An employee was helping a coworker rearrange a crate (weighing 706 pounds) with an electric pallet jack. He was standing at the end of the forks and leaned the wooden crate to get it off the forks. His coworker then lowered the forks, which bumped the ground, and the crate tipped. He tried to stop the crate from falling, but it fell on his right leg, fracturing it between the knee and foot, and requiring hospitalization.
