Method for positioning load and fetching positioned load or stacking loads with crane

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.
