RANSOME MANIPULATOR WELD HEAD DIRECTOR

Ransome Welding Manipulators are the most versatile pieces of equipment associated with sub arc automatic welding, offering the precision of even the most highly skilled welder but with even greater consistency. Ransome manipulators can be designed or programmed to duplicate the same procedure without variation, as well as weld sequentially different procedures on the same weldment. They can be adapted to operate in pick and place application, as well as plate burning, painting and arc gouging.

Ransome welding manipulators offers eight basic manipulator models in a variety of sizes and capacity ranges. Each can be customized for specific applications such as simple straight line or circumferential welding. Custom designs for extra long reach and extra heavy loads are also available, as well as a telescoping boom option when space is limited. All Ransome manipulators are available as pedestal mounted motorized or fixed boom machines and can be mounted on a free standing base or motorized travel carriage for mobility.

When do you need a Ransome column and boom?

When welding large plate sections or long seams
When the piece or part is of a thickness that would require multiple passes with hand-held methods When penetration and bead shape must be uniform throughout the entire weld length When extreme close tolerance of arc gap or speed of travel is required When the ability to increase profit through the use of an automatic welding head becomes practical

Why use a weld manipulator?

Automatic welding systems are designed to be mounted on a rigid structure and move from seam to seam, providing a higher degree of accuracy and consistent repeatability over manual methods

True automatic welding requires the use of a manipulating device which brings the welding head to the work

RANSOME FLOOR TURNTABLES

Ransome floor turntables are available with variable or constant speed drives, as well as non-powered rotation. Many variations in speeds, control, table size and configuration, and overall height are available. Standard turntables are available in capacities from 250 lbs. to 120,000 lbs. Larger capacities are available by special order.

Ransome turntables offer two basic floor turntable designs as a standard

Free Standing A-Frame Design

Ransome A-frame weld turntable has a hollow spindle featuring pre-loaded roller bearings. The motor and reducer mounts are built into the bearing housing and main support beam, and floor-mounted by means of A-frame assemblies at each side. This design allows all mechanical components to be housed under the table with no protrusions. A-frame turntables are available for capacities of 250, 500, 1,000 and 2,500 lbs.

Free Standing Center Column Design

Designed for capacities over 2,500 lbs., the Ransome free standing center column turntable has no spindle and uses slewing ring bearings. This combination provides uniform support of the load and eliminates the problems of spindle and table deflection. The rotation gear is machined on the outer race of these huge bearings to provide smooth table rotation without binding or vibrating.

The bearing is completely self-contained. The bearing assembly bolts to the center column and the table bolts to the bearing, making table replacement or special fixturing very simple. Because there is no spindle, the table can be placed on any flat surface for layout or fixture installation. The direct drive feature requires minimal maintenance and provides less backlash. It also eliminates overhung loads on the drive motor output shaft and gear reducer input shaft. Center column turntables have a plain faced table.
