|---|---|---|---|
| Standard A-frame | 8-15 slabs | Raw slab storage | $800-$3,000 |
| Heavy-duty A-frame | 15-30 slabs | High-volume storage | $2,000-$5,000 |
| Bundle rack | 10-20 slabs (bundled) | Receiving from distributors | $1,500-$4,000 |
| Mobile A-frame | 4-8 slabs | Moving slabs within the shop | $1,000-$3,000 |
| Remnant rack | 20-40 pieces | Small piece and remnant storage | $500-$2,000 |
Why every shop needs them:
- Slabs stored flat on the ground risk cracking under their own weight
- Upright storage makes individual slab selection easy without moving other slabs
- Proper racks prevent leaning slabs from falling -- a major safety hazard
- Rubber or wood contact surfaces prevent edge chipping
- Organized storage speeds up slab selection and reduces search time
Considerations:
- Floor must be level and strong enough to support loaded rack weight
- Rack capacity must match slab sizes -- 3cm exotic slabs are heavier per slab than 2cm commodity granite
- Indoor storage racks should be near the bridge saw to minimize transport distance
- Outdoor storage racks need weather protection for sensitive materials

| Best For | Moving slabs between machines within the shop |
6. Overhead Bridge Cranes -- Best for High-Volume Shops
Overhead bridge cranes span the width of the shop and travel its length on rails mounted to the building structure. Combined with vacuum lifters, they provide the fastest and safest way to move full slabs anywhere in the shop.
Types for stone shops:
- Single girder bridge crane -- lower headroom, suitable for most shops ($15,000-$35,000 installed)
- Double girder bridge crane -- higher capacity and span ($25,000-$60,000 installed)
- Jib crane -- serves a single work station, lower cost ($5,000-$15,000 installed)
Why high-volume shops invest in them:
- Move full slabs from storage to any machine in the shop without a forklift
- No floor-level obstructions (forklifts, trolley tracks) to impede foot traffic
- Combined with vacuum lifters, one operator can move a 1,200 lb slab safely
- Continuous overhead access to every work station
- Reduces slab handling time by 50-70% compared to forklift-based movement
Considerations:
- Requires structural building support (not all shop buildings can handle the load)
- Professional installation required ($5,000-$15,000 in installation costs)
- Higher initial investment than trolley-based systems
- Maintenance of hoist, rails, and electrical systems needed

The Cost of Poor Slab Handling
Inadequate handling equipment causes three types of costly problems:
Slab Breakage
A dropped or shifted slab during handling can crack or shatter. At $500-$3,000 per slab (and $5,000-$15,000+ for exotic materials), even one breakage incident per month adds $6,000-$36,000 in annual material losses.
Worker Injuries
Stone fabrication has one of the highest injury rates in manufacturing. Back injuries from manual lifting, crushed fingers and toes from dropped slabs, and struck-by incidents from falling stored slabs are the most common. A single workers' comp claim for a back injury can cost $20,000-$80,000.
Production Delays
Inefficient slab movement creates bottlenecks. If your bridge saw operator waits 15 minutes between jobs for the forklift to deliver the next slab, that is 1-2 hours of idle saw time per day. At $200-$500 per hour of saw operating cost, that is $50,000-$125,000 in annual lost productivity.
Setting Up an Efficient Slab Flow
The optimal slab flow through a fabrication shop minimizes handling:
- Receiving -- Slabs unloaded from delivery truck to outdoor A-frame racks (forklift or crane)
- Selection -- Slabs moved from outdoor storage to indoor staging area (forklift or crane)
- Bridge saw -- Slab lifted from staging to saw table (crane + vacuum lifter)
- CNC router -- Cut pieces moved to router on trolleys or by crane
- Polishing -- Pieces moved to edge polisher on trolleys
- Quality check -- Finished pieces inspected and staged for delivery
- Loading -- Finished pieces loaded onto delivery truck with A-frame carts
Each handling step is an opportunity for damage. Fewer steps between receiving and shipping mean less risk and faster throughput.
Tracking which slabs are where in this flow -- from yard to machine to truck -- is where inventory software makes a real difference. SlabWise's Slab Inventory tracking shows exactly where every slab is in your production flow, reducing search time and preventing the "where did that slab go?" delays that plague busy shops.
FAQ
What is the safest way to lift a stone slab?
A vacuum lifter attached to an overhead crane is the safest method. The vacuum distributes load evenly, the crane provides controlled vertical and horizontal movement, and one operator can manage the entire lift without physical strain.
How much does a granite slab weigh?
A standard 3cm granite slab (typically 115" x 72") weighs approximately 750-950 lbs depending on the stone's density. Larger jumbo slabs can exceed 1,200 lbs. Marble and quartzite weigh roughly the same; porcelain slabs are significantly lighter.
Can I use a forklift instead of a crane?
Yes, forklifts are commonly used for moving slabs on A-frame carts. However, they create floor-level traffic, require wider aisles, and present more risk of collision in busy shops. Overhead cranes are safer for high-traffic environments.
How should I store stone slabs?
Store slabs upright on A-frame racks at 70-80 degrees from horizontal. Never stack slabs flat -- they can crack under their own weight. Keep racks on level, reinforced floors. Protect sensitive materials (marble, light-colored granite) from weather and direct sunlight.
What handling equipment do installation crews need?
At minimum: carry clamps (Stone Pro Crabs or equivalent), a portable vacuum lifter (Omni Cubed or similar), moving blankets, and edge protectors. A two-person crew with proper equipment can install most residential kitchen countertops.
How do I prevent slab breakage during transport?
Use rubber-lined A-frame racks in the delivery truck, secure slabs with ratchet straps, and drive carefully over bumps. Never stack slabs flat in a truck. Use corner protectors on finished pieces.
How much floor space do slab racks need?
A standard A-frame rack holding 10 slabs requires approximately 60-80 sq ft of floor space (including access clearance). A shop storing 50 slabs needs 300-400 sq ft dedicated to slab storage.
Should I buy new or used handling equipment?
A-frame racks and carry clamps are safe to buy used -- they are simple steel/rubber products. Vacuum lifters should be bought new or from a certified refurbisher, since a vacuum failure during a lift is a serious safety hazard. Cranes should be professionally inspected before purchase if used.
