Hydraulic lifts are an efficient and safe solution for vertical transportation in low and medium-rise buildings. Its operation is based on physics principles that allow smooth and controlled movement.
Next, we will explain in detail the operation of hydraulic lifts, their types, safety, and aspects to take into account during their installation. If you are considering installing a hydraulic lift, this information will be very useful.
What are hydraulic lifts?
The hydraulic lifts They use the pressure of a fluid, usually hydraulic oil, to raise and lower the lifts cabin. Unlike electric lifts, which use a motor and pulley system, hydraulic lifts rely on a piston and cylinder to move the cabin.
This system is especially suitable for buildings with few floors due to its load capacity and energy efficiency.
Types of Hydraulic Lifts
There are several types of hydraulic lifts, each one designed to satisfy different needs and applications, here we discuss them in detail:
Conventional hydraulic lifts
These types of lifts use a piston that extends from the base of the well to the cabin. They are ideal for low-rise buildings and require a deep pit to accommodate the piston.
Pitless Hydraulic lifts
These lifts are designed for buildings where it is not possible to dig a deep pit. They use a telescopic piston system that allows lifting without the need for an extensive pit.
Double piston hydraulic lifts
On the other hand, this model of lifts uses two pistons to raise the cabin, providing greater stability and load capacity. They are suitable for taller buildings and industrial applications.
Operation of hydraulic lifts
Knowing the components and mechanical processes gives us a better understanding of how hydraulic lifts work. This is based on the hydraulic pressure generated by a pump that pushes oil into the cylinder, thus moving the piston and raising the cabin. Below, we describe the components and the process:
Main components
- Hydraulic pump: generates the pressure necessary to move the hydraulic fluid.
- Electric motor: powers the hydraulic pump.
- Cylinder and piston: The piston moves inside the cylinder under the pressure of the hydraulic fluid.
- Control valves: regulate the flow of hydraulic fluid to control the speed and direction of movement.
- Control unit: Manages lifts operations and ensures its correct operation.
The operation of hydraulic lifts is based on Pascal's principle, which states that pressure applied to a fluid confined in a closed system is transmitted uniformly in all directions.
In the case of hydraulic lifts, the pressure generated by the hydraulic pump is transmitted to the fluid inside the cylinder, pushing the piston upward. The piston, in turn, raises the lifts cabin.
To descend, the control valve releases fluid from the cylinder, allowing the piston to slowly lower by gravity. The rate of descent is controlled by regulating the flow of fluid through the valve.
Are hydraulic lifts safe?
The operation of hydraulic lifts is efficient and stable; they have control systems that ensure a smooth and controlled ride. This type of lift is especially suitable for applications where a high load capacity and precise movement are required.
The safety of hydraulic lifts is one of the main concerns of both manufacturers and users. Fortunately, these systems are designed with multiple safety features such as valve systems, sensors, alarms, rescue systems, and preventive maintenance to ensure smooth and accurate operation.
Below we discuss in detail the usefulness of these features for safety purposes during the operation of hydraulic lifts:
Safety valve system
Safety valves control the flow of hydraulic fluid and prevent uncontrolled movement of the cab. In the event of a system failure, these valves close automatically to stop the lift.
Sensors and alarms
Hydraulic lifters are equipped with sensors that constantly monitor the status of the system. If any problem is detected, an alarm is activated and the lift stops immediately.
Rescue systems
In the event of a power failure, hydraulic lifts are usually equipped with rescue systems that allow the car to be lowered manually to the nearest floor.
Regular maintenance
Regular maintenance is crucial to ensure the safety of hydraulic lifts. It is advisable to perform periodic inspections and follow the manufacturer's guidelines for preventative maintenance.
What to take into account when installing a hydraulic lift?
Installing a hydraulic lift requires careful planning and consideration of several key factors to ensure optimal and safe operation. Here are some important things to keep in mind:
Space evaluation
It is essential to evaluate the space available for the installation of the lift. This includes pit depth, ride height and engine room size.
Regulatory compliance
The installation of hydraulic lifts must comply with local and European safety regulations. It is important to ensure that the project is in compliance with all applicable regulations.
Lift type selection
Depending on the specific needs of the building, the appropriate type of hydraulic lift must be chosen. This may include conventional, pitless or double piston lifts.
Material quality
The quality of the components and materials used in the installation of the lift is crucial for its durability and safe operation. It is advisable to opt for high quality materials from recognized manufacturers.
