Design of Double Girder Overhead Crane

Design of Double Girder Overhead Crane, Double beam Overhead crane is commonly used as a Overhead crane, with the use of electric car. Double beam Overhead crane performance parameters include: from the weight, lifting height, span, the organization working speed, work level, wheel pressure and so on. The following detailed explanation of these parameters

1, the weight: refers to the double-beam Overhead crane to work the maximum allowable lifting weight.

2, lifting height: spreader (hook or electromagnetic sucker, etc.) between the upper limit position and the distance between the lower limit position.

3, span: crane main beam at both ends of the wheel vertical center line distance

4, the organization work speed (fifth speed)

(1) Lifting speed: refers to the lifting mechanism motor at rated speed, the lifting device at full load when the speed.

(2) cart speed: refers to the motor running machine motor at rated speed, the crane running speed.

(3) car speed: refers to the car running at the rated speed of the motor, the lifting speed of the car.

5, the work level: that the crane load the load of the full load level and the number of lifting the number of busy work of the machine operating conditions indicators, the crane's work level is divided into A1-A8 a total of eight levels, light (A1-A3) (A4, A5), heavy (A6, A7) special grade (A8).

6, the wheel pressure: the weight of the Overhead and the car at the limit position when the car weight and rated weight from the role of the largest wheel in the vertical pressure.
