A modular jib crane for a nacelle for a wind turbine, the modular jib crane comprising:
- a base element for attaching the crane to the nacelle;
- a pillar, wherein said pillar is couplable with said base element at a first end of said pillar;
- a first crane arm, wherein said first crane arm is coupleable with said pillar at a first end of said first crane arm;
- and,
- wherein at least one of said pillar and said first crane arm includes a plurality of modules configured to be coupleable with each other to form said pillar or said first crane arm.
A modular jib crane kit for assembling a modular jib crane having a base element for attaching the crane to the nacelle, a pillar, a first crane arm, and a second crane arm, the pillar being couplable with the base element at a first end of the pillar, and, the first crane arm being coupleable with the pillar at a first end of the first crane arm, the modular jib crane kit comprising:
- a multitude of base elements, wherein each of said multitude of base elements is configured to mate with a different type of nacelle;
- a plurality of pillar modules configured to form different types of the pillar in dependence upon the type of the nacelle;
- and,
- at least one of a plurality of first crane arm modules and a plurality of second crane arm modules configured to form different types of at least one of the first crane arm and the second crane arm in dependence upon the type of nacelle.
A nacelle for a wind turbine, the nacelle comprising:
- a modular jib crane having a base element for attaching the crane to the nacelle;
- said modular jib crane further having a pillar, and a first crane arm;
- said pillar being couplable with said base element at a first end of said pillar;
- said first crane arm being coupleable with the pillar at a first end of the first crane arm;
- wherein at least one of said pillar and said first crane arm includes a plurality of modules configured to be coupleable with each other to form said pillar or said first crane arm;
- and,
- said base element being fixed to a support structure inside the nacelle.
A method for installing a modular jib crane including a base element for attaching the crane to the nacelle, a pillar, and a first crane arm, the pillar being couplable with the base element at a first end of the pillar, the first crane arm being coupleable with the pillar at a first end of the first crane arm, and, at least one of said pillar and said first crane arm including a plurality of modules configured to be coupleable with each other to form said pillar or said first crane arm, the method comprising:
- lifting a transport system including a basket configured to carry the plurality of modules to the nacelle, wherein the basket of the transport system carries the crane in a disassembled state;
- and,
- unpacking the basket and assembling the plurality of modules.
A maintenance system for a nacelle for a wind turbine, the maintenance system comprising:
- a crane configured to carry and to move a component inside the nacelle;
- a high-capacity hoist configured to move the component through a nacelle opening along a tower of the wind turbine;
- and,
- a carrying system configured to carry and to move the component between a region of the nacelle in which the crane is located and a region of the nacelle which includes the nacelle opening.
A method for maintenance of a nacelle for a wind turbine with a maintenance system including a crane, a high-capacity hoist, and a carrying system, the crane being configured to carry and to move a component inside the nacelle, the high-capacity hoist being configured to move the component through a nacelle opening along a tower of the wind turbine, the carrying system being configured to carry and to move the component between a region of the nacelle in which the crane is located and a region of the nacelle which includes the nacelle opening, the method comprising:
- moving a component with the crane;
- transferring the component between the crane and the carrying system;
- moving the component with the carrying system between the region of the nacelle in which the crane is located and the region of the nacelle including the nacelle opening;
- and,
- operating the high-capacity hoist in order to move the component through the nacelle opening along the tower of the wind turbine.
A method for installing a maintenance system including a crane, a high-capacity hoist, and a carrying system, the crane being configured to carry and to move a component inside a nacelle, the high-capacity hoist being configured to move the component through a nacelle opening along a tower of a wind turbine, the carrying system being configured to carry and to move the component between a region of the nacelle in which the crane is located and a region of the nacelle which includes the nacelle opening, the method comprising:
- providing a carrying system inside the nacelle;
- lifting a high-capacity hoist to the nacelle with an on-board hoist, wherein the high-capacity hoist includes a higher weight capacity than the on-board hoist;
- lifting the crane in a disassembled state to the nacelle with the high-capacity hoist;
- and,
- assembling the crane inside the nacelle.
