发明名称 Safety stand for trailer loading
摘要 A collapsible trailer safety stand may be positioned adjacent the front of a loading bay a predetermined distance away from a dock. The stand in one position engages adjacent the kingpin of an unfettered trailer. It has a top and bottom and has located proximate its bottom a base having pivotally attached thereto at least one lifting arm and at least one stabilizing arm. 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. The collapsible safety stand in use prevents nose diving of the trailer when the trailer is being loaded or unloaded.
