Abstract
A grappler spreader adapted for mounting on a fork lift or other type of cantilever-loaded carrier, and for handling cargo containers and piggyback trailers. The spreader to be described is especially designed for use on front or side-loading carriers. It is advantageously used in stacking and unstacking closely placed containers in terminal yards through provision of grappling arms which may be stored above the main frame of a spreader within a vertical projection of a cargo container handled by the spreader.
