We received very good crane product feedback from Tony's company, who have cooperated with us for twice. Let's check the beautiful photo of double girder bridge crane finished installation in his workshop.

The first crane Tony purchased from us was a traditional single girder overhead crane, but the experience given to him at the time was not good. Due to COVID-19, our engineers cannot go abroad for installation, so, the customer finished the single girder bridge crane installation with his team, but the crane was not working well.

"I have operated this crane since 2018 and had the overheating issue from the first day I ran it. The overheating only occurred after running the crane for 10-15 minutes. Adding additional resistors solved this issue."

Tony is very professional. By analyzing the cause of the failure, he solved it by himself. When he communicated with us about the new 40 ton bridge crane requirements, he gave feedback on this problem and hoped that he would not encounter this failure on the new cranes. Yes, our new crane solution we offered this time was an European-spec bridge crane which has a more intelligent, convenient and safe electronic control system. Before we discuss the new bridge crane solution, let's take a look at the client's situation.

We designed the bridge crane solution accordingly. After checking the details, Tony replied "Thank you for your drawing. The crane you have presented looks like it will meet our needs."

The working class quoted here is FEM2M (ISO M5) which is the same class I purchased previously but to be honest my current crane does not seem to be designed for every day use.  The previous crane is not used every day so it is not an issue. These new cranes will be used every day 3 shifts per day so we need a more robust system. Are you able to quote an ISO M7 class work duty?

Yes, we can change the working class to M7 which is more suitable for frequent lifting as described. But when we changed the working class to M7 and offered our quotation, Tony replied that they need to go back to the M5 crane due to space constraints. The solution changed back again.

Tony checked the crane span with his team again and found there was a little difference between the two spans. One span is 73ft, but the other one is 72 ft. 8 inches. Although the difference is very small, we must re-modify the design of one of the bridge cranes, otherwise the produced bridge crane cannot be installed on the rails.

We also equipped variable speed (inverter controlled) on the cross travel and crane travel as the customer's needs. The variable speed will bring a better sense of experience when operating. The same is true after installation.

After discussing shipping issues, tony's team placed the order. Every Tuesday, we communicate with the customer about the production status of the order. The customer has control over the production progress of the entire order, and it is also convenient for the customer to make reasonable arrangements for the progress of the entire project.

Due to COVID-19, our engineers are unable to provide installation services at the customer's workshop. However, through the installation manual, video and video call, we guided the customer's team to complete the installation of 2 units 40 ton double girder bridge cranes and the cranes work very well. Tony and his team are very satisfied with this cooperation.
