Executive Summary
During a tear-out operation, an operator was struck by the boom, pinned against a wall, and taken to the hospital. On a LAG tear-out machine, that incident is an impossibility. The machine runs a pedestrian detection system built on AI cameras with specific detection zones: when a person is detected, the system slows the boom down, and it stops the boom completely before it ever comes within an arm’s length of contact.
What Happened When the Boom Pinned an Operator During Tear-Out?
The operator was out at the very end of the boom’s travel, swinging it back toward himself to go down into the trough for another scoop. For whatever reason, the boom kept traveling toward him and pinned him up against a wall. He was struck by the boom and ended up in the hospital.
How Does AI Pedestrian Detection Work on a LAG Tear-Out Machine?
The LAG tear-out machine uses AI cameras set up with specific detection zones around the machine. When a person is detected inside a zone, the system responds automatically: it either slows the boom down or stops it completely, depending on where the person is. The operator does not have to see the person or react in time, because the machine reacts first.
Why Is a Boom Strike an Impossibility on This Machine?
As the boom travels closer to a person, it slows down before it would ever make contact, well before it comes within an arm’s length. The boom cannot keep traveling into someone the way it did in that incident, because the detection system takes over before the distance closes.
Would That Operator Have Been Hurt on a LAG Machine?
In that same circumstance on this machine, that man would never have been hurt. He would not have gone to the hospital, and he would have gone home that day.
