UTTING, POSITIONING & WELDING EQUIPMEN KOIKE ARONSON RANSOME The Most Complete Line in

How to Size Head & Tailstocks Weight Capacity The basic Head and Tailstock configuration includes (1) Powered rotation Headstock and a companion Non Powered Tailstock. The Headstock supports one end of the work-piece and imparts rotational motion to the work. The Tailstock merely supports the other end of the work- piece as it rotates. The first factor in selecting a HTS is to determine the maximum weight capacity required. The load should be evenly distributed between the Head and Tailstock, if either supports more than half of the load, (determined on CG location along the rotational...

Fixed Height Piloted tables for centering Full length table slots Chassis mounted weld current grounding blocks Low voltage hand control 50:1 Variable speed drives Koike Aronson / Ransome manufactures Head and Tailstock Positioners with a wide range of capacities and options. These units are a strong and simple solution for the rotation of long elliptical work pieces. When used together, they require much less floor space than a Gear Driven Positioner of similar capacity. Head and Tailstock Positioners can be used like a lathe to maintain rotation around the horizontal axis. High quality...

Constant Centerline, Steel wheels, Tachometers, foot controls and special engineered designs available. Ball Screw Elevation The Powered Elevation design makes maximum use of proven commercially available components, both in the elevation and rotation Elevation is by means of commercial Ball screw jacks for high duty cycle operation and driven by a worm/wormgear arrangement. The elevation axis uses two of these screw jacks for redundancy, coupled together and driven by a common motor. Belts, chains, and transfer gears are no longer utilized in the design. Guidance is provided by means of...

In many applications long weldments may be quickly mounted to 180° Tilters instead of setting up the intricate mounting often required for Head 90 degree tilt from the horizontal position assures accessibility for down-hand or flat welding while keeping the ends of the weldment open and 180° Tilters operate in a single range of motion and are uniquely suited for many applications. The Positioners also require much less floor space than other positioning products. • Optional table rotation • Optional geared elevation models Standard hand pendant provided with all models KOIKE ARONSON, INC. /...

Skyhook Positioners The Skyhook series Positioner provides 2-axis motion, continuous rotation and ± 180° tilt from the horizontal table position. This configuration of Positioner can also be made in a Geared Elevation version with a third powered axis for elevation. The worktable's surface can be specified at varying distances below the tilt axis, as well as specifying swing radius clearances from the table's rotation axis to the nearest obstruction. Due to the configuration of these models, it is necessary to consult the factory for sizing and capacity requirements. The counter balancing...
