Abstract: A machine includes a frame, ground-engaging elements coupled to the frame, and a hoisting system having a sideboom and a fairlead. The hoisting system also includes a hook pulley block and a hoisting cable extending through the fairlead and the hook pulley block and held in tension such that the hoisting cable couples pivoting of the fairlead to pivoting of the sideboom. The pivotable fairlead may be instrumented with position, cable loading, and cable feed sensors.

Abstract: An upper turning body mounted on a lower body for a crane includes a turning frame mounted on the lower body to turn freely and a boom provided to the turning frame to be raised and lowered freely. The turning frame includes a pair of attachment brackets to which a base end section of the boom is attached such that the boom is free to be raised and lowered, and a main frame to which the pair of attachment brackets are provided with an interval in the left-right direction of the upper turning body. The dimension of the main frame in the front-rear direction of the upper turning body orthogonal to the left-right direction is smaller than the dimension of the main frame in the left-right direction.

Abstract: A load line guide is configured to direct a load line of an crane along a boom assembly, the load line guide comprising a guide housing and a first guide cam. The guide housing presents a gap oriented in a lateral direction and a channel oriented in a longitudinal direction. The first guide cam is pivotably secured to the guide housing and disposed in the gap. The first guide cam is configured to be selectively placed into an open position and a closed position. While the first guide cam is in the open position, the load line guide is configured to receive the load line into the channel of the guide housing; and while the first guide cam is in the closed position, the guide housing is configured to retain the load line guide within the channel of the guide housing.

Abstract: A system for transporting and testing a crane includes a crane, a transporting frame and a foundation. A first connecting mechanism is provided for establishing a releasable connection between the crane and the transporting frame. A second connecting mechanism is provided for establishing a releasable connection between the transporting frame and the foundation. In a starting state, the crane, the transporting frame and the foundation are separate from one another. In a transporting state, the crane is connected to the transporting frame. In a testing state, the crane is connected to the transporting frame and the transporting frame is connected to the foundation. The invention also relates to a corresponding method. The invention makes it possible for the crane to be assembled, and tested, at a site remote from an offshore wind turbine.
