The design of Positech’s hydraulic industrial manipulator, the Taurus Positioning Arm (TPA), emulates the movement of the human arm. This hydraulic manipulator* allows for reaching in and under. It is able to maneuver over or around work cell obstructions. When the handling process requires precise positioning of heavy payloads, up to 2,500 pounds, the Taurus hydraulic system makes it the ideal choice. Safe, low-voltage, variable speed controls can be hand held, machine mounted on ergonomically designed controls stations. The Taurus is available in four model configurations, providing 64 inches of vertical lift and flexible mounting options.

check-zoom Advantages

  • 5:1 design factor minimum on all structural components
  • Pilot operated lock valve on lift cylinder and gripper cylinders prevent downward arm movement and loss of payload if supply pressure is interrupted
  • Parallel linkage arms allow the end-effector and the payload to remain parallel and level to the floor
  • Floor mounted pedestal provided with concrete anchor bolts, mounting hardware and leveling jacks for ease of installation (No grout required)
  • Low-voltage signal on all operator’s controls
  • Overload sensors prevent lifting more than machine capacity
  • Optional temperature sensors shut down system automatically to prevent overheating
  • Motor runs only when a handling function is activated

graph-zoom Performance

  • Up to 60,000 inch pounds of moment loading at the end of second arm for extended reach payload applications
  • Optional electric collector ring available for continuous main post rotation
  • Standard flange mounting for adaptability to a variety of custom end-effectors
  • Precision bearings and thrust washers at rotation axes for smooth motion and long life
  • Vertical axes brakes available
  • Adjustable drag brakes at each vertical axis of rotation
  • Infinitely variable up/down vertical speeds; easily adjustable minimum/maximum speed controls
  • Self-contained power unit
  • Vertical lift provided by single action hydraulic ram cylinder
  • Designed for minimal deflection
  • Mounting Options: overhead, trolley, pedestal or mobile/portable base
