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. Call Cliff or Karen to information.
Free Standing A-Frame
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
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.
RANSOME HEAD & TAIL STOCKS
Ransome headstocks and tailstocks, with capacities of 2,500 lbs. and up, are
designed to rotate large frames, heavy structures or rollers for maximum down
hand welding, overlay or hard-facing operations. These simple, rugged machines
can help your operation reduce labor costs, increase product quality, minimize
operator fatigue and minimize downtime.
Headstocks are power-driven and equipped with specially designed gear ratios for
safety. Tailstocks are similar in construction to headstocks, but are
non-powered with a free-wheeling table. Tailstocks are also usable with welding
positioners for minimum tooling expense on short run jobs.
Ransome headstocks and tailstocks are manufactured with all-steel, heavy-duty
welded construction. All electrical components are enclosed and protected with
low voltage push-button stations for maximum safety. A reversing starter is
furnished for the rotation drive.
Headstock and tailstock tables are slotted for quick clamping of weldments,
while positive gearing assures minimum backlash.

RANSOME MANIPULATOR WELD HEAD
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.
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
True automatic welding
requires the use of a manipulating device which brings the welding head to the
MANIPULATOR TRAVEL CARS

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 concrete industry.
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 work-pieces – 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 the future.
