ABSTRACT:
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).
