摘要:
A method for erecting a structural tower comprises: providing a plurality of tower sections; engaging a translatable crane assembly with a lower one of the tower sections; engaging a second one of the tower sections with a cable operatively engaged with the translatable crane assembly; hoisting the second one of the tower sections towards an upper end of the lower one of the tower sections; securing the second one of the tower sections to the lower one of the tower sections; and translating the translatable crane assembly vertically along the secured tower sections towards the upper end thereof. There is also provided a wind turbine assembly.
摘要:
The device has a support (8) sliding along a mast (1) on parallel guide rails (9, 10) allowing a crane-support assembly (6) to move along the mast by a lifting unit. The assembly is connected to a hoist (11) of the unit by a cable (12) passing on a pulley. The cable is passed on another pulley when the hoist is placed outside. Blocking units has plates projecting from periphery of the support. The plates are equipped with holes aligned one to another when the support come across mast`s top to receive locking rods. The blocking units, holes and the rods allows the assembly in the mast`s top. An independent claim is also included for a method for rapidly disassembling of a rotor and a nacelle of a mast of a windmill.

Crane for the assembly of wind turbines and assembly procedure, the former consisting of a central structure (1) which may be mounted around the tower (2) of the wind turbine and provisionally locked onto it at any height, with an assembly formed by a jib (4) and a counter-jib (5) configuring a tilting rotary unit with respect to the structure (1) and including their respective winches (6 and 8), by means of which the whole of the crane may be hoisted to a higher position and the components comprising the wind turbine may be raised to the position of assembly.
摘要:
A crane (28) is rotatably mounted on a base (26) which includes a jacking mechanism (30,32,38) adapted to surround and engage an upright foundation column for vertical adjustment thereon. A supporting leg of a self-elevating mobile marine platform is suitable for use as such a column for supporting the crane.

A hanging concrete distribution mast, which can rise along the wall of the building, is provided. The hanging concrete distribution mast includes a pillar (2), support frame (5) and an arm (3). The support frame (5) sheathes outside the pillar (2). The arm (3) is provided on the top of the pillar (2). A foot boom (1) is provided on the bottom of the pillar (2). The support frame (5) and the foot boom (1) are fixed to the wall (10) of the building by a fixer (9).
摘要:
The invention relates to an arrangement for conveying concrete for the construction of multi-storey concrete buildings. The arrangement comprises a concrete-distributing mast which is height-adjustable on completed parts of the building, for example on storey floors (48', 48'', 48'''), said mast comprising a supporting column (10), a rotary unit (12) and an arm assembly (14) preferably designed as an articulated boom, and said mast being equipped with a conveying line (16) which is guided over the height of the supporting column (10) to the arm assembly (14) and which is supplied with liquid concrete. To facilitate the handling of the concrete-distributing mast during transportation and during the climbing operation, the invention proposes that the supporting column (10) has at least one channel-shaped surface depression (36, 38) extending in the longitudinal direction of the column, in which depression can be sunk that part of the conveying line (16) which extends over the supporting column (10), and/or an elongate part of the climbing apparatus (52).
