Abstract: A lifting attachment for lifting one or more containers, comprising a lifting attachment frame and an arm on each end of the lifting attachment frame, wherein the arm comprises an upper locking mechanism and a lower locking mechanism. Each arm further comprises a pivotable extension connected to an actuator, wherein a proximal end of the extension comprises a pivot point connecting the extension to the arm and a distal end of the extension comprises a support portion, wherein in a resting position the distal ends of the extensions are turned to move the support portions to each other and in an operating position the distal ends of the extensions are turned downwards for supporting the container from its side.

Abstract: A method positions a load and fetches a positioned load or stacks loads with a crane having location measurement arranged thereto. The method includes taking a load to a selected position; detecting the unloading of the load mainly automatically; storing coordinate information of the load position mainly automatically into the memory of the crane or its control; when fetching a load or adding loads to a stack, activating, at a selected first time instant, a positioning switch arranged in the crane and connected to the memory, whereby coordinates of a load or stack most advantageously positioned relative to the movement of the crane are selected, after which the crane begins to move to said coordinates; and then hoisting or lowering the load at the selected coordinates, and at a selected second time instant, deleting the coordinate information associated with the position of the load from the memory.

Abstract: An apparatus for collecting energy in connection with a sheave system in a hoisting apparatus provided with a sheave system. The apparatus includes at least one generator including a rotor and at least one stator. The rotor is connected rigidly to a sheave of the sheave system, and the at least one stator is connected rigidly to the sheave system such that when the load of the hoisting apparatus is rising or lowering, said at least one sheave rotates, whereby the rotor rotates simultaneously but the stator does not rotate, whereby electric energy is induced in the stator. The apparatus further includes electric energy storage, a device for modifying induced electric energy and storing it in energy storage; and a device for supplying energy from the energy storage to at least one consumption device. The consumption device may be, for example, a working lamp, sensor, measuring device, communications device, signal device, charging plug or a combination of these mounted in connection with the sheave system.
