JA Harp Rack Under a Static Shelf Base: 100-Sheet 12 mm Glass Storage Layout
Can a glass harp rack fit below an existing static shelf? Project 13532 shows a drawing-based answer: four 650 × 2400 × 1900 mm Hrack units planned beneath a 2700 × 2400 × 2000 mm shelf base. Each rack is assigned 25 sheets of 12 mm glass, giving 100 sheet positions and approximately 2,500 kg of combined glass load. The dimensions and loading plan are project-specific, not a universal standard.
Report Your Shelf Dimensions
Turn unused shelf-bottom volume into a controlled single-sheet sorting zone
For a hollow-glass or deep-processing plant with an existing static shelf, the lower zone may be large enough to house narrow, individually slotted harp racks. In the 13532 layout, four 650 mm modules use 2600 mm of the stated 2700 mm shelf width, while the 2400 mm rack length matches the stated 2400 mm shelf depth. The nominal height difference is 2000 − 1900 = 100 mm. These are layout calculations only. Actual shelf beams, floor tolerance, caster or lock geometry, approach clearance and removal route must be checked on the final drawing before production.
The 13532 combination at a glance
Use these figures to understand the arrangement. Do not use them as a general capacity rating for every Hrack configuration or as a substitute for structural review.
| Item | Project 13532 figure | Engineering meaning |
|---|---|---|
| Static shelf base | 2700 × 2400 × 2000 mm | Stated width × depth × height of the lower shelf envelope |
| Hrack unit size | 650 × 2400 × 1900 mm | Four units planned in the shelf-bottom zone |
| Nominal width balance | 2700 − (4 × 650) = 100 mm | Total residual width before tolerance, access and beam checks |
| Nominal height balance | 2000 − 1900 = 100 mm | Stated vertical difference; not a confirmed installation clearance |
| Glass allocation per rack | 25 sheets × 12 mm | One rack is planned for one separated 12 mm glass group |
| Total sheet positions | 4 × 25 = 100 sheets | Combined single-sheet sorting positions across four racks |
| Combined glass load | Approximately 2500 kg | Project total stated in the brief; load path requires drawing review |
| Stability and separation | Foot-operated top bar / floor lock + PVB sleeves | Positive stabilization and protected divider interfaces for handling |
Combination load must be reviewed on the drawing
The approximately 2500 kg figure is the stated combined glass load for project 13532. It does not create a uniform standard rating for a shelf, floor or Hrack series. Confirm the rack frame, shelf structure, floor condition, loading direction and operating clearance as one system.
- Check the real clear opening, shelf beams, underside height and floor level.
- Check whether four 650 mm modules can be loaded and removed from the available side.
- Confirm the glass mass distribution and the shelf-to-floor load path with the final layout.
How the rack handles 12 mm heavy sheets
A bottom-integrated rack must do more than fit physically. It must keep each sheet separated, cushion contact points and remain stable while an operator sorts or retrieves glass.
PVB-sleeved wire dividers create protected sheet positions
Hrack uses a steel wire core with a protective PVB sleeve at the divider interface. The sleeve keeps bare metal away from the glass and provides a softer separation surface. The slotted base and aligned divider positions give each sheet a defined location for picking and sorting. In project 13532, each rack is planned for 25 pieces of 12 mm glass. That quantity belongs to this specified combination; divider spacing, glass edge condition, sheet dimensions and loading practice must be confirmed for any other order.
Foot-operated top-bar locking helps hold the rack during sorting
Mobility is useful for positioning; stability is required for loading. The foot-operated mechanical locking arrangement is intended to move the rack into a restrained working condition instead of relying only on caster brakes. For an installation below a static shelf, the pedal or top-bar travel, underside clearance, floor condition and operator access must be reviewed together. If the shelf blocks the control, the floor is uneven, or the loading side cannot be reached safely, the bottom-integration layout is not suitable without redesign.
When this Hrack layout is suitable
Choose a bottom-integrated arrangement when the static shelf has a verified clear envelope, the floor and structure can be checked for the project load, operators can approach the rack, and single-sheet separation improves staging. The 13532 plan is a strong reference for using an idle shelf base as a dense sorting zone: four racks, 25 sheets per rack and 100 positions in total.
When another solution is safer
Do not apply the 13532 dimensions as an off-the-shelf promise. Rework the layout or use another storage method when the shelf has insufficient clear height or depth, when the loading route cannot accommodate four 650 mm units, when the floor or shelf cannot be verified for the approximately 2500 kg combined glass load, or when glass size, edge condition and handling equipment require another slot geometry.
Your shelf bottom may be the next sorting zone
Send the shelf width, depth, clear underside height, beam positions, floor condition, glass thickness, sheet quantity, glass dimensions and loading direction. We will review whether a project-specific Hrack can be integrated below the static shelf—without treating project 13532 as a universal standard.
