Abstract

A towable soil pulverizer 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 pulverizer operates over uneven soil, providing uniform soil conditioning over the width of the pulverizer. The center section rollers are positioned ahead of, behind, or co-linear with the wing rollers. Lockout kits are provided for mounting in the roller guide slots for restricting motion.

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 generally 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, e.g. in narrow-aisle warehouses.

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.

Single pass ground driven tiller and seeder apparatus

Abstract

A single pass ground driven tiller and seeder apparatus includes a support frame, an elongated drive rotor journaled transversely on the frame, a tillage assembly pivotally connected to the frame and formed by a pair of rearwardly extending bearing plates and having an elongated tillage rotor journaled thereto and extending transversely therebetween, and a firming roller journaled between mounting plates pivotally connected to the bearing plates. The drive rotor is rotated by ground contact as the apparatus is drawn along by a tractor. The drive rotor is drivingly engaged with the tillage rotor so that the tillage rotor rotates at a faster speed than the drive rotor. A seed metering mechanism is supported on the frame and deposits seed in front of the drive rotor. The tillage rotor breaks the soil and incorporates the seed into the soil, after which the firming roller firms the seed bed.

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.
