USING THE WHEEL LIFT
The wheel lift of your wrecker should not be used as a way to increase anchor ability. This can cause damage to the wheel lift and the wrecker body itself. However, there are manufacturers that have created spade / outrigger attachments for wheel lifts. These should not be used unless the operator has a thorough understanding of the capabilities and limitations of the spade attachments.
TYING DOWN THE FRONT
The front of the wrecker should not be tied down to increase anchor ability under any circumstance. These tie downs put too much stress on the frame which can cause damage or lead to a catastrophic failure.
