Durable and Easy-to-Install Stanchion Posts
The MDK-0060-C kit features two high-strength stanchion posts that securely anchor to concrete with four 3/4-inch-diameter anchors, providing a stable foundation for the lifeline. Each stanchion is engineered to withstand the extreme forces of a fall-arrest event, delivering a minimum ultimate tensile strength of 9,000 pounds per anchor. The straightforward mounting design allows crews to affix stanchions to the structure efficiently, minimizing downtime and maximizing job-site compliance.
Adjustable Horizontal Lifeline Cable for Versatile Job Site Safety
The 60-foot horizontal lifeline cable assembly is fully adjustable to fit varying spans. The 3/8-inch galvanized steel cable attaches securely to the stanchions using energy absorbers, combination clamps, and shackles. An integrated turnbuckle allows for precise tension adjustment, ensuring the correct sag for optimal system performance. Proper tensioning is critical, as it preloads the system and allows the shock absorber to function effectively during a fall. Regular inspection of the cable tension and sag is mandatory for safe operation.
Comprehensive OSHA Compliance and Performance Monitoring
The Malta Dynamics MDK-0060-C complies with all relevant OSHA standards for horizontal lifelines. The system is designed to arrest falls by utilizing a combination of cable stretch, post-deflection, and expansion of the P-00039-1 Inline Shock Absorber. The absorber features a visual deployment indicator, allowing safety managers to quickly identify if the system has been stressed and requires removal from service.

Malta Dynamics MDK-0060-C Lifeline Kit FAQ
1. Can this system be used by more than two workers?
No. The MDK-0060-C is specifically tested and rated for a maximum of two users. Exceeding this limit increases the total force on the stanchions and the cable sag during a fall, which can lead to system failure or ground impact.
2. What is the maximum span between stanchion posts?
The maximum span for this temporary system is 60 feet. If your work area exceeds 60 feet, you must install intermediate stanchions or use multiple kits. Spanning more than 60 feet without intermediate support will result in excessive cable sag, requiring more fall clearance than is typically available.
3. How do I know if the cable is tensioned correctly?
The system must be tensioned using the turnbuckle until the required sag is achieved. Refer to the MDK-0060-C Instruction Manual above for the specific tensioning chart. A system that is too loose will result in a longer fall, while a system that is too tight can put excessive stress on the stanchion anchors.
4. Does this kit work on both I-beams and concrete?
Yes, the stanchions in the "C" (Concrete) kit are designed to be bolted to concrete substrates using 3/4-inch mechanical or adhesive anchors. However, they can often be adapted for steel beams with appropriate base-plate modifications or different mounting hardware. Always verify your specific substrate with a Qualified Person before installation.
5. What is the required fall clearance for this system?
Fall clearance for horizontal lifelines is complex. It must account for the worker's height, the lanyard length, the cable's sag (deflection) during a fall, and a safety factor. The total clearance required often exceeds 20 feet. Always perform a clearance calculation before use.
6. What should I do if the shock absorber indicator is visible?
If the P-00039-1 Shock Absorber shows any sign of deployment (visible warning tape or expansion), the entire lifeline system must be removed from service immediately. This indicates the system has arrested a fall or been subjected to extreme force and is no longer safe to use.
7. How do I avoid common mistakes during HLL installation?
- 1. Improper Anchor Strength: Ensure the concrete has sufficient PSI (typically 3,000+) to support the anchor bolts.
- 2. Cable Termination: Ensure all wire rope clips (clamps) are installed in the correct direction ("Never saddle a dead horse") and torqued to spec.
- 3. Missing Shock Absorber: Never install an HLL without the inline shock absorber; the forces on the stanchions during a fall would likely cause structural failure.
