Handbook palletizing may look easy. However behind each elevate is a set of forces, postures, and dangers that add up quick, particularly when achieved a whole bunch of instances per shift.
That’s why the NIOSH Composite Lifting Index (CLI) exists. And should you’ve by no means heard of it earlier than, it’s time to get acquainted—as a result of it may very well be the important thing to defending your workforce and unlocking sooner ROI from automation.
Let’s break it down.
What’s the CLI?
The CLI is a device developed by the Nationwide Institute for Occupational Security and Well being (NIOSH). It measures the ergonomic danger of guide lifting duties within the office—particularly when a employee is lifting a number of objects, in several positions, at completely different frequencies.
In brief, it solutions this query:
Is that this elevate protected, or are you pushing your folks too far?
The upper the CLI, the better the danger of harm.
What the numbers imply
Right here’s the straightforward rule of thumb:
- CLI ≤ 1.0 → Acceptable for many employees
- CLI > 1.0 → Elevated danger
- CLI > 3.0 → Excessive-risk, pressing want for redesign or automation
Now think about this: One in every of your operators is palletizing 12 lb containers, 700+ instances per hour, with fixed bending and reaching. That’s precisely the kind of high-frequency, high-strain state of affairs the place CLI spikes—and harm danger skyrockets.
Why must you care?
As a result of a CLI of three.0 or greater doesn’t simply imply somebody may get harm. It means somebody seemingly will—and shortly.
Accidents brought on by overexertion and repetitive lifting are among the many commonest and dear office points:
- $39,000+ common value per again harm
- Misplaced workdays, misplaced output, rising insurance coverage prices
- Turnover and recruitment challenges
In case your CLI is excessive, your margins are already below strain.
.
Automation drops your CLI to zero
The best technique to scale back your CLI? Get rid of the guide elevate totally.
That’s the place cobot palletizing is available in. With a Robotiq system:
- You take away employees from the danger zone
- You get rid of ergonomic pressure on the supply
- You enhance consistency, security, and throughput
No lifting = no CLI = no harm danger.
And with Robotiq’s turnkey palletizing options, you may go from guide to automated in as little as 3 days—with out facility redesign or weeks of downtime.
Backside Line: Your Lifting Threat Has a Quantity
The Composite Lifting Index offers you a transparent, data-backed technique to consider danger. However you don’t have to grow to be an ergonomics professional to behave on it. In case your group remains to be palletizing by hand, the CLI is probably going already within the hazard zone.
So don’t look forward to the harm report.
