AMH – All Material Handling

Replacing an escalator is never a straightforward task. With heavy components, tight structural envelopes, and limited overhead clearance, every move demands deliberate coordination and rock-solid rigging. A recent project (captured in the accompanying image) highlights how modern riggers are using advanced hardware and concise planning to safely execute one of the most challenging lifts in the vertical transportation world.

Central to the setup are CARTEC in-line chain sling shorteners, deployed to maintain precise load control while navigating the confined geometry of the tunnel. These devices allow riggers to fine-tune sling lengths and leg angles on the fly, ensuring the suspended escalator sections remain level during extraction and repositioning. In operations like this, where inches matter and shifts in load distribution can create serious hazards, the ability to make micro-adjustments is critical.

Equipped with CARTEC integrated shortening hooks, the chain slings eliminate the need for additional hardware or improvised solutions. The hooks positively engage the chain links without degrading working load limits, enabling fast, secure shortening while keeping the rigging envelope compact—a major advantage in low-headroom environments. This integrated approach reduces clutter, minimizes snag hazards, and helps crews maintain a clean, predictable load path throughout each phase of the lift.

The image shows these components working in unison: chain slings balanced across multiple lift points, tension equalized through strategic shortening, and hoists rigged to accommodate both vertical and angular load demands. It’s a real-world example of how integrated shortening of chain slings is driving efficiency and safety in complex escalator replacement projects.
