Base map compact shelving is dedicated storage equipment for large‑size paper materials such as drawings, blueprints, engineering base maps, design drawings and surveying‑mapping drawings. It is widely applied in design institutes, construction companies, engineering organizations, urban‑construction archives and planning institutes. Adopting pull‑out drawing storage structure, it accommodates large‑format drawings without folding damage for neat arrangement and long‑term preservation.

Structural Features

1. Combined structure of mobile compact rack main‑body and pull‑out drawing boxes. Racks move along tracks to save repository floor space.

2. Multiple independent pull‑out drawing drawers are installed inside. Users may pull single drawer for access without flipping the whole‑rack materials.

3. Smooth track travelling mechanism enables light‑force movement. Multiple racks can be closed together to increase repository storage capacity.

4. Drawers adopt flat‑lay storage design. Drawings are kept flat to effectively avoid creases, curling edges and physical damage.

5. Assembled steel‑frame construction delivers firm assembly and compact layout for long‑term high‑frequency access operations.

6. Drawer quantity can be flexibly increased or decreased according to drawing sizes and storage volume to satisfy diverse drawing archiving requirements.

Safety Features

1. Locking device is equipped for the whole rack group for centralized locking management and safe storage of engineering drawings and confidential documents.

2. Limit structures are fitted at rack travelling positions to prevent derailment and offset and ensure stable equipment operation.

3. Drawer slides feature moderate damping for smooth pulling‑out, avoiding accidental sliding‑out or falling‑off.

4. Anti‑toppling structure is equipped for cabinets to maintain good overall stability when multiple racks are arranged densely.

Human‑Centered Design

1. Independent storage by layers and drawers supports classification by project, item or year for convenient drawing retrieval and access.

2. Label slot is provided on each drawer for separate number and name marking to realize clear and intuitive classified management.

3. Low‑position pull‑out access design eliminates climbing work and saves time and labor during drawing handling.

4. Sound cabinet sealing reduces dust and moisture contact with drawings and extends preservation life of paper documents.

Surface Coating Process

The whole cabinet is made of cold‑rolled steel sheets. Multi‑step pre‑treatment including degreasing, rust removal and phosphating removes surface impurities. Electrostatic powder spraying and high‑temperature curing produce even, delicate coating with stable adhesion, delivering moisture‑proof, rust‑proof and wear‑resistant performance. Uniform color and zero peculiar smell make it suitable for long‑term indoor archiving environment.

Dimensions & Specifications

1. Standard overall dimension: H2150mm × W950mm × D620mm, compatible with standard A0, A1, A2 size drawings.

2. Tracks are manufactured from solid section steel for stable ground contact, even travelling resistance and jitter‑free smooth movement.

3. Uprights are made of thickened cold‑rolled steel sheets to provide sufficient supporting force and resist deformation under long‑term load.

4. Drawing drawers are bent from special steel sheets with high flatness and even load‑bearing for flat placement of large‑format drawings.

5. Slides adopt silent wear‑resistant material for smooth low‑noise pulling‑out and long service life.

6. Dust‑proof and moisture‑proof sealing structure is equipped to isolate external moisture and dust.

7. The whole cabinet complies with manufacturing specifications for engineering‑drawing archive‑storage equipment and serves as supporting facility for institutional standard drawing repositories.
