Abstract (en)
[origin: EP0467783A1] The method makes it possible to control the movement of a swinging load suspended from a support which is horizontally mobile and moved from a departure point to an arrival point during a journey of predetermined duration (T). The movable support (40) is subject to a support movement law x(t) determined such that the movement of the swinging load (20) is regulated by a load movement law X(t) satisfying the following conditions: X''(t) is continuous and derivable according to the time variable t, X''(t) = 0 and X'''(t) = 0 for t>/=T. Use especially for port lifting engines such as cranes, gantries for buckets or for containers. <IMAGE>
