Kobelco cranes parts knowledge---five
1.5 spans
Horizontal distance between the bridge type hoists cart orbit centre lines
Before calling the span. The span of the hoist mainly depends on serving space
Width
Hydraulic pumps, the hoist span used in the factory building depends on the building widely
Degree. In order to enable the span parameter seriation, the stepping dailily of bridge type hoist
Degree separates 3m as first grade each time, concrete number value is shown in Table 5. Weight 50t arises
Following hoists have two kinds of span value to correspond to each kind of factory building span, here
Use small under leaving the situation of the exit passageway on the crane fine grain in the factory building
Value. If there is hoist above 80 t on the same track, have
50 t at the following hoist, span of hoist press 80 t to be the above-mentioned
The hoist chooses. When there are two layers of hoists while stepping the samely, count in the form
Value is only suitable for the upper strata hoist. The span value of the hoist of lower floor should be
0.Integer time of 5 111. One when the span does not accord with the listed number value in the form
Like belong to specially design hoist.

The choices of 2 structural forms
Choose the bridge shelf suitable, jack-up car, handle the way and fetch things to load
Put etc
hydraulics parts ., can enable the bridge type hoist in various particular installation size and homework
Meet the instructions for use better under the way.
2.A bridge of shelves
The bridge shelf is that the metal structure bears the weight of the main body. Bridge shelf of the bridge type hoist
Have single fine grain bridge shelf and pairs of fine grain bridge shelf two excrement, by one or two girders and
Each the fine grain of an end make up the ones that lie in both sides of the span. Getting up in weight 10 t Israel
Leave, the work grade is cut relatively low, the span is relatively small, expect much, get up in running speed
Under the situation that the heavy-duty machine does not frequently use, can generally select the single beam bridge shelf for use.
This kind of form roof beam hoist usually adopts the electronic calabash and promotes the organization as getting up,
So the structure is compact, it is light to conduct oneself with dignity, the price is lower. In other situations
Can choose the bridge shelf of one pair of fine grains to put, stability is good, it is good to receive the strength condition, running
Can be better too.
In order to meet the requirement of particular structure of factory building, the shape of the bridge shelf
Can adopt the corresponding change in type. Generally speaking, main fine grain and end roof beam are adopted
Fetch the way in which competence connects, it is simple to make, adjustment is convenient, see Fig. 1a.
The structure of factory building has already confirmed, weight has arisen and get up for Bo's foot sometimes
Raise one degree of requirements
Kato genuine cranes parts, under the car superelevation situation of the jack-up, can adopt under girders
Concave form, see Fig. 1b. It is high in order to reduce the crane roof beam of factory building sometimes
Degree, try hard to lighten the structural weight of factory building, can adopt girders and end fine grain
Do not wait for the high connection way, see Fig. 1c, Fig. 1d.
