RockLock™: The Adjustable Arm Safety System That’s Changing the Industry

Shipping Containers Pose Hidden Dangers. These Two Solutions Protect Workers—and Your Bottom Line.

Every day, thousands of pounds of stone and porcelain slabs arrive at ports and job sites packed inside shipping containers. But the risk doesn’t stop at customs.

When slabs aren’t properly restrained during transport—or are mishandled during unloading—the consequences can be catastrophic. From crushed limbs to shattered inventory, a single incident can cost tens of thousands… or worse.

That’s why Safe Stone Handling created two advanced solutions to eliminate container-related risks:

What Kind of Materials Are You Handling?

✅ Choose this if you’re importing stone slabs vertically packed without A-frames and need to keep them locked in place during transport.

✅ Choose this if you're dealing with ultra-thin, flat-packed slabs that are vulnerable during unloading or tilting.

The Risk is Real: Slab Accidents Happen Fast in Containers

Every year, stone slabs shift and fall during unloading—causing devastating injuries, damaged inventory, and regulatory violations. Containers often arrive with loose or flat-packed slabs that are unstable and difficult to control.

❌ Multiple OSHA cases involving slab fatalities during unloading

❌ Fragile porcelain slabs frequently crack due to improper vertical lifting

❌ Heavier stone bundles can tip when bracing is removed.

Two Container Safety Systems. One Mission: Prevent Tragedy.

At Safe Stone Handling, we’ve engineered two specialized safety products to meet the very different needs of container shipping—from delicate flat-packed porcelain to high-weight vertical stone bundles.

Each system reduces liability, protects your workers, and streamlines slab transfer into your warehouse or onto A-frames.

⚙️ Explore the Right Safety Solution for Your Shipping Needs

Shipping containers are one of the most unpredictable and hazardous environments in the stone supply chain. Choosing the right safety system depends on the type of material you're handling—and how it’s packed inside the container. Below, choose the solution that fits your specific risk:

Large Format Porcelain Slab Handling Frame

(for flat-packed porcelain/Dekton slabs)

Delicate porcelain and Dekton panels are often shipped horizontally—creating extreme breakage risks during unloading.
This lightweight yet heavy-duty frame uses adjustable suction cups and a secure tilt mechanism to lift fragile slabs from flat to vertical safely. It’s the modern alternative to clamp-and-hope methods that often result in cracked inventory.

  • Designed for fragile 6–12mm slabs

  • Uses multi-point suction for even weight distribution

  • Reduces risk of chipping, cracking, or collapse

  • Tilts from horizontal to vertical with complete control
