Pro-Dolly™ HD3

Pro-Dolly™ HD3 — All-Terrain Stone Slab Dolly Rated to 1,200 lbs

The Pro-Dolly™ HD3 is a heavy-duty stone slab dolly engineered for fabricators and installation contractors who need to move large-format stone, quartz, porcelain, and similar slab materials safely across job-site terrain. Built on an anodized aluminum framework, it delivers a 1,200 lb load capacity while keeping its own weight to just 29 lbs, making it practical for a single operator to carry and deploy. The integrated clamping system with a machined billet aluminum tightening handle secures slabs up to 76.2 mm (3 inches) thick, and 9-inch closed-cell polyurethane flat-free tires handle rough or uneven surfaces without marking finished floors. It ships as a complete, ready-to-use unit and includes one dolly with holding clamp.

Technical Specifications

Model Comparison

The HD3 is the lighter, lower-profile option in the Pro-Dolly lineup, weighing 29 lbs versus the HD4's 37 lbs, and features a carry handle for easy single-operator transport between work areas. Contractors handling standard slab thicknesses up to 3 inches will find the HD3 covers the majority of natural stone, engineered quartz, and large-format porcelain applications without the added bulk of the wider-clamping HD4 model.

Key Features & Benefits

1,200 lb Load Capacity

The HD3 is rated to carry up to 1,200 lbs per dolly, making it suitable for full-size stone and quartz slabs that would otherwise require multiple handlers or mechanical lifting equipment. This capacity allows contractors to move heavy material efficiently with a compact, manually operated tool.

Anodized Aluminum Framework

The anodized aluminum frame keeps the dolly's own weight to just 29 lbs while providing a corrosion-resistant structure that holds up in wet shop and job-site environments. The low self-weight makes it practical for a single operator to carry the dolly to and from the work area.

Machined Billet Aluminum Tightening Handle with Integrated Clamp

The integrated clamping system uses a machined billet aluminum tightening handle and zinc-plated steel clamp shafts to grip slabs up to 76.2 mm (3 inches) thick securely. PVC clamping pads and EPDM padding strips on the support rails protect finished slab surfaces from scratching or marring during transport.

9" Flat-Free, Non-Marking Polyurethane Tires

Closed-cell polyurethane tires eliminate the risk of flats on debris-strewn job sites, ensuring the dolly remains operational throughout the workday. The non-marking compound protects finished flooring surfaces during interior installation work.

Low-Profile Deck with Carry Handle

At 3-1/2" to the bottom of the deck and 6-1/8" to the top, the HD3's low-profile design makes it easier to slide under slabs resting on A-frames or storage racks. The integrated carry handle allows quick repositioning between lifts without additional handling equipment.

Durable Mixed-Material Hardware

Stainless steel and zinc-plated steel hardware throughout the assembly resists corrosion from water, stone slurry, and outdoor exposure. This material selection extends service life in the demanding conditions typical of stone fabrication shops and construction sites.

Common Applications

Stone Slab Transport on Job Sites

Move full-size natural stone or engineered quartz slabs from delivery vehicles to installation areas across uneven terrain, including gravel, thresholds, and rough concrete.

Fabrication Shop Material Handling

Reposition slabs between cutting, polishing, and staging stations within a fabrication facility without requiring a forklift or overhead crane for every move.

Interior Installation Work

Transport slabs across finished flooring during countertop or cladding installation; non-marking tires protect completed surfaces from damage.

Loading and Unloading Deliveries

Offload stone slabs from flatbed or A-frame delivery trucks and move them to a staging area, reducing manual lifting strain on the crew.
