PACKED ATTITUDE MAINTAINED LIFTING METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To make a cargo laid on a ground plane lifted while keeping its packed shape, even when the ground plane laid with the cargo is sloped.;SOLUTION: Plural hydraulic cylinders 14 are connected to a cargo 12. Both separation of the cargo 12 from a ground plane, and work that the hydraulic cylinder 14 in a portion floated from the ground plane by the separation hereinbefore in the cargo 12 is expanded to make the cargo 12 contact with the ground plane again are repeated thereafter. A lifting point approaches to a gravity center of the cargo 12 by the repetition of the work hereinbefore to restrain variation in the attitude of the cargo 12 before and after the separation from the ground plane.;COPYRIGHT: (C)2001,JPO
