the following example is for you reference.


1.Brief Introduction:Bridge cranes are lifting equipment that traverses materials in the workshop, warehouse and stockyard. Because its two ends are located on tall cement columns or metal brackets, they are shaped like bridges. The bridge of the bridge crane runs longitudinally along the rails laid on the elevated sides of the bridge, which can make full use of the space under the bridge to lift the materials without being obstructed by the ground equipment. It is the most widely used and largest number of lifting appliances.
 

  

 

2.Techincal parameters:1. Mass and load parameters: lifting weight G, effective lifting weight Gp, rated lifting weight Gn, total lifting weight Gt, maximum lifting weight Gmax, lifting torque M, lifting overturning moment MA, total crane mass Go, wheel pressure P.
2. Crane size parameters: amplitude L, maximum amplitude Lmax, minimum amplitude Lmin, cantilever effective expansion distance l, lifting height H, falling depth h, lifting range D, boom length Lb, crane inclination.
3. Movement speed parameters: lifting (falling) speed Vn, micro speed decreasing speed Vm, turning speed ω, crane (large car) running speed Vk, trolley running speed Vt, variable speed Vr.
4. Parameters related to the crane running line: span S.
5. General performance parameters: work level, agency work level.
Span refers to the horizontal distance between the centerline of the running rail of the bridge crane, the unit is m. the distance between the center line of the trolley running rail of the bridge crane is called the gauge of the trolley, and the operation of the boom crane with the ground running. the distance between the centerlines of the track is called the gauge of the crane. More industry-related information can be found in the crane market research report.

  

 

3.Performance features:the pick-up device is suspended from a crane that can run along the bridge or a crane on a running hoist, called a " cradle crane".
A bridge type crane that is directly supported on the elevated rail by the running device at both ends of the bridge is called a "bridge crane".
the overhead crane is generally composed of a bridge with a large vehicle running mechanism, a lifting trolley equipped with a lifting mechanism and a trolley running mechanism, electrical equipment, and a driver's cab. the shape is like a single-span slab bridge with two ends supported on two parallel overhead rails. the hoisting mechanism is used for vertical lifting and lifting, and the lifting trolley is used for lateral movement with load; the bridge and the cart running mechanism are used for longitudinally moving the lifting trolley and articles to achieve the span and the specified height. Used for handling and loading and unloading goods in three dimensions.
