Compact, economical, quiet: The new TARVOS linear actuators from ALLTEC Antriebstechnik

Heilbronn/Kissing, Germany, 27 July 2009 – With the new linear actuators from its TARVOS series, ALLTEC Antriebstechnik of Heilbronn, a subsidiary of the Pfaff-silberblau Group with headquarters in Kissing, is rounding off its product range in the lower and mid-level capacity categories. These newly introduced electromechanical actuators provide economical solutions for applications requiring lower load capacities of 100 N (22.5 lbs) to 2000 N (450 lbs). Due to their reliability, and to the fact that they operate nearly silently, the compact yet robust TARVOS actuators are highly versatile and suitable for uses ranging from special-purpose industrial machinery to vehicle manufacturing and shipbuilding all the way to applications in furniture making and medical device technology. Robust under all conditions In the standard configuration, ALLTEC Antriebstechnik’s TARVOS actuators, which are designed for pushing/pulling applications, are available with load capacities from 100 N (22.5 lbs) to 2000 N (450 lbs). These closed drive systems feature high-quality machining: The die-cast gear housing is made of zinc, the outer and inner tubes are made of aluminum, and the gear drive is metal. Thanks to these features and to the electromechanical design, the TARVOS actuators can also be employed in all kinds of climatic conditions with little or no maintenance required. With their protection rating of up to IP 66, temperatures between -25 and 65° C do not inhibit the drives’ ability to function, nor does splash water. As a result, they are also well suited for outdoor applications. High-performance DC motors (12V, 24V and 36V) supply steady and reliable power. Economical, quiet and safe TARVOS actuators make it possible to design motion sequences more directly and efficiently in a wide variety of applications, thus reducing costs. In the packaging industry, for example they can be used to make format adjustments, to open and close flaps, doors and drawers or to raise and lower components. In addition, the systems run so quietly that they can be employed in health care equipment and home furniture for adjusting the position of treatment tables and arm-chair backrests. Another outstanding feature offered by the new actuators from ALLTEC Antriebstechnik is their ability to absorb static forces, even when the power supply drops off, because no pneumatic components are used: This excellent safety feature is made possible by a self-locking acme screw and an internal limit switch. The range of applications for the TARVOS series is as broad as the spectrum of positive characteristics that the devices offer: The TARVOS TA 2, for example, is designed for a maximum capacity of 1000 N (225 lbs), and thanks to its very small dimensions, it is superbly suited for adjusting the guides for materials handling equipment. Its “big brother,” the TARVOS TA 4, on the other hand, can handle loads of up to 2000 N (450 lbs), yet operates very quietly. That makes the device ideal for use in machinery and automation technology as well as in air conditioning and ventilation systems. As optional extras, the new TARVOS actuators are available with different sensors, such as potentiometers, REED contacts, or Hall effect sensors. Depending on customer requirements, they can also be delivered complete with a controller and operating devices.
