The arms have pivotally attached therewith a support which moves from a first position wherein the support is disposed substantially within the base and the safety stand lays substantially flat in the loading bay to a second position wherein the support is disposed adjacent the kingpin. The arms are engaged with a drive to drive the support from the first position to the second position locating the mechanism adjacent to the kingpin of the tractor trailer.
