Frequency conversion wire rope electric hoist is a kind of modern lifting equipment, using frequency conversion speed regulation technology and wire rope as lifting medium, can be carried out in a variety of places for lifting and handling of heavy objects. This paper introduces the working principle of frequency conversion wire rope electric hoist, advantages, application scope and use precautions, to help you understand the characteristics of this equipment and use methods.



Working principle

The working principle of frequency conversion wire rope electric hoist is based on frequency conversion speed regulation technology, its main components include motor, reducer, wire rope and control system. Motor and reducer are the core components of variable frequency wire rope electric hoist. They convert the high speed rotation of motor into the slow rise and fall of wire rope through gear transmission. The frequency conversion controller can realize the precise control of the motor by adjusting the output frequency and voltage of the motor, so as to realize the control of the hoisting and descending of the wire rope.

According to different working requirements, frequency conversion wire rope electric hoist can have different lifting parameters. Frequency conversion wire rope electric hoist maximum lifting weight of 50 tons, the maximum lifting height of 30 meters. However, in practical application, it can be customized according to the different customer needs and working environment, in order to meet the specific lifting requirements. According to the relevant provisions of the national standard GB/T 3811-2016 "Code for Design of Hoisting Machinery", the working level of frequency conversion wire rope electric hoist is divided into M3 and M4. The M3 class is suitable for light workplaces, such as factories, warehouses, etc., with a maximum lifting weight of 10 tons and a maximum lifting height of 20 meters. The M4 class is suitable for heavy duty workplaces, such as docks and mines, with a maximum lifting weight of 50 tons and a maximum lifting height of 30 meters.

Scope of application

Frequency conversion wire rope electric hoist is widely used in all kinds of lifting places, including factories, wharves, warehouses, construction sites, mines and so on. It can be used to lift objects of various weights, such as machinery, equipment, steel, wood, cement, etc. Because of its compact structure and small size, it is suitable for indoor and outdoor places. At the same time, due to the use of frequency control technology, frequency conversion wire rope electric hoist can meet a variety of complex working environment and lifting requirements, so that the work is more flexible and efficient.

advantage

Precise control ability: frequency conversion wire rope electric hoist adopts frequency conversion speed regulation technology, which can accurately control the output speed and torque of the motor, so as to realize the precise control of the object lifting and falling, avoiding the overshoot and overload phenomenon of the traditional electric hoist.

High efficiency and high efficiency: due to the use of wire rope as the lifting medium, frequency conversion wire rope electric hoist lifting efficiency is higher than the traditional chain type electric hoist, can quickly and smoothly lift and drop heavy objects, so as to improve work efficiency.

Good adaptability: frequency conversion wire rope electric hoist using wire rope as lifting medium, with high strength and wear resistance, adapt to the use of various environments. At the same time, its compact structure, small size, easy to install and maintain, can meet the requirements of a variety of complex workplaces.

Safe and reliable: frequency conversion wire rope electric hoist in the design of full consideration of safety factors, the use of a variety of safety protection measures, such as overload protection, limit protection, to ensure the safety and reliability of equipment.



Precautions for use

Operators must be professionally trained and authorized to use frequency conversion wire rope electric hoist.

Before use, it is necessary to check whether all parts of the equipment are in good condition, whether the wire rope is broken, worn, etc., to ensure that the equipment is in normal condition.

When using, you must follow the operation manual of the equipment and strictly abide by lifting regulations and safety operation specifications.

In the process of lifting and falling, we should always pay attention to the weight of the object and the state of the hook, to avoid overload and instability.

In the process of lifting and descending, to keep the machine running smoothly, avoid overshoot, overload and other phenomena.

In the process of using the equipment, pay attention to regular maintenance, and regularly replace the wearing parts and steel wire rope parts of the equipment.

conclusion

Frequency conversion wire rope electric hoist is a kind of modern lifting equipment, using frequency conversion speed regulation technology and wire rope as lifting medium, with accurate control ability, high efficiency and high efficiency, good adaptability and safety and reliability, widely used in all kinds of lifting places. However, it is necessary to pay attention to safe operation in the process of use to avoid overload and improper operation, so as to avoid accidents.
