Disclosed is a maintenance enclosure (1) for use when maintaining a wind turbine blade (2). The maintenance enclosure (1) comprising a ceiling (3), a floor (4) and at least two side walls (5a, 5b) extending between the ceiling (3) and the floor (4). The maintenance enclosure also comprising a first adjustable opening (6) in a first side wall (5a) of the at least two side walls (5a, 5b) adapted for receiving the wind turbine blade (2) and a second adjustable opening (7) in a second side wall (5b) of the at least two side walls (5a, 5b) adapted for receiving the wind turbine blade (2). The first adjustable opening (6) and the second adjustable opening (7) are positioned opposite each other and the said floor (4) comprises a slit (8) extending at least a portion of the distance between the first adjustable opening (6) and the second adjustable opening (7). Also, the slit (8) is adapted for receiving the wind turbine blade (2). Furthermore, a method for maintaining a wind turbine blade (2) is disclosed.

The invention relates to an in-ground lifting system and corresponding method for lifting a vehicle. The lifting system includes one or more lifts including at least one moveable lift; a support structure for mounting the one or more lifts in a pit; a moving drive configured for moving the one or more moveable lifts in the pit; a lifting drive configured for lifting one or more of the lifts for raising and/or lowering the vehicle; and a cover configured for covering the pit. The cover includes a number of cover elements. An individual cover element extends in a width direction of the pit. The cover elements are configured to move between a pit covering state and a lift moving state such that the one or more moveable lifts pass over and/or by the cover elements. The cover elements move when one of the one or more moveable lifts moving through the pit is approaching.

A pit for containing a vehicle lifting apparatus is constructed from a plurality of precast concrete pieces and assembled in a trench. Conduit, plumbing, heating elements, and the like are cast into the pieces to facilitate safe construction/assembly of the pit. A lift apparatus is assembled or positioned in and at least partly attached to the pit. One or more mounting features are cast into and/or attached to the pit wall to help fix the lifting apparatus relative to the pit and/or to help fix the pit relative to a surrounding building.

The present invention relates to a modular pit structure for an inground lifting system. The pit structure includes: a first end part; a second end part; at least one intermediate part, wherein the at least one intermediate part has a length, a width and a height; and a frame configured to be placed in an assembled pit structure. After assembling of a pit, the length of the intermediate part extends in a substantially horizontal direction between the first and second end parts and an interlock between adjacent parts of the pit structure extends in a substantially vertical direction.
