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
MANIPULATOR TRAVEL CARS
Ransome offers two styles of Manipulator Travel Cars. They include a manual push car and a series of variable speed travel cars. The manual car rides on
track. The powered cars ride on machined rail track. The weight and gauge width of the machined rail tracks vary depending on the load capacity required.

RANSOME COMPANY HISTORY
Founded in 1895, Ransome Machinery Company joined a growing number of new
enterprises emerging out of the Industrial Revolution. The company quickly
gained a reputation for quality and engineering. By the turn of the 20th
century, Ransome was the premier producer of specialty machines for the booming
In 1932 Ransome Company made a significant strategic shift to focus on building
innovative products for automated welding applications. The process of arc
welding was a relatively new technology in those days, and welders were
constantly burdened with the task of having to shift and reposition workpieces –
some weighing many tons – as they were being welded together. Borrowing from its
successful concrete mixer design, Ransome created the world’s first welding
positioner – a significant breakthrough in efficiency, which allowed the welder
to easily reposition pieces for continuous down hand welding.
Demand for Ransome positioners grew rapidly, and the company’s product line
quickly expanded to meet the increasing needs of the industry. Ransome turning
rolls, manipulators and positioners provided state-of-the-art material handling
equipment to many American industrial giants. In 1943, Ransome became part of
the Worthington Corporation, and with the Second World War in full swing,
Ransome equipment was a common sight throughout many war plants. From small
benchtop positioners to gigantic automated manipulators, Ransome products
continued to build a reputation for quality that would follow the company into
