Precision Positioning

Rotary Positioners

We offer a full range of rotary positioners to meet all of your application needs.

• Position readout accuracy ±0.005 degrees
• Operational bending moment up to 1,355,818 Nm
• Maximum speed up to 6.6 rpm
• Large hole turns

Multi-Axis Rotary Positioners

A broad selection of performance, convenience, and protection options enable you to configure your positioner for your specific application.

• Position readout accuracy ±0.005 degrees
• Bending moment up to 406,745 kg
• Payloads up to 90,718 kg
• Maximum speed up to 3.0 rpm

Floor Slides

Floor Slides allow an entire stack of azimuth, elevation and other linear and rotary axis to be repositioned linearly on the range.

• Vertical load up to 32,700 kg
• Bending moment up to 192,500 Nm
• Standard lengths up to 7.3 m
• Position readout accuracy ±0.13 mm

Vertical Slides

The complete versatility of elevated or ground-level testing on a single test range can be achieved by incorporating the vertical slides. This flexibility is made possible through extended vertical carriage travel and ease of installation and adjustment of equipment on the tower.

• Position repeatability 1.13 mm
• Maximum carriage lifting capacity 454 kg

Cartesian Positioners

Linear position repeatability better than ±0.02 mm and planarity better than 0.025 mm RMS is offered in select models.

• As small as 0.3 m x 0.3 m motion area
• As large as 33 m x 16 m motion area
• Resolution (XY) ≈ 0.05 mm
• Maximum speed up to 0.76 m/s

Turntables

A broad selection of performance, convenience, and protection options enable you to configure your turntable for your specific application.

• Payloads up to 69,853 kg
• Diameter up to 21 m
• Position readout accuracy up to ±0.02°
• Capable of rotating cars, trailers, tanks, aircraft

Gimbals

The MEC-GIM gimbal offers extreme accuracy by virtue of its direct drive motors that are structurally coupled to the encoders and the antenna/ counterweight system.

Position Controllers

Our position controllers offer coupled, multi-axis control of servo and stepper motors and allow for encoder and laser interferometer feedback integration.

• Configurable for control of up to 8 axes
• Stepper or servo motors position control
• Encoder feedback capable
• Virtual axis capable
• Remote control capable
