A jack-up crane (1) and methods of installation and operation thereof. The jack-up crane is adapted to be lifted from the ground to the nacelle (2) or tower (46) of the wind turbine (3) by operating a cable winch (9) arranged at the ground (10) and to be operated at its installation position on the nacelle or tower by operating the same cable winch. The cable extends from the hook group (6), outwardly through the base (4) of the crane, from the nacelle or tower to a cable winch at the ground. The jack-up crane is provided with a cable crawler (11) having at least one motor-driven traction pulley (122) adapted to transmit tension to the cable (8) by friction during operation of the jack-up crane. The cable crawler is switchable between an active state (13), in which the traction pulley can transmit tension to the cable, and a passive state, in which the traction pulley cannot transmit tension to the cable.
一种自升式起重机(1)及其安装和操作方法。自升式起重机适于通过操作布置在地面(10)处的缆索绞盘(9)而从地面被提升到风力涡轮机(3)的机舱(2)或塔架(46),并且适于通过操作相同的缆索绞盘而在其位于机舱或塔架上的安装位置处被操作。缆索从吊钩组(6)延伸,穿过起重机的基座(4)向外延伸,从机舱或塔架延伸到地面处的缆索绞盘。自升式起重机设置有缆索爬行器(11),该缆索爬行器具有至少一个马达驱动的牵引滑轮(122),该牵引滑轮适于在操作自升式起重机期间通过摩擦将拉力传递给缆索(8)。缆索爬行器能够在主动状态(13)和被动状态之间切换,在主动状态下,牵引滑轮可向缆索传递拉力,而在被动状态下,牵引滑轮不能向缆索传递拉力。
