Efficient and precise welding depends on the right positioning.Preston-Eastin positioners are designed for precise, safe operation. Drive system mechanisms and electrical controls are configured to protect the operator.

Precision spur gears, driven by worm gear reducers, provide minimum backlash with maximum strength and longevity. A worm gear drive prevents the load from moving unless the worm is driven. Preston-Eastin positioners feature a four-post base for vertical adjustment on modelsPA-15 and larger.

Preston-Eastin recently added a power tilt option to the PA-5, one of the most popular models.

In addition to the standard models, Preston-Eastin will custom design positioners to meet the customer’s needs.

Designed for many years of low maintenance operation.Preston-Eastin headstock and tailstock positioners are designed for many years of low maintenance operation. Headstocks provide powered variable speed rotation in either direction controlled with a remote pendant. Units are ideal for welding, flame-cutting or cladding operations.

Tailstock positioners have the same specifications as the corresponding headstock positioners, except they are not powered.

Due to variation in process requirements, Preston-Eastin head and tailstocks are configured and constructed specifically for each customer’s application.

Preston-Eastin. Your single source for high quality floor turntables.Preston-Eastin floor turntables provide a high-precision, low-cost method of rotating a workpiece around a vertical axis. They provide powered rotation in either direction at adjustable speeds controlled from a remote pendant Turntables are ideal for welding, flame cutting, flame-spray, grinding, X-ray or drill press positioning.

Rotational power is provided by a DC variable-speed motor, AC variable frequency drive or AC servo. Pendant controls are labeled FORWARD, STOP, REVERSE, RAPID and SET. Table rotation is maintained until stopped by the operator.

Preston-Eastin floor turntables are rated for maximum workpiece weight and off-set from the axis of rotation. Normal primary electrical input is 115/220/440 VAC, 60 hertz depending upon the size of the turntable.

Due to variation in process requirements, Preston-Eastin floor turntables are configured and constructed specifically for each customer’s application.

Preston-Eastin’s turning rolls help turn precision into productivity.Preston-Eastin turning rolls are designed and constructed to afford the customer many years of safe and dependable operation.

To ensure precise alignment at all center-distance settings, these products have machined and jig-drilled frames. Rubber-tired rollers absorb shock during loading and cushion the load during welding. A steel overload disc (models TDRA-5 and larger) protects the rubber tires from excessive overloads. We also offer optional steel, urethane or phenolic tires.

Final drive gearcase is totally enclosed and constructed entirely of steel. Aluminum-bronze worm gears provide maximum strength and durability to the final drive.

A remote pendant with 30-foot cord provides the operator with all functions for welding, forward/reverse, start/stop, weld/rapid, and potentiometer for precise speed adjustment. DC motor and controls up to TDRA-30HD, AC variable frequency drive on larger.

Increase output while decreasing fatigue.Preston-Eastin manipulators are versatile tools applicable to a wide range of operations, and are compatible with any make head or welding process. They may be located over a workpiece to perform manual welds or can be integrated into automated welding processes. Among the many benefits are reduced operator fatigue, precision, waver-free welds, and uninterrupted welds of extended duration at distances far greater than an operator can reach.

Preston-Eastin welding head manipulators are designed for many years of low maintenance operation. Smooth operation of vertical and horizontal movement is assured with heavy-duty roundways and adjustable bearing mounted hardened rollers.

Limit switches are installed to prevent overtravel. The remote-control pendant operates on 115 VAC for operator safety.

Manual or powered travel cars are available for all Preston-Eastin manipulators.

Travel CarsTravel cars, either manual or powered, expand the operational capabilities of manipulators for pipe spools, pressure vessel, pole production or any type of production where the part length exceedsthe normal operational reach of the manipulator. Travel cars can be supplied with v-groove or industrial rail wheels. Standard configurations in manual or powered operation depend on the size of manipulator to be mounted.
