Actuator Systems for Modern Wheelchairs

Both older people and people with disabilities want to maintain a mobile and comfortable lifestyle regardless of the healthcare system. Expanding their capabilities is the key issue, and with the help of modern electric wheelchairs, it is possible to live an independent life like never before. With the help of electric linear actuators, it becomes possible to create a multifunctional electric wheelchair with all the following benefits.

  • Reliable and thoroughly tested technology.

  • Low noise movement.

  • Compact design.

  • Linear motion performance warranty from automation manufacturer.

What is Wheelchair Linear Actuator

Wheelchair users are heavily dependent on their chairs in everyday life. As a rule, users of wheelchairs want to live a normal life without the constant help of their relatives and the assistance of specially-trained medical workers. Electric actuators create a movement and provide a very reliable use of the automated wheelchair, which can minimize the disability inconveniences. All functions, from adjusting the height of the chair to optimizing the position of the legs support system or changing the position of the back of the chair, help improve wheelchair ergonomics.

In order for the wheelchair actuator to respond correctly to the surrounding conditions and user commands, it needs a control unit. The control unit connects the actuator, the remote control, as well as the auxiliary control processor into a single system. Progressive Automations offers a wide range of linear actuator control units of various types. This manufacturer can provide the control units designed to work with one or two actuators, as well as its actuators can be connected into complex systems that can be controlled by microprocessors like Raspberry Pi and Arduino that can control six actuators at once

Ways to Use Wheelchair Actuator

Wheelchair lift actuators are used to adjust the position of the backrest, seat, and footrest. This adjustment allows disabled people to control their comfort and stay in position wanted using the hand and foot remotes. 

Taking into consideration the fact that for the medical actuators, the basic principle is the safety priority, all of the electric wheelchair actuators have to be able for the emergency lowering function. Actuators with two engines, telescopic lifting columns and many control systems can solve this problem. The linear motion automation products of Progressive Automations comply with the International Electrotechnical Commission (IEC 60601) technical standard and provide a long service life.

Linear movement automation solutions provided by the linear actuator for wheelchair allow upgrading wheelchair with a seat lift, back adjustments, leg place adjustment, etc. The use of this technology for wheelchairs allows ensuring optimal positioning taking into account the physical parameters of the user; weight, height, and even length of limbs. 

Actuator Systems for Wheelchairs and Their Advantages

Electric actuators have many advantages. The most obvious of them are almost silent movement and smooth coordination of movement between actuators. An electric wheelchair actuator that is able to provide positional feedback is compatible with other control units and can provide a safer and more efficient movement. The compact design of the actuator systems used for wheelchair automation means that actuators can be used in a limited space, which provides freedom of design while maintaining ergonomics and comfort in wheelchairs. Sometimes linear actuators are even used for adjusting wheelchair lighting systems. With the help of mini linear actuators builds in the wheelchair, a person driving this means of transport can regulate the angle of the lighting system choosing the most appropriate.

Another advantage of the implementation of the linear actuators for construction of wheelchairs is that this linear motion automation technology can be powered by the alternating current power source. This makes the use of actuator-based wheelchairs not just as easy as the use of ordinary wheelchairs but far more convenient. 

Actuators Types Used in Wheelchairs

Due to the limited amount of space, wheelchair construction demands the implementation of only small types of linear actuators, that, nevertheless have to be able to lift significant loads. As a matter of fact, actuators used for wheelchair construction are also called medical actuators. They are electromechanical actuators specially designed for use in various medical equipment. They must withstand extreme conditions while working smoothly and quietly, be safe and hygienic. The medical actuator does not fundamentally differ from the usual one, but it uses special materials and technological solutions. During cleaning, they may be exposed to high-pressure jets of water and caustic cleaners. These medical actuators, usually are made with protection classes up to IP66 (dustproof casing and protection against powerful water jets, which is especially important when cleaning medical furniture and appliances). Thus, actuators for medicine in terms of basic characteristics (load, speed) are similar to universal ones, however, in terms of noise, protection, and safety, they have special requirements and, characteristics. The special attention is given to the linear actuator implementation safety measurement. Protection against injuries is ensured by such options as a safety nut, a manual drive, the function of releasing the rod, work only on the extension. The use of electrical remotes may be undesirable because of the danger of electric shock when a wire is damaged, so pneumatic or wireless remotes are usually more desirable to use.

Why Use PA Linear Actuator for Wheelchair?

Each Progressive Automations product is thoroughly tested before release. This is done not only to comply with the requirements of international medical regulations, but also to make it easier for manufacturers to meet modern strict testing standards for wheelchairs.

When using products of Progressive Automations, customers can be sure that they obtain products of the manufacturer with many years of professional experience in the sphere of linear motion automation. All this experience along with talented engineering specialists of the PA team allows this manufacturer to regularly improve the quality and reliability of the technologies released and spread through the global automation market. Electric linear actuator solutions of this manufacturer for wheelchair construction turn the whole construction into high-tech tools for disabled and elderly people. There are various needs and requirements, especially when it comes to such an important and complicated means of transport as an automated wheelchair. 

The company carefully takes into consideration all customers' wishes and tries to make its products as precise and reliable as possible. Moreover, as the global automation leader and author of innovative linear motion automation solutions, the Progressive Automations team strives to contribute to market demands and needs. A global presence on the world stage means local attention to markets around the world and the support of its customer audience is always important for the company. That is why all company products are always relevantly tested and can be used for such a careful and demanding purpose as actuator motorized wheelchair construction.

Actuators are widely used in medicine solving both simple and quite complex tasks, which increase the requirements for such parameters of the actuator as its speed, effort, and controllability. There are many examples of linear motion actuators implementation in medicine these are positioning of laser medical devices, adjustable hospital furniture like medical chairs and electric beds, hospital equipment like lifts and patient carriers, surgery equipment - operating tables, pendant ceiling consoles, lights, ophthalmology equipment - devices for eyesight checking, exercise machines - for rehabilitation and sports, and finally electric wheelchairs for disabled and elderly people.
