Slipped-up jack drops lift truck on mechanic, injuring him
seriously |
A mechanic put a lift
truck on supporting frames and tried to get under the chassis in an effort
to check the brushes of the electric motor. But he found the chassis
height was a bit too low for him to creep in, so he lifted it up further
and started the work. Then the jack slipped up all of sudden and fell
off on him. He was seriously injured. |
