Trust, Quality, Excellence
The PA-240 HD12 positioner by Preston-Eastin is designed and built for precise and safe operation. Drive system mechanisms and electrical controls are configured to protect the operator. Precision spur gears, driven by worm gear reducers, minimize backlash while providing 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 models PA-15 and larger.
