20210039923 · 2021-02-11 · ·

The invention addresses the problem of providing a crane and a crane control method that can suppress load swaying when controlling an actuator on the basis of the load. The invention is provided with a turntable camera (7b) that detects the current position coordinates p(n) of a load W with respect to a reference position, wherein the invention: converts a target speed signal Vd to target position coordinates p(n+1) of the load W with respect to the reference position; calculates the current position coordinates q(n) of a boom (9) with respect to the reference position from a turning angle z(n), a hoisting angle x(n), and an extension/contraction length lb(n); calculates a feed amount 1 of the wire rope and the directional vector e(n) of the wire rope from the current position coordinates p(n) of the load W and the current position coordinates (n) of the boom (9); calculates the target position coordinates q(n+1) of the boom (9) with regards to the target position coordinates (n+1) of the load W from the feed amount 1 and the directional vector e(n) of the wire rope; and generates an actuator operation signal Md on the basis of the target position coordinates q(n+1) of the boom (9).

For the automated loading of a load by a crane system, a camera system of the crane system generates at least one image data stream. The at least one image data stream is analyzed by a computer unit with the assistance of an artificial neural network. On the basis of the analysis, a first marker and a second marker are recognized by the computer unit in respective single images of the at least one image data stream. Positions of the markers are determined, and the load is loaded automatically by a lifting device of the crane system dependent upon the positions of the markers.

Load control apparatus and method for controlling movement of a suspended load

A load control apparatus and method for controlling movement of a suspended load is disclosed. The load control apparatus includes: a base for attachment to or forming part of a load; a support element pivotally secured to and extending from the base for receiving and/or connecting to a lift line; and actuation means connected to the support element and to the base at respective positions which are spaced from the pivotal connection between the support element and the base such that actuation, in use, of the actuation means causes the base to pivot relative to the support element.

SIDAS—spreader impact damage avoidance system
10759635 · 2020-09-01 ·

Embodiments of this document provides improved safety logic for a mobile container handler of the reach stacker or top pick type. The improved logic involves limitations surrounding the hoist function of the machine subsequent to attaching to a shipping container. This improvement addresses damage to the container spreader caused by abrupt joystick hoist inputs by the operator immediately subsequent to attaching onto a shipping container. Due to space between the spreader arms and spreader body, which is so designed to facilitate movement of the arms inside the spreader body, sudden vertical movement of the spreader results in impact forces being exerted on various parts of the spreader body and spreader arms. These impacts accelerate fatigue leading to premature catastrophic failure of the spreader body and/or spreader arms' structural steel.
