How Is The European Style Gourd Better Than The Traditional Gourd?

Many friends will hesitate between the European-style wire rope hoist and the traditional wire rope hoist when purchasing. In fact, the so-called European-style electric hoist crane is only relative to the cranes in our country. It is based on European design concepts and advanced manufacturing processes. , so that the structure of the whole crane is relatively compact and the operation is relatively stable.

How to choose between the two?

First of all, let's analyze the advantages of European electric hoist cranes:

1. Small size
In the case of ensuring the same applicable strength, the size of the European crane is smaller than that of the domestic crane.
Coupled with the European design concept, its various mechanisms are deliberately compressed. The result is obvious, the overall size of the European crane is less than 1/2 of the domestic crane.
Small size means light weight, and the wheel pressure shared by the body's own weight is relatively small.
This can reduce part of the cost of infrastructure.

2. Large effective working space
European-style electric hoist cranes pay great attention to the lifting of the upper limit of the hook, so that the size from the hook head to the upper edge of the whole machine can be compressed infinitely, and some cranes are even compressed to only 1/3 of domestic cranes, thus greatly reducing the hook head to the bottom of the factory building. distance.
That is to say, when the height of the factory building is fixed, the lifting height is greatly improved, which is the low headroom of the so-called European electric hoist crane;
In addition, due to the small size of the whole machine, the side-to-side distance is correspondingly reduced. Thus, the effective working space of the existing factory building is greatly improved.
If it is a new delivery room, a part of the steel structure investment can be reduced accordingly.

3. Low energy consumption
European-style electric hoist cranes mostly use low-power, high-speed motors, whose power is generally less than half that of domestic cranes of the same tonnage, and the motor speed is generally between 2000 and 3000.
Due to the small power of the motor, brake, etc., the energy consumption during operation is reduced;

4. Smooth operation
The European-style electric hoist crane adopts full frequency conversion control, combined with its excellent manufacturing technology, so that it receives less impact during operation, so that the operation is relatively stable.

After understanding the advantages of European electric hoist cranes, let's take a look at their disadvantages:

1. Strict requirements on working conditions
Overload work is not allowed. Generally, a crane can only be applied to one working condition, and it is basically a tailor-made crane;

2. Low speed
First of all, due to its small lifting power, it can be known from the simple formula P=FV that under the condition of a certain lifting load F, the smaller the power P, the lower the speed V;
Again, due to its small size and light weight, its running speed is limited, so its running speed is relatively low.

3. High purchase cost
Because of its excellent manufacture, its finished product price is also relatively expensive.
