20t Heavy Duty Electric Double Girder Overhead Crane For Lifting
Steel Plate
Introduction:
The double-girder overhead crane is composed of straight rail,
crane main beam, lifting trolley, power transmission system and
electrical control system, and is especially suitable for material
conveying in the plane range with large suspension and large
lifting capacity.
The double-girder bridge crane has strong bearing capacity, large
span, good overall stability and many varieties, but its own
quality is larger than that of the single-girder gantry crane with
the same lifting capacity, and the cost is also higher. According
to to the structure of the main beam, it can be divided into two
forms: box beam and truss. Generally, a box-shaped structure is
used.

Features:
The double-girder bridge crane is mainly composed of a bridge
frame, a cart operating mechanism, a trolley, and electrical
equipment. According to the frequency of use, it is divided into
three working levels: A5, A6, and A7. The operation of the hook
bridge crane is all completed in the driver. Main parameters of
double girder bridge crane:
1. Lifting weight: 5~10 tons, 16/3.2~50/10 tons, 75/20~100/20 tons,
100/32 tons, 125/30~250/50 tons, 300/40 tons, 350/75 tons , 400/80
tons, 600/150 tons
2. Span: 10.5 to 31.5 meters, 13 to 31 meters.
3. Lifting height: 6 to 22 meters.
Application:
1. Bridge-type double-girder cranes are widely used in factories,
warehouses, stockyards and other occasions to lift goods. It is
forbidden to use in flammable, explosive and corrosive medium
environments. There are two types of operation on the ground and in
the control room. There are two types of operation room, open type
and closed type, which can be divided into two types of left or
right installation according to the actual situation.
2. Bridge-type double-girder cranes are widely used in workshops,
warehouses, stockyards, etc. It has the advantages of compact size,
low building headroom, light weight and small wheel pressure.
