Electric lifting cylinders Manufacturers online

Electric lifting cylinders, also known as electric linear cylinders or electric cylinders, are mechanical devices that convert electrical energy into linear motion.

These drives are popular in many applications as they can be precisely controlled and offer high efficiency.

Below you will find the structure and function of electric lifting cylinders, their areas of application and their advantages:

Structure and mode of operation:

A typical electric lifting cylinder usually consists of the following main components:

1. Electric motor: The motor drives the movement. It can be a direct current (DC) or alternating current (AC) motor.

2. Gearbox: The gearbox reduces the speed of the motor and increases the torque required to move the load.

3. Spindle or threaded rod: This component converts the rotary motion of the motor into linear motion. There are different types of spindles, such as ball or trapezoidal thread spindles.

4. Push rod: The push rod is connected to the screw and moves linearly when the screw rotates.

5. Housing: The housing protects the internal components and provides a mounting structure.

6. Limit switches and sensors: These are used to monitor the position and movement of the actuator and ensure that it is not operated beyond its physical limits.

Applications of electric lifting cylinders:

Electric lifting cylinders find application in a variety of industries, including:

1. Automation technology:
For precise motion control in manufacturing equipment.

2. Medical technology:
In hospital beds, wheelchairs and other medical devices.

3. Aerospace:
For controlling aircraft flaps and other moving components.

4. Automotive industry:
For applications such as seat adjusters and tailgates.

5. Agriculture:
In machinery for seed distribution, harvesting and other agricultural processes.

6. Manufacturing and mechanical engineering:
Automated handling and positioning of components.

Advantages of electric lifting cylinders:

• They allow precise control of position and speed.
• Compared to hydraulic or pneumatic systems, they require less maintenance.
• They only consume energy when they are in motion.
• There is no risk of fluid leaks, as is the case with hydraulic systems
• They can be easily integrated into existing control systems, especially systems that already work with electrical signals.

Here are the most important aspects to look out for when buying an electric lifting cylinder:

There are several important aspects to consider when buying an electric lift cylinder.

• The lifting cylinder must have sufficient force to lift or move the required load. Pay attention to the rated force (in newtons or kilonewtons) that the device can move.
• For applications that require continuous or frequent use, the cylinder should be designed for continuous loads.
• Pay attention to the maximum speed at which the cylinder can move a load. This is particularly important in applications where time is of the essence. Note that speed is often related to load capacity: with heavier loads, the speed may decrease.
• In some cases, it may be useful to be able to adjust the speed of the cylinder to the application.
• The stroke length indicates how far the cylinder can extend. Select a length that is sufficient for the desired application.
• Some models allow flexible adjustment of the stroke length.
• Pay attention to the precision of the movement. For applications that require high precision, choose electric lifting cylinders that allow fine and exact positioning.
• Modern lifting cylinders offer various control options such as integrated limit switches, positioning sensors or connection to control systems (e.g. PLC).
• The motor should provide enough power to move the load with the desired speed and force. Pay attention to the voltage (e.g. 24V, 48V, 230V) and the power consumption of the motor.
• Depending on the application, choose between a direct current (DC) motor, an alternating current (AC) motor or a stepper motor for precise movements.
• Make sure that the lifting cylinder is easy to install and fits the existing mounting points. Standardized mounting brackets or holes make installation easier.
• The physical size of the cylinder must fit into the available installation space. Take into account both the retracted and extended state.
• Pay attention to the protection class of the cylinder (e.g. IP65 for dust and splash water protection), especially if the cylinder is used in harsh or damp environments.
• The lifting cylinder should be designed for the operating temperatures, whether in cold or hot environments.
• Find out about the service life of the cylinder, usually specified in the number of cycles. A high-quality lifting cylinder should withstand many operating cycles.
• Choose cylinders that are low-maintenance or can be easily serviced. Simple lubrication and replacement of wearing parts should be possible.
• Electric lifting cylinders should have limit switches to protect the cylinder from overload and mechanical damage.
• Integrated overload protection ensures that the motor is switched off if the load is too high or blocked.
• Ensure a good warranty period and technical support, especially for complex applications.

When purchasing an electric lifting cylinder, factors such as lifting force, speed, stroke length, precision, protection class and drive are decisive. A suitable model should be adapted to the specific requirements of the application to ensure reliable and long-lasting performance. Manufacturer quality and ease of maintenance also play an important role in the selection process.
