摘要： Apparatus for displacing a load, comprising a platform (1) with a telescopic boom (4) movable in the vertical plane, means mounted on the free end of the boom (4) for removably arranging attachments such as lift forks, a winch (10) supported by the platform (1) for a hoisting cable (9) guided along the boom (4) and having a hook for the load, wherein a jib (8) provided with a fixed top pulley (12) for the cable (9) is pivotally mounted on the free end of the boom (4), wherein the length of the jib (8) is such that, as seen in the vertical plane, for all positions of the boom (4) the vertical line along the top pulley (12) runs clear of these mounting means on the boom (4), whereby the apparatus can function better as hoisting apparatus. The apparatus can further be embodied with a synchronous control of the hoisting cable (9) and the telescopic boom (4).

摘要： A method for reducing resonant vibrations and dynamic loads of cranes, whose horizontal and vertical motion of the pay load are controlled by a boom winch controlling the luffing motion of a pivoting boom and a hoist winch controlling the vertical distance between a boom tip and the load. Where the method includes determining the resonance frequencies of the coupled crane boom and load system, either experimentally or theoretically at least from data on inertia of the boom and stiffness of at least a boom rope, a hoist rope, a pedestal and an A-frame. The method further includes automatically generating a damping motion in at least one of said winches, that counteracts dynamic oscillations in the crane, and adding this damping motion to the motion determined by a crane operator.
