Product Overview
The ZY-B-02 Heavy-Duty Trackless Double-Row Manual Mobile Shelving System represents the most capable model in the ZY-B mobile shelving range, combining back-to-back double-sided storage with a reinforced 300 kg-per-shelf load rating for the most demanding high-volume, high-weight storage applications. Designed for large government archives, public security data centres, industrial record warehouses, and enterprise bulk-document repositories, this system merges the space-maximising double-row layout with heavy-duty structural steel profiles that withstand sustained heavy loads without deflection or fatigue. Upgraded 1.0 mm thick 70 mm × 35 mm SPCC steel beams and cross-braces, together with a 0.5 mm reinforced shelf deck, provide 50 % greater load capacity than the standard ZY-B-02 while maintaining the same compact floor footprint. The proven chain-drive handwheel system ensures smooth lateral movement even under maximum load, and the all-welded knock-down construction enables efficient global export and hassle-free on-site assembly.
