  • Publication number: 20150163989
    Abstract: A towable agricultural implement having a center section and foldable wings mounted by hinges on opposite sides of the center section to fold upwardly or downwardly about substantially longitudinal hinge axes. Each hinge has a spaced ball joint and guide roller in roller slot. A wing float axis for each wing extends substantially perpendicular to the longitudinal hinge axis in a transverse direction, each wing also being pivotal about the float axis. The hinge design with the float axis prevents weight transfer between the center section and wing sections when the implement operates over uneven soil, providing uniform soil conditioning over the width of the implement. The center section rollers are positioned ahead of, behind, or co-linear with the wing rollers. Lockout kits are provided for mounting within the roller guide slots for restricting motion.

  • Patent number: 8863882
    Abstract: A hydraulic steering actuator system for a forklift with front and rear sections includes a hydraulic steering motor. The forklift front section includes a mast mounting a pair of fork blades and a pair of wheels. The forklift rear section mounts a pair of drive wheels. The forklift front and rear sections are connected by an articulated connection with a vertical rotational axis. The steering actuator motor driveshaft extends along the vertical rotational axis. First and second actuator mounting brackets are connected to the forklift front and rear sections respectively. One of the mounting brackets includes upper and lower locking assemblies locking the hydraulic steering motor driveshaft whereby torque applied to the steering motor is transmitted to the articulated connection for turning the forklift front section relative to the forklift rear section. The range of motion is preferably 180°-205° for accommodating side-loading operations from relatively high storage shelves.

  • Publication number: 20140262368
    Abstract: A fully-integrated tillage implement including two modes of transportation: a working implement mode and a transportation mode, wherein a transport wheel assembly can be hydraulically raised and lowered at will to transform the implement between the various positions. A hydraulic leveling bar affixed to the drawbar assembly serves to keep the entire implement level with the tractor while traversing a field or while towing the implement in transport mode.

  • Publication number: 20140054051
    Abstract: A tillage implement with raisable soil-leveling reels includes a main frame, which can include a center section and wing sections hingedly connected to the center section. The wing sections are adapted for being hydraulically rotated and raised from generally horizontal field positions to transport/storage positions. Gangs of earth-working tools, such as coulter discs or tines, are mounted on the wing sections. The soil-leveling reels are mounted on trailing arm assemblies, which are adapted for raising and lowering the reels between raised, transport/storage positions and lowered, field-engaging positions. Hydraulic piston-and-cylinder units are connected to compression springs and adapted for raising and lowering the arm assemblies and the reels. The compression springs absorb and dampen jolts and impacts from field irregularities and transport motion-induced forces, thus protecting the piston-and-cylinder units.

  • Patent number: 8434657
    Abstract: A multi-station, gantry-based automated welding system includes a gantry mounting robotic arc welders or other equipment. The gantry has a range of travel over multiple workstations, each workstation being adapted for rotatably mounting a respective workpiece on a headstock assembly and a tailstock assembly, which define a workpiece or weldment rotational axis extending therebetween. The tailstock assembly can be located at different positions within a workstation for accommodating different lengths of workpieces. Encoders are installed at the moving elements of the system for precisely tracking and providing output to the computer controller. Primary and secondary power/data distribution systems include cable and hose carriers for providing mobile power/data connections to the gantry and also to the robotic arc welders mounted thereon. The power/data distribution systems are elevated above a facility floor to avoid interfering with equipment, personnel and activities at floor level.

  • Patent number: 7992650
    Abstract: An implement with a ground working tool mounted on an arm pivotably movable between raised and lowered positions includes a pneumatic down pressure control system. The down pressure control system includes upper and lower mounts with an air spring located between them and having compressed and extended configurations with said arm raised and lowered respectively. A parallel plate mechanism maintains the upper and lower mounts in parallel relation and maintains a relatively consistent down pressure of the air spring. Multiple air springs can be provided on an implement and pneumatically interconnected by an air line for simultaneously charging to a constant air pressure.
