Having done some forklift driving this picture caught my eye. The biggest I drove was about 7t so it wasn't in that league. And I've had the back wheels lift but not as spectacularly as that. That will cost thousands to get the forklift back on its wheels.
I imaging that the driver would have been asked that, next time he is passing the manager's office he might like to drop in and explain himself!
