Hydraulic cylinders have traditionally been the go-to solution for lifting loads over 3,000 lb. However, their associated equipment can be challenging to fit into tight spaces, despite their powerful performance. A more compact alternative is the electro-hydraulic actuator, which can manage loads up to 4,800 lb and achieve speeds of up to 4 inches per second. These actuators are clean, versatile, and offer relatively low lifecycle costs, matching hydraulic actuators in load handling and shock absorption. They are increasingly utilized in various heavy-duty applications across outdoor equipment, marine, military, aerospace, and more.
Automotive Lift Repair Tampa Florida Hydraulic cylinders require a complex assembly, including oil reservoirs, electric motors, pumps, filters, and valves, with the size of these components dictated by the desired speed and cylinder dimensions. As speed requirements rise, the costs and spatial demands of the entire setup also increase.
For instance, the Automotive Lift Repair Tampa Florida electro-hydraulic actuator is comparable in size to conventional electric actuators but delivers significantly more power. In these actuators, an electric motor rotates to pressurize hydraulic fluid, controlling its flow through valves for extension and retraction.
While electro-hydraulic actuators and hydraulic cylinders may be similar in size, the former needs far fewer components, providing a clear advantage in power density. Additionally, electro-hydraulic systems offer better cleanliness and safety, as hydraulic cylinders can leak at fittings, leading to oil contamination and slip hazards. Leaks in hydraulic components can also waste energy and reduce actuator speed.
For loads up to 4,800 lb, electro-hydraulic actuators outperform hydraulic cylinders in power density, maintenance, placement flexibility, cleanliness, and cost, while still effectively managing shock loads. They are self-contained and require no maintenance, unlike hydraulic cylinders, which need regular fluid servicing and can develop leaks as they age.
Automotive Lift Repair Tampa Florida Electro-hydraulic actuators allow engineers greater flexibility in design and placement, as they don’t require extensive support systems. This makes it easier to route electrical wiring instead of hydraulic lines, reducing overall system size and the risk of leaks.
Hydraulic cylinders excel at absorbing sudden shocks, such as when a plow encounters an obstacle. They instantly redistribute fluids to handle energy spikes. Electro-hydraulic actuators have comparable shock resistance.
In conventional designs, hydraulic systems may be most cost-effective when adding cylinders to an existing hydraulic setup. Otherwise, the expenses of additional support systems must be considered. Electro-hydraulic actuators simplify fluid handling and storage, leak management, and maintenance, ultimately reducing lifecycle costs for users and providing marketable advantages for OEMs.
An Automotive Lift Repair Tampa Florida actuator is a device that produces linear or rotary motion, relying on an input energy source like electricity or hydraulic fluid to function. This energy is transformed into mechanical movement, resulting in either a rotating shaft or an extending and retracting rod.
Essentially, an actuator converts energy into motion and finds applications in various fields, including robotics, industrial automation, transportation, and aerospace. Actuators can be categorized based on the type of energy they utilize, such as electrical, pneumatic, or hydraulic.
Common types include linear actuators, which convert rotary motion to linear motion, and rotary actuators, which do the opposite. Linear actuators are frequently used in industrial automation, robotics, and medical equipment, while rotary actuators are often found in valves, turbines, and pumps.

Automotive Lift Repair Tampa Florida Actuators can also be classified by the technology they employ:
– Electric Actuators: Powered by electricity, these can be further divided based on the type of motor used, such as DC motors, stepper motors, and AC motors.
– Pneumatic Actuators: These utilize compressed air and are common in industrial automation and robotics.
– Hydraulic Actuators: Operated by fluid pressure, these are typically used in heavy-duty applications, such as construction equipment and machinery.
The selection of an actuator depends on the specific application, considering factors like load, speed, and the operating environment.
Choosing the Right Actuator
When selecting an Automotive Lift Repair Tampa Florida electric linear actuator, several key characteristics must be considered: Stroke, Force, Speed, and IP Rating. Typically, you would prioritize Stroke first, followed by Force, then Speed, keeping in mind the trade-offs between speed and force. A high force often results in lower speed, while higher speeds may come with reduced force.
– Load Capacity: Ensure the actuator can support the intended load, considering its weight and any factors that might affect movement.
– Speed: Match the actuator’s speed to the application’s requirements, which may involve trade-offs with force and precision.
– Stroke Length: Choose an actuator with an appropriate stroke length for the required distance and any physical constraints.
– Force: Confirm that the actuator can generate sufficient force to move the load and overcome friction or resistance, which may require calculating the needed force based on load and desired acceleration or deceleration.
– Precision: Ensure the actuator meets precision requirements, considering factors like accuracy, repeatability, and backlash.
– Environmental Factors: The actuator should be capable of operating in its intended environment, accounting for temperature, humidity, and exposure to contaminants.
– Power Supply: Ensure compatibility with the available power supply and voltage requirements.
– Noise Level: Consider the acceptable noise level for the application.
– Control Options: Evaluate control options, such as manual controls, programmable controllers, and sensors, and choose the most suitable for the application.
By thoughtfully considering these factors, you can select an Automotive Lift Repair Tampa Florida electric linear actuator that fulfills the specific needs of your application, ensuring optimal performance and reliability.
Step 1: Determine the Required Stroke (Extension)
The stroke of an actuator, also referred to as its extension, is the distance the rod moves in and out. Typically measured in inches, stroke lengths can range from 1″ to around 40″. Actuators with strokes longer than 40″ to 50″ are uncommon due to mechanical limitations of the leadscrew that generates the pushing and pulling force.
Step 2: Consider the Required Speed
The speed of the actuator is influenced by the internal gear ratio. A higher gear ratio reduces the rod’s speed but significantly increases its force. Actuators can generate forces from just a few pounds to several thousand pounds. Increasing the size of the motor can also enhance both speed and force. However, keep in mind that larger motors may trade off speed for force.
