Abstract
A tool permitting a longshoreman to install and remove stacking pins from cargo containers without the necessity of using a ladder is disclosed. The stacking pin tool includes a segmented, elongated, handle with one end segment thereof terminating in a specifically designed stacking pin engagement and retention structure for a specific design stacking pin. The longshoreman remains on the deck while engaging and retaining the stacking pin with the end of the tool, rotating the tool and pin 180.degree. to individually position stacking pins over and in position to be inserted in each of the four reinforced corners of a cargo container. The length of the elongated handle is adjusted by adding or removing segments therein for use in one or two tier cargo container stacks. When needed, a second elongated tool, having a flashlight and mirror on one end thereof, is employed by a second longshoreman to illuminate the reinforced corner area and assist the first longshoreman, via the mirror image, to position the stacking pin within the corner opening.
