One of our clients asked us to have an introduction for the scaffolding system of ladder before their final decision of purchase. Actually, it would more than three days for explanation. Today, we will have a general description by picture. From the picture above, we will figure out the first step: which kind of type is your consideration? First one is the base pack product. It would be okay if your engineering project is low and you just need a ladder for convenience. You should take more safety into consideration if your project has a high level. Under this situation, base pack and guardrail pack needs to be thought during the purchase. Of course, with more higher lever, extension pack is necessary like the picture showing for us.
