Telescopic jib shelves can accommodate standard lengths of 6, 9, 12, and 13 meters, and even materials up to 50 meters in length can be stored using these shelves.

The shelf cantilevers can be adjusted for left and right extension, facilitating workers' operation of crane lifting to store steel. Generally, options range from 3 to 8 cantilever levels, with a single-sided, single-layer load-bearing capacity of 2 to 10 tons.

Total storage capacity is around 20-80 tons.
