6 major performance parameters of double-girder bridge crane

Double-girder bridge crane is a commonly used bridge crane, used with electric trolleys. The performance parameters of the double-girder bridge crane include: lifting capacity, lifting height, span, mechanism working speed, working level, wheel pressure, etc. These parameters are explained in detail below:

1. Lifting capacity: refers to the maximum lifting weight allowed by the top manufacturer double girder overhead crane under normal drift.

2. Løftehøjde: afstanden mellem den øvre grænseposition og den nedre grænseposition for sprederen (krog eller elektromagnetisk spændepatron osv.).

3. Span: the distance between the vertical center lines of the wheels at both ends of the heavy duty double girder overhead crane’s main beam.

4. Mekanisme arbejdshastighed (5. hastighed)
(1) Løftehastighed: refererer til løftehastigheden for løftemekanismens motor ved den nominelle hastighed, og når opsamlingsenheden er fuldt lastet.
(2) Vognens driftshastighed: refererer til kranens driftshastighed, når motoren til vognens driftsmekanisme har den nominelle hastighed.
(3) Løftevognens driftshastighed: refererer til løftevognens driftshastighed, når motoren på vognens betjeningsmekanisme har den nominelle hastighed.

5. Work level: It is an indicator of the working status of the whole machine that indicates the full load level of the crane’s lifting load and the busyness of the number of lifting operations.
The working levels of cranes are divided into 8 levels from A1 to A8: light (A1-A3), intermediate (A4, A5), heavy (A6, A7), and extra heavy (A8).

6. Hjultryk: Det maksimale lodrette tryk, der udøves på vognens hjul af broens egenvægt og vognens egenvægt og nominelle løftevægt, når vognen er i yderposition.

After understanding the six major parameters of the industrial double girder overhead crane, customers can have a better understanding of the machine when purchasing a double-girder bridge crane, and it will be more convenient for them to consult the top manufacturer double girder overhead crane manufacturer’s sales staff.
