发明名称 HOISTING DEVICE
摘要 <p>A hoisting device includes a hoisting cable, a winch, a crown block and a traveling bottom block provided with a load attachment device. Both the crown block and the traveling bottom block include one or more sheaves having an essentially horizontally extending rotation shaft about which sheaves the hoisting cable is reeved. At least some of the traveling bottom block sheaves are associated with a releasable connector, and are thereby detachable from the load attachment device and displaceable to an inoperative position. The rotation shaft of multiple traveling bottom block sheaves and multiple crown block sheaves is essentially perpendicular to the rotation shaft of remaining multiple traveling bottom block sheaves and remaining multiple crown block sheaves.</p>
