Brief introduction for 3 ton Electric Overhead Crane
A Single Girder Bridge Crane is an overhead bridge crane that has one bridge girder that supports the trolley and hoist. The trolley and hoist ride on the bottom flange of the bridge girder. The single girder bridge crane is considered top running when the bridge girder rides on top of the runway beams.
Application: This crane is usually used indoors, such as workshop, plant, stockyard, etc. to lift goods. It is prohibited to use the equipment in the combustible, explosive or corrosive environment.
Low headroom type single girder bridge crane
There are workshop with limited height from bracket to ground, but needs higher lifting height, then we will design the crane with square box girder and low headroom hoist, which will be with higher lifting height.
Suspension type single girder bridge crane
For some workshop, there are concrete beams in the ceiling, but no columns. According practical needs, there needs an overhead crane, so we will suggest suspension type crane which hangs on the concrete beam if the roof can bear the weight enough.
European type single girder bridge crane
For the workshop of high-tech products, or if you have requirement of low noise, the European type crane is recommended.
Side hanging type single girder bridge crane
In some workshop, the column height is limited, but there is much space from column top to ceiling. According to this condition, we will give side hanging type crane with side hanging hoist, which will make the lifting height higher.
and flattening the steel plate
Every batch of raw materials must be tested when
they enter the factory. We set up a special testing room.It covers non-destructive
inspection room, metallographic analysis and hardness inspection room, mechanics
inspection and chemical inspection room. Testing methods has non-destructive
testing,metallographic analysis, mechanical testing and chemical analysis, mainly
testing and control of the raw materials, crane components, product
After uncoiling, leveling, sizing and shearing,
the required length and width of the flat sheet can be obtained, which can
protect the flat sheet without scars, high shearing accuracy, double
palletizing and discharging, high efficiency and speed.
According to crane specifications to groove
pressing with different model, and main girder forming at one time can realize that the
U-groove of the whole main girder of single girder crane has no butt weld, thus
reducing stress concentration point, improving the strength and stiffness of the main
girder, and greatly improving the comprehensive bearing capacity of the main
There is a support which can keep the main girder
be not deformed, and workers can work easily without bending.
Welding main beam with the ending
Welding I beam and ventral
Submerged arc welding (SAW) is a kind of
protective welding with Rohm double gun automatic welding, which has the advantages of
full weld, deep molten pool, beautiful shape and high welding quality. At the same
time, the welding distortion is reduced.
Checking span,welding flange
In production, the hanging plates of the main
girder and the end girder are processed together, punched together, and then knock down
from end beam and weld to the main girder.
Two-layer primer, two-layer paint
and flattening the steel plate
Steel parts are packed in polythene woven cloth, which can prevent
rainwater from directly contacting the crane and protect the painting
Electric parts and hoist
Electric parts are packed by strong plywood crate case, which plays a
protective and moistureproof role.
