Abstract: An arrangement for damping oscillation of a loading member in a crane includes a trolley, a hoisting mechanism, hoisting ropes, and a loading member. The arrangement includes a vertical guide projection arranged in an upper part of the loading member, and a guide part arranged in the trolley and receiving the guide projection. Damping members connected to the guide part are arranged in a separate support frame which is guidable into its place in a dock arranged underneath the trolley and which is lowerable off the dock onto the loading member. The guide part is a floating guide tube structure. The damping members include a plurality of side damping modules connected between a side wall of the guide tube structure and the support frame for substantially damping horizontal movement of the guide tube structure. A support joint is arranged in an upper part of the support frame.

Abstract: A system for determining a location of a vehicle in an environment provided with at least two landmarks whose location is known. The system includes at least one scanning distance sensor installed in the vehicle and configured to measure distance and direction from the vehicle to the at least two landmarks, as well as a data processing device configured to store in its memory the location of the at least two landmarks; and determine the location of the vehicle on the basis of at least the location of the at least two landmarks as well as the distance and direction from the vehicle to the at least two landmarks.

Abstract: A system is provided for identifying an operator and managing access rights in connection with a crane. The crane includes a control system and a controller positioned at a distance from it. The control system maintains a plurality of operator-specific parameters that define operator rights. An identifier reader is placed in connection with the controller for reading the operator's identifier by using a first connection. A second connection is set up between the identifier reader and the control system to send the operator's identifier, or information derived from it, to the control system. The control system compares the operations requested through the controller with the operator-specific parameters, which define operator rights, and allows the operation of the crane only within the scope of rights associated with the operator's identifier.

Abstract: A crane, particularly a rubber-wheel container crane including a frame which has, on opposite sides of its lower part, main beam structures at both ends of which, i.e. in the lower corners of the crane, there are in each particular case two successive rubber wheels or wheel arrangements through which the crane is supported to its moving carrier. These wheels are, in each particular case, supported to the main beam structure rigidly and in an unsuspended manner.

Abstract: A mobile crane including a frame which, in its upper part, is provided with a main support structure and which, in its lower part and on opposite sides of the lower part of the frame, is provided with lower beam structures transverse to the main support structure, and upright legs between the main support structure and the lower beam structures; at least one wheel or wheel arrangement at both ends of the lower beam structures, i.e. in each lower corner of the crane; a trolley arranged to move along the main support structure and provided with a hoisting member; at least one hoisting mechanism; at least one rope drum arranged to be run by the hoisting mechanism; and at least one rope arranged from the rope drum of the hoisting mechanism to the hoisting member for running it, the rope drum being further provided with at least one hoisting rope connected to at least one counterweight.

Abstract: A cask transport system includes a support assembly including a plurality of wheels and a support frame coupled to and supported by the wheels. The cask transport system also includes a tower disposed above the support assembly, the tower including a base portion and a tower frame coupled to the base portion, the tower frame movable relative to the base portion. The cask transport system also includes an upper beam assembly coupled to the tower frame, and a bottom block assembly coupled to the upper beam assembly, the bottom block assembly movable relative to the upper beam assembly.

Abstract: There is provided improved accuracy in cargo handling by a spreader (306) including a distance sensor (308a, 308b) transmitting optical signals. The handled cargo (312) includes a plurality of interconnected sides (312a, 312b). The transmission directions of the optical signals are selected and distances are measured by reflected optical signals transmitted in the selected directions. The measured distances are used to determine a reference line that matches a shape of at least one of the interconnected sides (312a, 312b) of the cargo (312).

Abstract: There is provided an apparatus, method, computer program product, and a kit and method for upgrading, an apparatus for moving cargo. A bus for transmission of electrical energy, at least one load connected to the bus, said at least one load configured to transform electrical energy from the bus into movement of a cargo with respect to the apparatus energy transforming means configured to transform energy between electrical energy of the bus and potential energy of a hydraulic accumulator, wherein the apparatus is configured to store electrical energy from the bus as potential energy to the hydraulic accumulator and to supply the potential energy stored in the hydraulic accumulator as electrical energy to the at least one load.

Abstract: Method/apparatus for performing the following acts on a system that includes an electrical motor followed by a gear, and a speed output unit: monitoring a first set of frequencies from the system over a measurement period when the system is in a known good operating condition; storing the first set of monitored frequencies or derivatives thereof as reference data in a long-term storage system; monitoring a second set of frequencies from the system over a measurement period when the system is in an unknown operating condition; comparing the second set of monitored frequencies with the first set of monitored frequencies in a frequency domain; in the frequency domain, detecting changes between corresponding frequencies resulting from the second set of monitored frequencies and the first set of monitored frequencies.
