RANSOME POSITIONERS

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 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.

RANSOME TURNING ROLLS

Ransome vessel turning rolls are used across a broad range of industries to simplify the fabrication, assembly and inspection of tanks, drums, pressure vessels and cylinders of all sizes. Ransome offers both standard and special turning roll designs to satisfy virtually any application.

Ransome tank turning rolls improve the safety, efficiency and productivity of both automatic and manual welding by minimizing handling and the need for crane services. They allow complete control of forward or reverse rotation roller over and smooth variable speed to provide optimum speed control and eliminate undesirable production variability.

Ransome vessel, tank and pipe turning rolls offers capacities from one to 300 tons. Custom designs can handle up to 1,200 tons.

Specially designed tank roll over for better shock absorption and seam cushioning, without sacrificing load carrying capacity. Durable Ransome tank turning rolls are the industry premier welding turning rolls

Ransome 85 durometer tires, 20 points higher than standard, provide greater load carrying capacity, along with greater heat and tear resistance 
Available high-strength machined steel rollers for high temperature and heavy load applications

Adjustable roller spacing to handle small or large diameter work pieces Combination steel and bronze worm wheel resists shock from heavy loads. Self-aligning, anti-friction bearings for smoother running power and idler rotation Lowered drive heights for easier loading and unloading rolls from either end Simple operation, with forward, reverse, rapid travel and speed variation over the entire speed range

Options:

Constant center (manually adjustable or powered)

Variable or constant speed

DC or frequency drives

Sub-bases

Travel carriages

Tachometer (digital or analog)

Synchronization for multiple rolls working together.

TURBINE TURNING ROLLS - TURBINE  ROTATORS

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 EXTERNAL SEAM WELDERS

Internal-external seam welders are cantilevered from one end, which allows part loading and unloading of open part sections onto the mandrel arm. The mandrel support clamp includes isolation from the mandrel to the pressure beam assembly to guard against magnetization.

ENGINEERED SEAM WELDING MACHINES

Ransome Company manufactures all seam welders in our own facility, completely Made in the USA.  Our longitudinal  seam welding machines are built to our customers specific requirements. Seamers from 4 foot to 12 feet are currently available.

3 O'CLOCK TANK WELDER GIRTH WELD SEAMERS - AUTOMATIC VESSEL WELDING

The AGW straddles the tank shell plates, riding on serrated steel drive wheels that can be adjusted for tank diameter. The adjustable A-frame telescopes manually to handle six- to 10-feet high steel plates.

The AGW’s operator platform is a sturdy and solid work station with guard rails and all-weather curtains for operator safety and comfort. Ransome’s double platform is fully equipped with its own direction and speed controls. An access ladder allows movement to the primary flux separator tank and to the side of the dual unit.

WELDING CHUCKS - PIPE GRIPPER CHUCKS

SLIDES & SWIVELS

Slides manufactured by Ransome have extremely fluid motions with ample weight capacities. Pandjiris has two basic models, one with 1 inch round ways and the other with 1-1/2" round ways.

These quality slides compound nicely and are interchangeable as vertical or horizontal slides. Protective boots, various lengths and motorized slides are all available as standard options.

Ransome slides are considered by many to be the best quality slides on the market today because of their compactness, large weight capacities and smooth fluid movements.

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.
