Among the most powerful devices to handle heavy loads, the hydraulic scissor lifts are one of the most commonly used pieces of equipment in industries. Even though the workings of these lifts may seem complicated, the design and working is actually quite simple.
By getting to know how this equipment works can help you in better understanding its operations, while also letting you know which specific industries require these.
The two biggest advantages of using a hydraulic scissor lift table is that it ensures the safety of the employees and improves production times. It can elevate heavy items in both industrial and commercial environments.
Before taking a deep dive into how these hydraulic table scissor lift tables work, let’s take a look at its main components. These will allow us to better understand this equipment.
5 Main Components of a Hydraulic Scissor Lift Table
Even though looking at the hydraulic lift table seems complicated, in actuality it’s quite simple in both structure and design. Let’s have a look at the five key components of this apparatus:
- Base Frame
- Hydraulic Power/Motor Source
- Hydraulic Cylinders
- Scissor Mechanism
- Main Platform
Now that you know the main components, let’s get into the details and explain the function of each component.
Base Frame
The base frame, or also called the platform, serves as the structural foundation of the hydraulic scissor lift table. This part is responsible for supporting all the other components.
Its main purpose is to provide stability, ensuring that the lift remains firmly positioned on the surface/ground during operation. This is especially crucial when undertaking heavy items.
The base frame also houses or supports essential components such as the hydraulic power or the electric motor units and mounting points for the scissor arms. Its robust construction helps absorb operational stress and vibrations. This is critical to ensure safe and long-term use, especially when used for industrial purposes.
Hydraulic Power/Motor Source
As the name suggests, the Hydraulic power pack for scissor lift is the part responsible for providing the power required for the hydraulic scissor lift table to operate. It is the driving force for the entirety of the system, generating the required force through the hydraulic pump, electric motor and the fluid reservoir.
Hydraulic Cylinders
The lifting force is generated via the hydraulic cylinders to move the heavy loads placed on the lift table. The pressurized hydraulic fluid is pumped into the cylinder, building the required pressure to move the piston(s). This in turn brings the scissor mechanism into motion.
Scissor Mechanism
The scissor mechanism is on the receiving end of the force generated by the hydraulic cylinders. The crisscrossed arms come into motion and are responsible for raising or lower the main platform.
Main Platform
The main platform is the top most surface of the hydraulic scissor lift table. This is where anything that requires to be lifted is placed. It plays a critical role in evenly distributing weight during operation.
When the lift is activated, the platform moves vertically along with the scissor mechanism while maintaining balance and stability. Its rigid construction ensures that materials or equipment remain secure during lifting and lowering.
How Does the Hydraulic Scissor Lift Table Work
Let’s discuss how this contraption operates. The simple working principle of a scissor lift is based on a series of interconnected, cross-linked arms. These arms go through an expanding or contracting movement, resulting in the upward or downward movement of the main platform. Note that this main platform carries all the load.
To put it simply, when these arms open, the platform rises, and as the arms close, the main platform lowers. The force required to operate this mechanism depends on several factors such as:
- Size of the platform
- Height it needs to reach
- Weight of the load being handled
When it comes to industrial or commercial applications of the hydraulic scissor lift table, the operation depends on its power source. These can be from either of the following:
- Hydraulic
- Pneumatic
- Electric
- Diesel-powered
Regardless of which power source is installed, all types of lifts follow the same core lifting principle. For the hydraulic scissor, the process initiates when the operator activates the system, allowing hydraulic fluid to flow into the cylinders through controlled valves.
Once activated, the system directs pressurized fluid from the reservoir into the hydraulic cylinders. This pressure forces the cylinder piston to extend outward, which pushes the scissor arms apart and raises the platform.
When the platform is to be lowered, the operator releases the pressure by opening a control valve, allowing the hydraulic fluid to return to the reservoir.
As the pressure goes down, the scissor arms gradually retract, bringing the platform back down in a controlled and smooth manner.
Types of Hydraulic Scissor Lifts Used in Construction

Hydraulic Scissor Lifts
Hydraulic scissor lifts operate using pressurized hydraulic fluid to raise and lower the platform. The system works by increasing or decreasing fluid pressure within the cylinder, which drives the lifting mechanism.
