Knockdown SAFE A-Frame System
Complete knockdown A-frame system with factory-welded RockLock™ mounting
Build Structure Before Instability Begins.
The Weld-On Knockdown SAFE A-Frame with RockLock™ is a modular heavy-duty slab handling system supplied by Safe Stone Handling for utility-trailer or stationary warehouse use.
Developed by an engineer with 30+ years of industry experience solving slab handling challenges.
SSH supplies the A-frames with the sliding mounting plates factory-welded in place. The adjustable horizontal tubes and RockLock™ assembly complete the system. It uses the same slab-by-slab RockLock stabilization principle as the SAFE Truck A-Frame while allowing compact shipment and quick on-site assembly.

How the Universal Knockdown SAFE A-Frame System Controls Slab Stability
1. Position the two SSH A-frames and connect them using the adjustable horizontal tubes through the factory-welded sliding plates.
2. Adjust the spacing between the A-frames to suit the slab length and application.
3. Position the RockLock™ assembly along the supporting tubes as required.
4. During loading use RAISE → LOAD → LOWER → SECURE with each incoming slab.
5. During unloading use RAISE → REMOVE → LOWER → SECURE, lowering RockLock immediately against the next remaining slab.
