Abstract: A method and equipment for controlling a lifting device, wherein a main steering direction of the control device used by an operator is selected from at least two options; the impact of the control device on the directions of motion of the lifting device is changed according to the selected main steering direction; and the lifting device is controlled with a control device.

Abstract: A crane anti-collision system, containing: a scanning apparatus installed in the crane, containing a laser scanner arranged to measure the optical distance to targets from the crane in the first direction of travel; and a detection apparatus arranged to automatically detect targets by the scanning apparatus. The detection apparatus is arranged for: defining by the scanning apparatus a three-dimensional reference zone of the goods handling area that is composed of the surface and vertical tolerance of the goods handling area; and detecting a target in the goods handling area on the basis that the height defined by the scanning apparatus differs from that of said reference zone. Further described is a control system, an anti-collision method, an anti-collision program, and a manufacturing method for an anti-collision system.

Abstract: A method and optical detection equipment for monitoring a container transfer device on lowering a container onto or lifting away from a transport platform. The container, its pin holes' position and the position of the lock pins of the transport platform are determined by the optical detection equipment, which includes a group of optical detection devices measuring obliquely from up the container and the transport platform during lowering or lifting of the container such that positions of the container and the lock pins are determined based on the measurement of the same optical detection devices.

Abstract: A rope drum for drawing and releasing a rope under tensile stress. Support segments are arranged to provide a number of grip sections for supporting the rope through the grip sections as a continuous spiral surrounding the rotated drum part by at least two rounds so that, when the drum part is rotated, a number of grip sections move due to the guidance of the support segments along the drum part depending on the rotation direction of the drum part towards the first end of the drum part or towards the second end. Prevention grooves or ridges together with the support segments restrict the movement of the grip sections supporting the rope on the drum part with regard to the drum part in the direction of the perimeter to a maximum that is defined by the mutual geometry of the prevention grooves or ridges and the support means.

Abstract: A method and equipment for detecting with smart glasses used by the operator an target intended by the operator; detecting a driving command given by the operator; and responsively to the detection of the driving command steering the loading member or the load towards said target.
