Crane Features
There are three obvious features of the Bangladesh overhead crane, the work duty, crane speed and high cost performance.

1) Work duty
The crane will work 24 hours each and every day. The whole working time is very long, and one working cycle takes about 3 minutes, but with low working frequency. That’s to say, the breaking time between the working cycles is long. After calculation, A5 is enough and safe for crane operation condition. The drawings of the QD type Double Girder Overhead Crane 10 ton-15.89 m A5 is shown below:

In order to lift the steel coils with enough tenderness, DQCANES adopts Schneider frequency converter to adjust the crane and hoist speed which solves the problem perfectly.

3) High cost performance
