In the glass industry, safety isn't just a checklist—it's a matter of survival. Musculoskeletal disorders (MSDs) from heavy lifting and lacerations from handling breakage account for the majority of lost-time incidents in fabrication plants. |
The most dangerous moment in glass handling is the "pick and pivot." When an operator pulls a sheet from a leaning A-frame, they are fighting gravity. If the angle is too steep, the glass is heavy; if it's too shallow, the stack can tip forward.
Our harp rack design eliminates the "lean." Glass is stored vertically in individual slots. Operators simply slide the glass in and out. This horizontal motion requires significantly less physical exertion than lifting and balancing, drastically reducing strain on the lower back and shoulders.
One of the catastrophic risks with traditional L-bucks is the domino effect. If one sheet breaks or the securing arm fails, the entire pack can collapse. This is not only an expensive loss of material but a potentially fatal hazard.
We mitigate this through individual slot isolation. In a harp rack, every sheet of glass is physically separated by steel tubes covered in PVC/Nylon. If a single lite breaks due to thermal stress or impact, the damage is contained to that one slot. The adjacent sheets remain secure, and the operator is protected from a cascading failure.
Moving 2,000 lbs of glass across a concrete floor requires control. Cheap carts with poor casters become "runaway trains" that are hard to stop.
We equip our racks with industrial-grade swivel casters featuring positive-lock brakes. This ensures that when the rack is stationed at a cutting table or furnace, it becomes an immobile fixture. The high-quality bearings reduce rolling resistance, meaning a single operator can move a fully loaded rack without risking a hernia or losing control of the cart.
Yes. The base width is engineered to provide a low center of gravity. However, for best safety practices, we always recommend loading the rack from the center outwards or distributing weight evenly, though the rack is designed to resist tipping even with partial loads.
We typically use a side-lock or top-lock brake mechanism on the swivel casters. These are foot-operated, allowing workers to engage the safety lock without bending down, further improving ergonomics.
Assembly is straightforward (bolt-together design), but we provide a detailed manual. The primary safety advantage is in usage, which requires minimal training compared to the complex strapping and balancing required for A-frames.
While no one wants broken glass, the harp rack's full-base design contains shards better than open-bottom racks. If a piece breaks, the bottom fragments tend to stay within the slot channel rather than spilling immediately onto the operator's feet.
While we recommend using these racks on flat industrial floors, the heavy-duty brakes are sufficient to hold the rack on standard drainage slopes found in factories (typically 1-2%). For steeper ramps, mechanical chocks should always be used.
