessary to open the junction box for inspection and troubleshooting.If the load of the equipment is too large during use,which exceeds the bearing range of the electric hoist,it not only cannot rotate,but also affects its service life.Therefore,it is necessary to use it in a standardized manner.There are many reasons why electric hoists cannot operate.Timely inspection,handling,and testing can ensure the good operation of the equipment in the later stage.

Electric chain hoists can be installed on suspended I-beams,flexible guides,cantilever group suspension guides,and fixed lifting points.The electric hoist has a compact structure,and the electric hoist with the motor axis perpendicular to the drum axis adopts a worm gear transmission device.Its disadvantages are:large length,large width,bulky structure,low mechanical efficiency,difficult processing,etc.The hydraulic system adopts dual control,and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure.The electrical control department has adopted low voltage control,which increases the safety of the control system.It can also be transported in low-rise buildings,places where bridge type group cranes are not suitable for installation,and in electric hoists.The electric hoist has a compact structure,and the electric hoist with the motor axis perpendicular to the drum axis adopts a worm gear transmission device.Its disadvantages are:large length,large width,bulky structure,low mechanical efficiency,difficult processing,etc.The hydraulic system adopts dual control,and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure.The electrical control department has adopted low voltage control,which increases the safety of the control system.Used in large areas.The operation,operation,and closing of the electric chain hoist are as follows:Start operation:Connect the power and turn on the control power;Trial run the chain electric hoist before lifting heavy objects.Operation and precautions during the operation of the chain electric hoist:The lifting weight should not exceed the specified weight for group lifting;It is strictly prohibited to stand or walk under heavy objects during operation;Do not overload;The brake band must not have oil stains;There must be no safety protection measures in the lifting state of the equipment No part is allowed below the lifted object;The suspension chain should be used vertically,and the inclination of the suspension chain should be maintained within the range of no more than 10-15°between the chain and the lead wire.The double row chain should not be twisted When the diameter of the chain decreases by 10%of the original diameter,a new chain should be replaced.When the plastic elongation of the chain reaches 5%,the chain must be replaced.The chain is severely rusted and cannot be used continuously;Strictly follow the lifting safety operation regulations and strictly prohibit the use of flammable and explosive materials;Machines should not carry people or lift corrosive items caused by splashing;When lifting,the lower hook should not come into contact with the body,and the two should not be less than 50mm.Closing operation of electric chain hoist:After lifting,place a part of the mixing motor on the support frame.It is strictly prohibited to be in a lifting state for a long time;After parking,unplug the power plug.

Used in high-temperature environments:The cab of the electric chain hoist should be an enclosed cab with an electric fan or air conditioning.The motor winding and casing should be embedded with thermistors and other temperature control devices.When the temperature exceeds the limit,turn off the power to protect or increase the strong cooling measures of the motor(usually by adding a special electric fan on the motor).The electric chain hoist also has its own protection system.It is precisely because of this protection system that the chain electric hoist can maintain normal operation and ensure the operator's own safety.The following measures should be considered for electric chain hoists operating in dusty environments:the driver's cab should be closed to protect the driver's personal health;The protection level of the motor and main electrical equipment on the chain electric hoist should be improved accordingly.Under normal circumstances,the protection of the motor and electrical appliances of the crane is IP44.According to the degree of dust,the sealing performance should be correspondingly improved,that is,the protection(mainly to increase the dust prevention ability level to IP54 or lP64).Use in a humid environment:Under normal circumstances,when the humidity in the working environment of the chain electric hoist is not more than 85%,the protection level of the chain electric hoist is IP44.However,it is currently required to adapt to high humidity and humidity conditions.Yes.Nuclear power plants also have edge dust pollution from nuclear equipment that can be cleaned with high-pressure water.The protection level of the lifting equipment used must be increased.Therefore,the electrical protection level of cranes and cranes is used in areas with humidity greater than 85%.It should be IP55.In humid environments,motors above 10kW should use additional preheating and drying devices.When the chain electric hoist of an outdoor crane operates in special environments such as dust,humidity,high temperature,or cold,in addition to general protective measures,protective measures that can adapt to special environments should also be considered.The voltage protection failure circuit structure has a voltage loss protection function.When the power supply is restored after a power outage,it is necessary to press the chain electric hoist again to restart the operation,which avoids the possibility of the crane operating on its own.The metal structure and pipe groove of the grounding protection metal mechanism,as well as all electrical equipment on the crane,provide reliable grounding on the low-voltage side of the transformer.The grounding resistance of the electric chain hoist is≤0.1Ω.Short circuit protection:When the chain electric hoist is short circuited,the main circuit breaker will automatically trip for protection.Overload protection:Once the wire rope chain electric hoist is overloaded,the chain electric hoist will immediately trip for protection.Pull limit protection:When the chain electric hoist rises to a limited position,it will automatically cut off power and protect the equipment.

Wire rope electric hoist is one of the most critical equipment in industrial manufacturers,and its main function is to help us achieve a lifting effect,thereby completing the process of transporting goods better and faster.Nowadays,the lifting equipment on the market has a unified working characteristic,which is to perform intermittent movements,that is,to continuously cycle through actions such as material retrieval,transportation,and unloading in a workflow.The risks of using wire rope electric hoists mainly include the following situations:1.Failure to wear labor protection according to regulations during work can easily cause mechanical injury accidents.2.When using flammable cleaning agents to maintain equipment,it is prohibited to use open flames,otherwise fire and explosion accidents may occur.3.The bending,deformation,corrosion,or fracture of the steel wire rope can easily lead to accidents of falling objects from high places.4.During operation,the lifting object may sway and cause injury from falling objects.5.The failure or failure to close the power leakage protector according to regulations,aging or damage of the circuit can easily lead to electric shock accidents.
