How the actuator reduces physical strain

Imagine working in a laboratory where you have to open and close a soundproof hood several hundred times a day to take measurement samples. By evening, you feel like you've been lifting weights for 8 hours straight. Such a significant physical strain quickly leads to exhaustion and illness-related absences - a comfortable and employee-friendly solution looks different.

Protecting and relieving employees

That's why the American manufacturer Novascan Technologies, one of the leading companies for innovative products in the research field, has now come up with a clever solution that protects, relieves, and prevents workplace accidents.

Smart solution - executed simply

One of these is this soundproof hood, weighing a hefty 200 kg, which is easily opened and closed 100 times or more per day in everyday operation. Here's how Novascan solved this problem: Two linear actuators from GROB Antriebtechnik move the soundproof hoods quickly and silently.

What technology is behind it?

Two actuators from the FD series, each with a maximum load of 3,000 N, ensure a smooth and precise movement of the hood. Built-in limit switches prevent the actuator from extending beyond the set endpoint and being damaged. The two electric cylinders operate synchronously and can be easily and comfortably operated by the operator with the included manual control.

Fact Sheet

Actuators from the FD series can withstand maximum loads of up to 6,000 N. Typical use cases include:

Fast and precise positioning tasks in packaging machines, conveyors, or lifting tables, opening sluice gates, container lids, and ventilation flaps.

FAQs about Linear Actuators

There are mechanical, electromechanical, direct electric linear actuators (linear motors), as well as hydraulic and pneumatic linear actuators. We utilize electromechanical actuators in our drive solutions.

Which types of linear drive technology there are - GROB GmbH chevron_right

Electric linear drives use electrical energy for motion, whereas hydraulic and pneumatic drives use fluids or gases. Electric drives are more precise and efficient.

No, the MINI and linear cylinders are complete systems and cannot be expanded with other motors.

The IP66 classification indicates that the actuator is dust-tight and protected against strong jets of water. Ideal for applications requiring robust protection.

A linear actuator converts rotational motion into linear motion. It is powered by electric motors. However, linear movements can also be achieved through hydraulic or pneumatic actuators. Electric linear actuators are used for more precise movements.

Actuators with IP66 are suitable for harsh environments such as industrial settings, outdoor use, or applications requiring water cleaning.

The IP66 protection class significantly reduces the ingress of dust and water, minimizing maintenance requirements. However, regular inspection is advisable.

For the spindle end, the standard range offers options including threaded end, articulated head, ball joint head, flange plate, bearing flange plate, and pin. You can find corresponding dimensions in the General Catalog 2023 (grob-antriebstechnik.de)

Typically, it's an electric linear drive. It consists of three main components: spindle, motor, and gearbox. When a signal is received, the motor converts electrical energy into mechanical energy, moving the gears of the gearbox. These rotate the spindle, causing the spindle nut to move outward or inward.

Linear actuators are ubiquitous: in homes, offices, hospitals, factories, agricultural settings, and many other places. In hospitals and medical centers, you'll find linear actuators used to adjust patient tables, hospital beds, or operating tables. Other applications are in industry, agriculture, construction, and industrial automation.
