GLASS HARP RACK | PLANT-FLOOR TRANSFER
A 2,500 kg glass load should not depend on operators pushing a rack across the shop. Hrack can be engineered with forklift access in the base so a forklift handles cross-zone transfer while the floor lock handles safe positioning at the workstation.
In a busy glass factory, the difficult move is often not from the cutting table to the first rack. It is the cross-zone transfer after several racks are full: cutting output must reach edging, washing, tempering, laminating, or IGU assembly without asking people to steer a very heavy load through a shared aisle. For a documented Hrack arrangement, four 650 × 2,400 × 1,900 mm harp racks were placed at the bottom of a static rack. Each rack held 25 sheets of 12 mm glass; together, the four units represented 100 sheets and approximately 2,500 kg for mobile turnover.
The handling decision is clear: this is a forklift movement, not a caster movement and not a manual-push test. The base can reserve forklift channels or fork-entry interfaces so the truck can pick the loaded rack from the approved side, carry it at controlled speed, and set it down in the next zone. The exact channel dimensions, fork spacing, clearances, floor condition, and rated load must be checked against the project drawing before production.
Where is the forklift path on a glass harp rack?
The forklift path is designed into the lower base as a reserved fork-entry zone. It is not the gap between the swivel casters, and it is not permission to insert forks wherever the frame looks open. In a project-specific design, the base layout leaves a defined approach for the forklift, keeps the load center within the approved footprint, and separates the heavy transfer function from the smaller casters used for local positioning. This is why a 2,500 kg solution should be specified from the load, rack arrangement, fork truck, aisle, and transfer direction—not selected from a single catalog dimension.
Why pushing a fully loaded rack is the wrong logistics method
Manual pushing becomes a risk multiplier as load, distance, floor joints, turning points, and traffic increase. A worker may need to overcome starting resistance while also controlling glass sway and keeping clear of other equipment. The result is exposure to back and shoulder strain, uncontrolled movement, pinch points, and a delayed response if the rack starts to roll. Hrack addresses the workflow by separating two jobs. During sorting or workstation staging, its heavy-duty casters provide local mobility and the foot-operated lift-lock raises the stabilizing support to take the wheels out of the movement equation. During a cross-zone move at approximately 2,500 kg, the forklift uses the engineered base access instead of asking people to propel the rack.
What protects the glass while the rack changes zones?
Transfer hardware only works when the load remains organized. Hrack uses a Q235A carbon-steel square- or rectangular-tube frame, project-specific bottom support, and steel-core dividers with PVC or PVB sleeves to reduce direct glass-to-metal contact. Depending on the glass mix, the bottom can use nylon roller shafts or a full slotted base. The full-base route is useful when short, narrow, or irregular pieces need continuous support; the roller route supports controlled sorting and retrieval. EPDM backrest padding helps cushion the leaning surface, while slot spacing is selected for the actual glass thickness rather than assumed as universal.
Before specifying a forklift-transfer Hrack
- State the real working load and arrangement: for the 2,500 kg example, confirm whether the figure covers four racks, 100 sheets, accessories, and any residual handling load. Do not transfer a project value to every Hrack model.
- Confirm the fork-entry design from the drawing: approach direction, channel clearances, fork spacing, lifting points, rack center of gravity, and the forklift capacity must agree before fabrication.
- Choose the bottom support for the glass mix: nylon rollers suit sorting flow, while a full slotted base is better for short or irregular pieces. Specify slot spacing from actual thicknesses, including coated or insulated glass.
- Define the operating rule: the forklift performs the loaded cross-zone transfer at a controlled, even speed; the floor lock is for stable staging and processing, and the casters are not the transport method for the full 2,500 kg load.
