There are three main types of linear actuators for adjusting massage tables. Each one works well for different changes that the table needs to make quickly. Knowing these differences helps professionals pick the right one for their tasks.
Electric actuators boost effectiveness by automating movements with buttons. A handheld remote or panel allows users to make smooth, precise changes in table height or position with minimal effort. This is especially useful in busy settings requiring rapid, varied adjustments.
Hydraulic actuators use fluid to enable strong and steady movements. They are good for heavy tables or where a lot of strength is needed.
Users turn a crank to move these actuators, offering precise control. This type does not rely on power or fluid. As a result, it is good during power outages. Cranking the table adjustments helps maintain services without long breaks. While it requires more physical effort, it gives therapists control over the changes.
In industrial domains, the factors that go into choosing linear actuators often change. Curiously, this is based on what jobs the actuators need to manage and the settings in which they will operate.
The coefficient of friction determines how smoothly the actuator operates in different conditions. A lower coefficient allows smoother movement. This smooth movement can reduce wear on both the actuator and the table over time. In industries where cleanliness is crucial.
For instance, hospitals or high-end spas, actuators with low friction are preferred. They help maintain a gentle, reliable motion that does not damage the equipment.
Some industries require temperature-resistant hydraulic actuators. For example, in places with heat-generating machinery or outdoor services, the actuator may be exposed to extreme heat. If the actuator cannot handle this heat, it may warp or fail, leading to several problems.
That is why the material needs to survive heat for a long time without degrading. This durability ensures that the massage tables remain dependable for longer without requiring frequent repairs. This need makes it essential for businesses to keep operating smoothly.
Industries with a high demand for precision and heavy loads, such as medical facilities, have more need of high-functioning actuators than operators in other spaces. In these situations, the tables must smoothly and exactly change from one position to another. This feature ensures patient comfort and safety.
Furthermore, businesses that have specially made tables built to hold more weight than average have a greater need for actuators with enhanced load capacity because they must service more clients than usual.
Stroke Length
The stroke length determines how far the table can adjust. Most massage tables have a stroke length of about 10-15 cm, allowing for height and angle adjustments.
Load Capacity
This is the same as saying that the actuator must support the weight of the table and the client. Electric actuators handle 100 kg to 150 kg, while hydraulic ones can manage 300 kg or more.
Power Supply
Electric actuators frequently operate on 12V to 24V DC power, which is easy to install. This feature makes it easy and efficient to adjust the table in a massage room. However, hydraulic actuators usually need more power.
Noise Level
Noise level matters for the function of the massage table. No one wants to hear loud noises when they are getting a massage, so the actuator used has to be quiet. Electric actuators make less noise than hydraulic ones. Electric ones make about 30dB to 40dB of noise, while hydraulic ones make about 60dB to 70dB of noise.
Speed
Most clients prefer a slow, smooth massage table movement, so the table does not move too quickly. Electric actuators move at 5 to 20 mm per second. This speed is ideal because it allows the adjustments to be made slowly and calmly. However, hydraulic actuators move faster, at 20 to 30 mm per second.
To put an electric actuator on a massage table, first, the actuator should be fixed to the base and top sections of the table. Next, the electric parts must be connected to a power source, such as a battery or plug outlet.
Then, the control system, which may be a remote or button, needs to be linked to the actuator. This system controls the movements of the actuators. After everything is in place, one should test the table to ensure all adjustments work smoothly.
A linear actuator for a massage table is easy to use. If it is an electric actuator, one uses a remote or buttons to adjust the table. The user just has to press the right button to raise or lower the table or tilt it in the right direction.
This makes it easy to find the right position for each client. When using a hydraulic actuator, the user must apply less effort to turn the knobs. Mechanical actuators need the therapist to move the table by hand. This action helps keep the work balanced.
Clients want a relaxing experience, so the table should have a soft, pleasant feel. Electric actuators are better for soothing clients because they move silently. However, hydraulic actuators are stronger and can move heavier things, but they are often loud.
Electric actuators need less work to keep them running than hydraulic ones. Cleaning the electric parts is very rare. On the other hand, the hydraulic parts require frequent cleaning. Brushes clean the electric parts. Oil or fluids are needed to keep the hydraulic parts running smoothly.
Clients want to know that their massage table will work as it is meant to. That is why accuracy is critical. Electric actuators give very precise changes in table height or angle. This accuracy makes clients feel good because they do not have to worry about whether the table will move incorrectly.
Hydraulic actuators are strong but not as precise as electric ones. Detailed movements can sometimes lead to uneven surfaces on the table. This unevenness would make the massage table uncomfortable for the client. Electric actuators cause an overall smoother surface on the table. This feature is perfect for giving the client a relaxing experience.
The quality of the materials that make up the actuator influences how long it lasts. Electric actuators with steel rods last longer than those with plastic parts. Hydraulic actuators with steel rods also last longer. However, they require more work to keep them running smoothly. Plastic parts wear out quickly, making the actuators less useful.
Client Safety
Client safety is very important when using linear actuators. Sometimes, the actuator makes the table dip. This dipping can hurt the client's back or neck. It can also make the client slide off the table. The good news is that electric actuators are better at keeping the table level. This leveling helps stop accidents.
Emergency Stop
An emergency stop is important, too. What if something goes wrong, and the remote or buttons do not work? There needs to be a way to stop the actuators from moving. That is why the emergency stops on electric actuators are very useful. They help prevent injuries during these rare situations.
Load Limits
Every kind of actuator has a limit on how much weight it can lift. Moving more weight than this limit can break the actuators. It may also damage the table and hurt the person on it. Always check these load limits before using the table.
Cables and Hydraulics Maintenance
Electric actuators use cables to pull pieces. These cables can sometimes get tangled or broken. A tangled cable can cause the table to tip over, which can injure the client.
Meanwhile, hydraulic actuators use liquids that often leak. These leaks can make floors slippery and lead to falls. Checking for damage and fixing it quickly is vital to keep the workspace safe.
Yes, the kind of massage will help determine which actuator to use. For example, light massages do not need heavy-duty actuators. They can get by with electrical ones. However, deep tissue or hydro massages need stronger hydraulic actuators.
Other important factors include the budget, the space where the table will be used, and the weight limit the table must hold. All these factors help decide which actuator is best for the table.
One common mistake is not paying attention to weight limits. Each table and actuator has a limit that must be respected. Using a table with an actuator that is too weak for its burden will cause the table to bend or break. This problem may also cause the actuator to fail.
Another mistake is focusing only on price. It can be tempting to buy a cheap actuator to save money. However, cheap ones wear out quickly. They may also not work as well as more expensive ones.
Hydraulic actuators require more work to keep them smooth and clean than electric ones. A cleaning schedule should be set for them based on how much they are used. In addition, the fluid levels should be checked, and any leaks fixed as soon as they are found.
