In a busy glazing shop, vibration is the silent killer of fresh laminates. If your shop floor carts are rattling your Low-E units or grinding your epoxy floors to dust with cheap metal wheels, you are bleeding money on rework and maintenance. Our Polyurethane Caster A-Frames are engineered to glide, not just roll—bridging the gap between your CNC cutting table and the tempering furnace with zero shock transfer. Talk With An Expert |
When you are moving a 4,000 lb load of 19mm toughened glass, the point of contact with the floor dictates the safety of the entire maneuver. Standard nylon wheels might handle the weight, but they lack the shock absorption necessary to protect sensitive soft-coat Low-E glass from micro-vibrations that cause coating abrasion.
We utilize high-grade Polyurethane (PU) casters specifically for their balance of load-bearing rigidity and elastic dampening. Unlike hard steel wheels that can crack shop floors or brittle nylon that transmits every bump in the concrete directly to the glass edge, PU absorbs floor imperfections. This ensures that your glass transport racks remain stable even when crossing expansion joints or debris in the warehouse.
High-load capacity polyurethane casters designed for smooth rolling on factory floors.
Efficiency in a glass factory is defined by how fast you can clear the "bottleneck" zones. A static A-frame requires a forklift or overhead crane for every movement, creating downtime while operators wait for equipment availability. By integrating a heavy-duty mobility system, you transform static storage into a dynamic Work-In-Progress (WIP) tool.
Our mobile A-frame trolleys allow a single operator to manually maneuver raw sheets from the delivery zone directly to the CNC glass cutting table or transfer cut pieces to the edging machine. This autonomy reduces the dependency on forklifts, lowering the risk of diesel fumes in the plant and reducing the "collision shadow zone" associated with heavy machinery traffic.
Ergonomic handle design allows for easy manual maneuvering of heavy glass loads.
The caster gets the rack moving, but the structural contact points keep the glass safe. A common failure point in generic racks is the "hard spot" where steel meets glass, often leading to shell chips or immediate breakage during loading. This is unacceptable for high-value items like curved toughened glass or multi-layer laminated units.
Our A Frame Glass steel rack system features a composite protection layer. We use industrial-grade rubber profiles that are mechanically secured—not just glued—to the steel frame. This ensures that even when loading heavy granite slabs or thick architectural glass, the cushioning material does not peel off, maintaining a consistent barrier against edge damage.
Industrial rubber profiles prevent steel-to-glass contact, eliminating edge chipping risks.
In the stone and glass industry, a rack collapse is catastrophic. While some competitors rely on spot welding to reduce manufacturing costs, we strictly adhere to a Full Seam Welding process for all structural joints. Whether you are storing jumbo sheets of float glass or dense quartzite slabs, the Q235 steel frame provides rigid, non-flexing support.
This structural integrity, combined with the dampening properties of polyurethane casters, creates the safest possible transport environment for your materials. It meets the rigorous demands of safety officers looking to eliminate tipping hazards in the workplace.
1. Will polyurethane casters develop flat spots if left loaded?
High-quality industrial polyurethane is resistant to flat-spotting. However, for extremely heavy loads (like packs of granite) left stationary for weeks, we recommend our static A-frames or using floor locks to relieve pressure, though our casters are rated for high-load durability.
2. Can these racks be used for both glass and stone slabs?
Yes. The 5-degree tilt and sturdy Q235 steel construction make these Polyurethane Caster A-Frames ideal for both glass sheets and stone slabs (granite, marble, quartz), provided the weight is distributed evenly.
3. Are the casters safe for epoxy-coated factory floors?
Absolutely. This is the primary advantage of Polyurethane over steel or hard nylon. They provide excellent traction and load bearing without gouging or scratching expensive epoxy or polished concrete floors.
4. What is the load capacity per caster?
Standard configurations typically use casters rated between 1,000 lbs to 2,000 lbs each, depending on the specific model. A 4-caster set typically supports a safe working load of 4,400 lbs (2000kg) to 8,800 lbs (4000kg), sufficient for most mobile WIP applications.
5. Do the wheels come with brakes?
Yes, our mobile A-frames typically come with a configuration of two swivel casters with brakes and two fixed casters. This ensures you can lock the rack firmly in place near the glass tempering furnace or loading dock to prevent accidental rolling during loading/unloading.
