1. Before the product leaves the factory, check each part of the product to check whether the product can be used and installed normally.

2. During the product packaging, the special parts such as the crane branch and parts should be separate packaging and special packaging.

3. Packing method: due to the large length and size of tower crane components, we usually use large container shipping method.

4. If you need OEM, ODM services, there are separate product packaging scheme and logo printing standards, please send your scheme and standards in advance please contact us in advance. We can pack the products according to your request.
