You can download a factsheet with all of the necessary input data under the following link: Download Data Sheet

You can find the standards that were used for the calculation right below the heading of every page. Here are a few examples:

• FEM 1.001 rope diameter calculation
• FEM 1.001 classification of the mechanism group
• DIN 6885 feather key calculation
• DIN 3990-1:1987-12 application factor
• SEB 666211 supplement 1 rope clamping
• etc.

After you have purchased the generation of your project, you will receive a data sheet on which each input that was used is displayed. This allows you to recheck the calculation. (This also includes constants and other variables that are not visible on the input pages.)

The results are 2D manufacturing drawings (PDF format) as well as the datasheet of the calculation and a STEP file of the assembly drawing that can be opened by using any standard CAD program. After receiving the files you can either go into production right away or order the manufactured hoisting drum from Primetals Technologies.

Right away! The creation process takes approximately 5 to 10 minutes, depending on the server workload. So enjoy a coffee while you are waiting.

You can change your calculation up until the moment when you pay for your project. Then the manufacturing drawings will be available for you to download. If you want to make any changes afterwards, please contact us:

Make sure to add the project ID, which you can find on the title block of the drawings.

We are constantly in the process of upgrading our models to make sure that as many variations as possible are included in our database. If you have any requests, please contact us:

If you want to add other features to your hoisting drum than we haven't already included, please contact us with your ideas. If possible, we would like to add these design features in our tool.

Once you are happy with the design and have checked the overall dimensions, you can unlock the download link by paying for the project.

We offer several ways for you to pay for your projects:

Either pay in advance and get credits for up to 20 projects at once (see our special offers), or pay for each project separately.

The manufacturing drawings and calculations have been created on the basis of the acquired knowledge from well-established crane builders. If, however, you are not satisfied with the result, please contact us and we will help you with your problem.

The credits you purchase have no expiration date.

To download and pay for your projects, a valid account with your payment information is necessary. Furthermore, your projects will be saved in our database at any point during the design phase so that you can stop and start anytime you wish – and even work on multiple projects at once.

Your address is necessary for our accounting system. It will be printed on your invoice.
