Abstract
In a device for regulating the transfer of a load suspended by cables from the carriage of a lifting machine the carriage speed is controlled by means of a position corrector and an angle corrector weighted outputs of which are summed to establish the speed set point. The lifting machine operator has an operating mode selector connected to a control unit which enables the correctors as appropriate to the selected control mode.
