The harrowing incident unfolded at the Vandapac factory located in Thailand's Chonburi province on March 27.
The unsuspecting worker appeared to be laying out sheets of material when the arm forcefully swung down and pinned him against a bench.
Unsettling CCTV footage shows how the victim was incapacitated beneath the hulking metal device as a fellow employee continued working across the room, seemingly unaware of the catastrophe unfolding just behind him.
Emergency responders swiftly intervened after the alarm was eventually raised, releasing the man before administering critical aid and rushing him to Chonburi Hospital.
But he was pronounced dead on arrival having sustained major trauma.
