Problems solved by technology

However, they do not actively operate to minimize or in any case reduce load sway during operation of the bridge crane
[0018] Likewise, while there exist theoretical studies addressing problems involving load sway in lifting gear, the studies are generally based on simulations or laboratory prototypes, and generally do not take into account conditions in the industrial field such as those caused by operators and reference standards and other factors. The need to send the instruction exists due to the

Embodiment Construction

[0057] The present invention relates to apparatus and processes for controlling the swing of loads suspended by cable or chain hoists, such as overhead cranes, construction tower cranes, electric cranes, and similar devices that lift and move loads. For the sake of clarity, reference will be made to the description of an overhead crane.

[0058] figure 1 An overhead crane 10 is schematically shown presenting a bridge 19 comprising two mutually parallel beams 15, 16 which can be extended along the figure 1 The movement in the first direction, denoted by an X, is achieved by the movement of the two heads 13 , 14 along the two beams 33 , 34 .

[0059] Mounted on the bridge 19 is a motorized carriage 20 which can slide on two guide rails 15 ′, 16 ′, each on a corresponding beam 15 , 16 of the bridge 19 . The carriage 20 can slide in a vertical direction denoted by Y perpendicular to the first direction X. As shown in FIG.

[0060] The bridge 19 is associated with a motor 24 equ...

Abstract

An embodiment of the present invention discloses a device for controlling a swinging of a load suspended from a motorized slidable element which can move along a substantially horizontal axis, the controlling device comprising a control unit and an inertial platform, the inertial platform being able to detect representative values of an inclination angle of a cable that supports the load with respect to the vertical and being provided with means for communicating the values to the control unit, wherein the control unit is provided with means to measure and control the speed of the motorized slidable element and is able to process the values representative of the inclination angle of the cable with respect to the vertical so as to calculate and to impart control actions in order to dynamically the speed of the motorized slidable element as a function of a desired inclination angle of the cable with respect to the vertical.

Description

technical field [0001] The present invention relates to an apparatus and method for controlling the oscillation of a load suspended by a cable or chain hoist such as overhead cranes, construction cranes, electric hoists and similar devices for lifting and moving loads . Background technique [0002] As known, an overhead crane is a machine designated to lift and move materials and goods not only in outdoor environments but also in indoor environments, and generally consists of a machine that can move in the horizontal direction along a pair of guide rails and has a carriage mounted thereon. Constructed of a bridge of cross-members, the carriage houses a hoist that can move horizontally along the cross-members. A winch is connected to the hoist, and the winch has a grip, such as a hook, for gripping and raising an object. [0003] A winch has one or more cables applied to it through which the system of hoists, relays and hooks enables the lifting and movement of heavy objec...
