How grab selection changes coil storage density, automation readiness, and facility capacity.
CareGo’s technical whitepaper compares the major overhead crane grab types used in metal coil handling and shows how each one affects row spacing, automation readiness, safety, throughput, and storage capacity.
What you’ll learn
- How C-hooks, fixed leg grabs, retractable foot grabs, crazy legs grabs, and electromagnetic magnets compare across the key performance dimensions.
- Why grab geometry directly affects minimum row spacing and storage density — and how much that difference compounds across a full storage bay.
- Which grab types best support manual, semi-automated, and fully autonomous crane operation.
- How a 72-foot storage bay scenario changes across grab types — from 891 coils with a C-hook to 1,434 with electromagnetic handling.
- Why planning grab selection alongside TELIA automation can help facilities increase storage capacity or recover valuable floor space for processing and packing lines.

The whitepaper compares grab types across row spacing, automation readiness, and 3-high storage capacity in a 72-foot bay scenario using 60-inch coils.
C-Hook
Manual baseline
Row spacing: 36–48 in
Operation: Manual / semi-auto
Fixed Leg Grab
Practical automation step
Row spacing: ~20 in
Operation: Semi-auto / auto
Retractable Foot Grab
High-density mechanical option
Row spacing: 12–15 in
Operation: Auto-ready
Electromagnetic Magnet
Maximum density option
Row spacing: 4–6 in
Operation: Auto-ready
From 891 to 1,434 coils in the same 72-foot bay.
That’s 543 additional coils in the 3-high scenario, depending on grab type and configuration.
