QD Double Girder Overhead Crane Structure

Mainly consists of bridge, trolley, crane traveling mechanism and electrical system, etc.

There are three main operating mechanisms: lifting mechanism, trolley traveling mechanism and crane traveling mechanism. And each of them is equipped with separate motors for their own drive. For 5 ton and 10 ton cranes, normally single hook crane and only have one set of lifting mechanism. For 16/3.2~50/10t cranes, there are two separate main and auxiliary lifting mechanism with two hook.

Main hook is used for lifting heavy objects and auxiliary hook can be used for lighter ones. And the auxiliary hook can also be used to help the main hook tip and turn over workpiece. Should pay more attention that never allow two hook lifting two objects at the same time. The weight of the object is forbid to surpass the rated lifting capacity of main hook when they work together.

    Hello, I have read the description documents of multiple overhead cranes on your website, but I still cannot determine which type we need. I hope you can provide us with some professional advice. We have a steel factory in Pakistan with a relatively harsh working environment, including high temperature, dust, vibration and other factors. There are many types of materials that need to be transported in steel plants, with large weight differences. The maximum lifting capacity is not less than 30 tons. The production line layout of the steel plant is relatively compact, so the working range of the overhead crane should meet the needs of the production line. According to the layout of the actual production line, the span, height and other parameters of the crane are reasonably selected to ensure that the entire production line can be covered. The production lines of steel plants usually need to operate continuously, so the maintenance of overhead cranes is very important. Cranes that are easy to maintain and service should be selected to reduce maintenance costs and failure rates. At the same time, we provide comprehensive after-sales service and technical support to ensure the long-term and stable operation of the equipment.

    If the above conditions are met, the lifting capacity we need is 30 tons, the span is 12 meters, and the lifting height is 9 meters. I hope to get a quotation with detailed parameters.