These lifts are known for their simplicity and ease of operation, making them a practical choice for many standard lifting tasks. However, their performance can be affected by temperature changes depending on which area they are being operated. This is because the hydraulic fluid tends to thicken in colder conditions.
An important point to note is that they are best suited for applications where smooth and controlled lifting is more important than speed or high power output.
Electric Scissor Lifts
Electric Scissor LiftsElectric scissor lifts are powered by batteries and are widely preferred for indoor applications. They operate quietly and do not emit fumes, making them suitable for enclosed environments such as warehouses, retail spaces, and maintenance facilities.
Their compact design allows them to move easily in tight spaces, improving maneuverability and efficiency.These lifts are commonly used for tasks like equipment maintenance, installation work, and indoor material handling.
Diesel Scissor Lifts
When it comes to requiring raw power for lifting the heaviest of loads, the diesel-powered scissor lifts are the way to go. They are ideal for construction environments where high power and durability are required.
These machines are capable of lifting heavy loads to significant heights and are designed to handle demanding conditions. Because they run on diesel fuel, they produce noise and exhaust emissions, making them unsuitable for indoor use.
Their strong build and large platforms make them ideal for large-scale construction projects and heavy-duty applications.
Pneumatic Scissor Lifts
Pneumatic scissor lifts use compressed air instead of hydraulic fluid or fuel to operate. This makes them an environmentally friendly option, as they do not produce harmful emissions.
They are suitable for both indoor and outdoor use, especially in areas where cleanliness and sustainability are priorities. However, they typically offer less lifting power compared to diesel or hydraulic models.
These lifts are often used in specialized environments where reduced environmental impact is important.
Rough Terrain Scissor Lifts
Rough Terrain Scissor LiftsAs their name suggests, rough terrain scissor lifts are specifically designed for outdoor use on uneven or challenging surfaces.
They are equipped with heavy-duty tires, enhanced stability features, and high load capacities to operate safely in difficult conditions.
These lifts can handle slopes, rough ground, and harsh weather, making them ideal for construction sites and industrial outdoor projects.
Their robust design ensures reliable performance where standard lifts may struggle.
Common Types Of Hydraulic Scissor Lifts
Here are five of the most common types of hydraulic scissor lifts that are used in both commercial and industrial applications, more specifically in construction.
They are as follows:
Single Scissor Lift Table
A single scissor lift table is the most commonly used design, featuring a single set of crossing arms that support the platform. It is suitable for applications requiring moderate lifting heights and stable vertical movement.
When the hydraulic system is activated, the arms extend to raise the platform smoothly, making it ideal for use in warehouses, workshops, and production lines where simple lifting tasks are performed efficiently.
Double Scissor Lift Table
A double scissor lift table is built with two layers of scissor arms stacked vertically. This allows it to reach greater heights compared to a single scissor design.
This is possible by increasing the hydraulic pressure, allowing both sets of arms to extend in sequence, resulting in the platform getting lifted higher. All this is achieved while maintaining balance and support.
The double scissor lift table is often used in environments where additional elevation is needed, such as maintenance operations, loading docks, and industrial facilities.
U-Type Scissor Lift Table
A U-type scissor lift table is specially designed for handling palletized loads. The platform for this particular machine is shaped like a “U”. This allows the pallet trucks to easily position loads onto the lift without requiring a ramp.
The hydraulic mechanism raises the platform while keeping the load stable. This is one of the most practical solutions for industries and commercial businesses to utilize at their warehouses and logistics centers. This allows for quick and frequent pallet handling of essential items.
Low Profile Scissor Lift Table
As the same suggests, the low profile scissor lift table is specifically designed with as low of a height as possibly required. This allows loading all kinds of heavy or light items to be loaded directly from the ground level. This eliminates the need for pits or additional lifting equipment.
Despite its compact design, it uses a hydraulic system to lift loads in an efficient and safe manner. It is particularly useful in packaging lines, assembly stations, and environments where there is less space to operate.
Mobile Scissor Lift Table
When lifting is required on the move, a mobile scissor lift table is the one to go for. It combines lifting capability with portability by incorporating wheels into its base. This allows it to be easily moved between different work areas.
This type of hydraulic scissor lift table allows for a smooth lifting, while the mobility feature makes it highly versatile for tasks that require both transport and elevation of materials.
It is commonly used in workshops, maintenance operations, and dynamic industrial settings.
