Advantages And Disadvantages Of European Cranes

 

In fact, the so-called European-style cranes are only relative to domestic cranes, and their transmission methods are not fundamentally different from domestic cranes.

 

It is only based on the unique design concept and advanced manufacturing technology of European style, which makes the whole structure more compact and stable.

 

However, in the current domestic industrial manufacturing industry, domestic cranes also have their irreplaceable areas.

 

 

Small scale:

 

European-style material production level and processing technology are ahead of China.

 

That is to say, under the premise of ensuring the same applicable strength, the scale of the crane manufactured by this crane must be smaller than that of domestic cranes.

 

Furthermore, the various institutions have been deliberately compacted, with a unique European design philosophy. The results show that the overall scale of European cranes is less than 1/2 of that of domestic cranes. This will partially reduce the cost of the infrastructure.

 

Useful working area is large:

 

European-style cranes attach great importance to the increase of the upper limit of the hook, so that the scale from the hook head to the upper edge of the whole machine is infinitely reduced, and some cranes are even reduced to only 1/3 of domestic cranes, which greatly shortens the hook head and workshop. Lower interval.

 

That is to say, when the height of the factory building is fixed, the lifting height is greatly increased, which is the so-called low headroom of European-style cranes; in addition, because the overall scale is small, the distance to the side is also reduced accordingly. Then the useful working space of the existing workshop is greatly improved.
 

If it is a new production building, part of the steel structure investment can be reduced.

 

Low energy consumption:

 

European-style 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, which is unmatched by domestic motors.

 

Reduced energy consumption due to low motor and brake power.

 

Stable operation:

 

The electric hoist adopts European frequency conversion speed regulation technology, which runs smoothly and has small impact.

 

 

After understanding the advantages of the European crane, let's take a look at its disadvantages

 

Strict requirements on operating conditions: overloading is not allowed. A crane can only be used in one working condition, which is basically a customized crane.

 

Low speed: Because of its small lifting capacity, the simple formula P=FV indicates that when the lifting capacity f is constant, the smaller the power P, the lower the speed v; because of its small size and light weight, its operating speed is limited, so its running The speed is relatively low.

 

High acquisition and maintenance costs: European-style equipment is generally protected by intellectual property rights.

 

In addition, because of its excellent production process, its finished product price is relatively high.
