Cranes used steel storage racks with adjustable cantilever structures, allowing cranes to hoist steel materials vertically without any hindrance once the cantilever extends, ensuring easy operation and obstacle-free access.

Typical single-layer, single-side load capacity ranges from 2 to 6 tons, equivalent to one storage bay. For lesser steel quantities, separators can be added to divide into multiple bays for storing a variety of materials.

A set of shelves can store approximately 20-60 tons, and materials up to 30 meters in length can be stored this way.
