  • Patent number: 8985274
    Abstract: A mobile platform has a separate and independent linear actuator pivotally connected near each opposite end of the platform where there is a contact limit switch that when triggered by contact with the side of a flatbed, stops movement of the actuator, and thus stops movement of the platform, toward the side of the flatbed. Because each of the two actuators is pivotally connected to its respective end of the platform and moves independently of the other, each end of the platform can stop moving toward the flatbed before or after, depending on how the flatbed is misaligned, the other end of the platform stops moving toward the flatbed. In this way the platform self-aligns to the alignment of the flatbed and avoids the need to reposition a flatbed that is not precisely aligned parallel to the central axis of the loading bay.

  • Patent number: 8800717
    Abstract: Mobile scaffolding units include a vehicle for movement across ground surface, a stationary platform rigidly fixed to the vehicle at a predetermined immovable height above the ground surface, and a gantry platform operatively connected to the stationary platform for movements between a retracted position where the gantry platform is nested adjacent to the stationary platform, and an extended position wherein the gantry platform extends laterally outwardly from one or another lateral side of the stationary platform to provide an operator on the gantry platform an extended horizontal reach laterally of the vehicle. The mobile scaffolding units allow an operator to work at elevated heights and with lateral reach in one area of a work zone (e.g., to trim roadside vegetation) and then move to another area of the work zone without requiring an operator to dismount from the gantry platform.

    Abstract: Fall protection for personnel servicing an elevated work area from a man lift. A bridge is pivotally mounted to a working edge of the man lift. The bridge pivots between a stored position and a substantially horizontal operative position. The bridge has a pivotally mounted edge, a remote edge opposite to the pivotally mounted edge and opposed sides. An expandable enclosure is anchored to the man lift. The enclosure is movable between a collapsed position and an expanded position. In the collapsed position, the enclosure is collapsed parallel to and provides fall protection along the working edge of the man lift. In the expanded position, the enclosure provides fall protection for the opposed sides of the bridge in the operative position and provides fall protection in the work area by enclosing a portion of the work area beyond the remote edge of the bridge.

  • Patent number: 7869923
    Abstract: In an excavator equipped with an offset boom, an offset command value generating device of a rotation control device offsets a second boom arranged on a distal end side in a rotation direction relative to a first boom arranged on a proximal end side when an acceleration start judging device judges that a rotation operation is started, and offsets the second boom in a reverse rotation direction when a deceleration start judging device judges that a rotation deceleration operation is started. Accordingly, when a rotation acceleration is performed using a reaction force generated in the offset, clearances between members of a work machine can be contracted in advance in the rotation direction, while when the rotation deceleration operation is performed, these clearances can be contracted in advance in the rotation reverse direction, thereby reducing an impact in the acceleration and deceleration.

  • Patent number: 6547034
    Abstract: A pruning vehicle having characteristics specifically utilizable in an orchard having rows of trees opposite each other. The vehicle is equipped with two platforms side by side which can be adjustably located vertically and horizontally in a plane perpendicular to the direction of the vehicle's motion. Each platform is controllable by an operator standing upon the platform through foot pedals incorporated thereon. Platforms are elevated above the vehicle by lifting structures designed to keep the platforms level to the ground at all times. The platforms are connected to a frame of the vehicle at a low slung central portion of the frame for added stability. Wheels of the vehicle are of a thin disc shape. Each wheel can slice through soft surfaces such as mud to attain a firm foundation for the pruning vehicle. Fins and teeth on the wheels provide added traction. Mud deflectors on the wheels prohibit mud from climbing up too high onto or bogging down the pruning vehicle.
