Safety Jacks

The ARNOLD® safety jack reliably prevents your parked semi-trailer from tipping over during loading operations while at the same time being extremely easy to handle. The jack features sturdy wheels, so you can quickly place the safety jack underneath the trailer and then just adjust its height by means of either a spindle or a convenient 2-way winch.
