This is the shocking moment a tower of massive shipping containers crashes down on top of a dockside forklift truck driver after he moved the wrong one.

CCTV footage shows the worker attempting to shift the last container in a row but accidentally clipping one of the containers in the adjacent stack at the Pasir Panjang Terminal in Singapore on November 25.

In horrific slow motion, all six containers start to topple, crashing down onto his truck in a dramatic scene reminiscent of a giant game of Jenga.

The highest one falls around 60ft before it smashes down the roof of his forklift cab, sending him sprawling out of the back as the footage ends.

Local media reported that the 37-year-old dock worker remained conscious when paramedics arrived, and he was rushed to the National University Hospital.

His condition was later reported as stable.
