Dolly & Hand Truck Caster Overview
Dollies and hand trucks are workhorses, they move constantly, carry heavy loads, and take more abuse than most other equipment in a facility. Their casters need to handle it all: concrete, pavement, dock plates, elevator thresholds, and everything in between.
Whether you're replacing worn wheels on a moving dolly or upgrading a fleet of furniture dollies, understanding the right caster specification for your equipment type and operating environment is essential. From platform dollies in warehouses to convertible hand trucks on loading docks, the right wheel material, diameter, and mounting style make the difference between equipment that works and equipment that fails.
Types of Dollies & Their Caster Requirements
-
Platform Dollies
The most common material handling dolly in warehouses and loading docks. Uses 3"-5" polyurethane or rubber swivel casters with plate mount. Standard bolt patterns are 2-3/8" x 3-5/8" or 2-1/4" x 3-1/4". Load capacity ranges from 500-1,500 lbs per dolly.
-
Moving Dollies
Used by movers and rental operations for household and office furniture. Requires rubber or soft polyurethane wheels for floor protection. Carpet-friendly wheels are important for residential moves. Typically 3"-4" diameter in 4-swivel or 2-swivel + 2-rigid configuration.
-
Convertible Hand Trucks
Hand trucks that convert between upright 2-wheel and horizontal dolly mode. Rear wheels are typically pneumatic or solid rubber for outdoor and dock use. Standard tire diameter is 8"-10" with pneumatic or solid flat-free replacement options.
-
Warehouse Dollies
Heavy-duty dollies for moving full pallets or skids. Uses 5"-8" phenolic or polyurethane wheels with load capacities of 2,000-5,000 lbs total. Kingpinless swivel rigs recommended on heavier configurations for maximum durability.
Choosing the Right Wheel for Your Dolly Surface
| Surface | Recommended Wheel | Notes |
|---|---|---|
| Finished Wood Floors | Soft rubber or soft polyurethane | Floor protection priority |
| Epoxy / Painted Concrete | Non-marking polyurethane | Prevents surface damage |
| Rough Concrete / Warehouse | Polyurethane or solid rubber | Durability on rough surfaces |
| Dock Transitions | Large diameter PU or pneumatic | Handles elevation changes |
| Outdoor Pavement | Pneumatic or large solid rubber | Shock absorption outdoors |
| Mixed Indoor/Outdoor | 4"-6" polyurethane or flat-free | Versatile all-surface use |

Frequently Asked Questions
A hand truck is a two-wheel L-shaped device used upright to tilt and roll loads. A dolly is a flat platform on 4 casters used horizontally to roll loads on their base. Many hand trucks convert between both configurations.
Probably. Dolly wobble typically comes from worn swivel rig bearings that have developed play, a bent or damaged swivel rig from impact, or uneven wheel wear. Inspect each caster: spin the wheel and swivel the head, grinding, wobble, or stiffness indicates replacement is needed.
Yes, moving dollies use standard plate mount swivel casters. The key requirement is non-marking wheel material (rubber or polyurethane) to protect customer floors.
