More Information About 3D Model :
A heavy-duty swivel caster featuring a dual-wheel configuration with red polyurethane (PU) tread is an specialized material handling component engineered for industrial environments requiring maximum load distribution, superior floor protection, and enhanced maneuverability under extreme stresses. This apparatus, also referred to as a roller or rig, is classified by its robust construction designed to withstand continuous operation with dynamic loads exceeding standard industrial specifications.

### I. Structural Design and Load Capacity

The designation "Heavy Duty" implies the use of substantial materials, typically high-tensile steel plate (e.g., A36 or equivalent high-carbon alloys), ensuring exceptional structural integrity. The primary load-bearing components include the top plate (affixing the caster to the equipment), the yoke (the fork assembly supporting the axle), and the swivel raceway. The yoke assembly features thickened legs and reinforced welding or riveting to prevent deformation or failure under lateral or shock loading.

The swivel mechanism is critical for maneuverability, allowing the wheel assembly to rotate 360 degrees relative to the mounting plate. Heavy-duty swivel casters typically employ a precision double ball-bearing raceway, hardened through heat treatment, to absorb significant axial thrust and radial side loads while minimizing rolling resistance. The swivel section often includes a lubrication grease fitting (zerk) to facilitate maintenance and ensure smooth operation over long periods. Optional features often include a total lock or tread brake mechanism, which engages both the swivel motion and the wheel rotation simultaneously.

### II. Dual Wheel Configuration

The dual wheel arrangement distinguishes this caster type, offering several distinct advantages over traditional single-wheel casters. By distributing the total load across two independent rolling surfaces mounted in close proximity on a common or dual axle configuration, the following performance benefits are realized:

1. **Reduced Floor Pressure:** The wider footprint decreases the pressure exerted per square inch (PSI) on the floor surface, making it safer for delicate or coated flooring materials.
2. **Enhanced Load Stability:** Dual wheels mitigate instability associated with uneven surfaces, especially when traversing gaps or floor joints.
3. **Increased Working Load Limit (WLL):** The shared load capacity allows the caster rig to support significantly heavier static and dynamic loads.
4. **Improved Turning Radius:** The differential friction generated between the two tires during tight turns assists in pivoting, reducing the force required for directional changes.

### III. Wheel Material: Red Polyurethane

The rolling element (wheel tire roller) utilizes a polyurethane (PU) tread, known for its superior material properties compared to rubber or phenolic resin. Polyurethane is a thermoset polymer elastomer characterized by:

* **High Load Capacity and Resilience:** PU offers a higher WLL than rubber while retaining elastic properties necessary for cushioning impact and shock absorption.
* **Abrasion and Chemical Resistance:** It exhibits excellent durability against tearing, cuts, chipping, and exposure to oils, grease, solvents, and mild acids.
* **Non-Marking Properties:** Polyurethane tires are universally non-marking, preventing black streaks on concrete, epoxy, or tiled floors.
* **Color Coding:** The red pigmentation is often standardized across manufacturers to denote a specific durometer hardness (e.g., Shore D 90-95) or a specific load rating classification within an organization’s inventory system. The PU tread is typically chemically or mechanically bonded to a robust wheel core, often cast iron, forged steel, or high-density polyolefin, selected to withstand high stress and thermal buildup.

### IV. Industrial Applications

Due to their robust design and specialized material composition, these heavy-duty swivel casters are principally employed in demanding industrial settings where equipment frequently moves extremely heavy loads. Typical applications include: aerospace manufacturing, automotive assembly lines, heavy equipment fabrication facilities, shipyard operations, large machinery dollies, and specialized transport carts utilized in harsh chemical or temperature environments.
