Patent number: 9302891Abstract: 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).Type: GrantFiled: September 14, 2012Date of Patent: April 5, 2016Assignee: Marine Travelift, Inc.Inventors: Jerry J.

Patent number: 6634305Abstract: A seed planting system for planting seeds in dirt in the depressions of a flat. The seed planting system includes a plurality of seeding assemblies each having a hopper. The hopper is designed for holding the seeds. Each of the seeding assemblies has dispensing portion. The dispensing portion is coupled to the hopper of an associated one of the seeding assemblies whereby the dispensing portion is designed for dispensing seeds from the hopper of the associated one of the seeding assemblies into the depressions of the flat. A regulating assembly is coupled between the hopper and the dispensing portion of each of the seeding assemblies whereby the regulating assembly is designed for regulating the rate at which the seeds are dispensed from the hopper to the dispensing portion of the associated one of the seeding assemblies.Type: GrantFiled: April 12, 2002Date of Patent: October 21, 2003Inventor: John E.
