Abstract
A crane includes a crane structure defining a substantially vertical rotation axis; a boom connected with a first end to the crane structure to be rotatable about the vertical rotation axis; a trolley moveable along the boom in longitudinal direction of the boom; a hoisting cable and a load connector. The load connector is arranged at a free end of the hoisting cable to be connected to a load for hoisting purposes. The trolley includes a cable guide to guide the hoisting cable and an attachment configured to temporarily attach the load connector to the trolley to fix the position of the load connector relative to the trolley.
Claims14
A crane configured for hoisting a wind turbine blade held in a horizontal orientation in a frame during the hoisting, the crane comprising:
- a crane structure defining a substantially vertical rotation axis;
- a boom connected with a first end thereof to the crane structure so as to be rotatable about said vertical rotation axis along with the crane structure;
- a trolley that is mounted moveable along the boom in a longitudinal direction of the boom;
- a hoisting cable;
- and
- a load connector,
- wherein the load connector is arranged at a free end of the hoisting cable and is configured to be connected to a frame holding a wind turbine blade held in a horizontal orientation in a frame during hoisting,
- wherein the trolley comprises:
- a cable guide configured to guide the hoisting cable;
- and
- an attachment configured to temporarily attach the load connector to the trolley in order to fix a position of the load connector relative to the trolley;
- wherein the load connector comprises a sheave block, and wherein the attachment forms a cavity in which the sheave block is received upon hauling in the hoisting cable.
