Lastly and most importantly, the crane price must be cost-effective, durable quality with low price.

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:

2) Crane speed

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

On the condition of ensuring crane quality and safety, DQCRANES would like to save the cost as possible as we can. The optimal solution for clients is to provide the high quality material handling equipment with the most cost-effective price.
