The present invention provides, for load compensation, different kinds of elastomeric load compensators placed at various locations on the crane for increased flexibility and for shock and vibration absorption. The elastomeric load compensators employ elastomeric tension elements, elastomeric torsion elements, or elastomeric shear elements. Elastomeric tension elements can be simply inserted in series with the main hoist rope. An elastomeric load compensator employing elastomeric torsion elements is mounted to the underside of the boom for receiving the live end of the main hoist rope. A single stack of elastomeric shear elements is suitable for mounting a hoist or winch or an idler sheave to the crane structure. For additional load compensation, the hoist, winch, and idler sheaves are mounted on rails for increased displacements under heave loads, and the increased displacements are compensated by elongated elastomeric tension elements or multiple elastomeric tension, torsion or shear elements in series.

The present invention relates to a radio control-operated autonomous load leveler for cranes with: - a support (1) with a crane hitch (2); - an electric power generator; - a remote control system for wirelessly receiving commands; - load leveling means for handling the load depending on commands received by the remote control system, comprising: • at least one hydraulic winch or block and tackle (3,4); • a electrohydraulic pump (6); • a hydraulic liquid tank (7); • a hydraulic distributor (8); • one electrovalve (9) for each hydraulic winch or block and tackle (3,4) powered by the electric power generator for activating the corresponding hydraulic motor (4) depending on the commands received by the remote control system.
The invention can be applied to a load lifting operation with cranes, for shortening or lengthening the chains or slings remotely and the load being suspended, preventing the continuous handling of the load by operators.
摘要:
Die vorliegende Erfindung betrifft eine Kransteuerung für einen Kran, welcher ein Hubwerk zum Heben einer an einem Seil hängenden Last aufweist, mit einer aktiven Seegangskompensation, welche durch eine Ansteuerung des Hubwerks die Bewegung des Seilaufhängepunkts und/oder eines Lastabsetzpunktes aufgrund des Seegangs zumindest teilweise ausgleicht, und einer Bedienersteuerung, welche das Hubwerk anhand von Vorgaben des Bedieners ansteuert, wobei die Aufteilung mindestens einer kinematisch beschränkten Größe des Hubwerks zwischen Seegangskompensation und Bedienersteuerung einstellbar ist.
