An employee was raising and tilting the cab of a tractor utilizing a specialized tractor-specific tool. The hole on the tool did not line up with the tractor, so the bolt was not inserted in the tool. When the cab got to the tipping point, the arm of the tool slipped out of the cab frame, causing the cab to over-tilt and land on top of the employee, who was kneeling underneath it. The force of the cab caused the employee's legs to split, pinning him underneath the cab and resulting in a broken hip.
