    • A gantry crane (10) is configured in a panel turner application. The gantry crane (10) generally includes a gantry crane structure (14) having a first cross-beam (28) and a second cross-beam (30). A first main hoist mechanism (40) and a first auxiliary hoist mechanism (42) are coupled to the first cross-beam (28), and a second main hoist mechanism (44) and a second auxiliary hoist mechanism (46) are coupled to the second cross-beam (30). The crane (10) includes a hydraulic system configured to reduce the lift capacity of the first and/or second main hoist mechanism (40, 44), and to equalize the hoist capacity between the first and second main hoist mechanisms (40, 44) or the first and second auxiliary hoist mechanisms (42, 46) in certain applications. The auxiliary hoist mechanism (42, 46) are configured for powered movement along the respective cross-beams (28, 30).
    • 龙门起重机(10)配置在面板转盘应用中。 龙门起重机(10)通常包括具有第一横梁(28)和第二横梁(30)的龙门起重机结构(14)。 第一主起重机构(40)和第一辅助起重机构(42)联接到第一横梁(28),并且第二主起重机构(44)和第二辅助起重机构(46)联接到 第二横梁(30)。 起重机(10)包括液压系统,其构造成减小第一和/或第二主起重机构(40,44)的提升能力,并且使第一和第二主起重机构(40,44)之间的提升能力相等, 或第一和第二辅助提升机构(42,46)。 辅助起重机构(42,46)构造成沿着相应的横梁(28,30)动力移动。
