Please click the " Read Article " button to listen.

The 200kg hydraulic elevator is a type of elevator that is currently attracting a lot of customer interest due to its safety and stability. Furthermore, this type of elevator is particularly suitable for houses with small areas but still want to install an elevator. Let's explore the details of hydraulic elevators with THANGMAYNIDEC in the article below.

What is a 200kg Hydraulic Elevator?

A 200kg hydraulic elevator is a type of mini elevator with a load capacity of 200kg. Unlike cable-driven elevators, hydraulic elevators operate using a mechanism that utilizes an oil pump system to create pressure to push the elevator cabin up and down. As the oil pressure increases, the piston moves vertically, thereby pushing the cabin up and down vertically.

Which types of buildings are suitable for a 200kg hydraulic elevator?

The 200kg hydraulic elevator is the smallest elevator on the market today, making it suitable for buildings such as:

• Renovated homes: 200kg hydraulic elevators can be easily integrated into stairwell spaces or narrow corners thanks to their advantage of requiring only a shallow pit or no pit at all and no machine room.

• For townhouses and subdivided houses with small floor areas: The minimum elevator shaft area is small (approximately 900mm x 1000mm for a standard cabin type), helping to maximize construction space savings.

• Mini villas and townhouses with 2-5 floors: Hydraulic elevators can be installed for 2-5 floors, meeting the need for smooth, comfortable, and luxurious movement for smaller families.

• Overhead height restrictions (OH): Hydraulic elevators do not require a high top floor height like cable-driven elevators.

Structure and Operating Principle of a 200kg Hydraulic Elevator

Hydraulic technology is widely applied in the manufacturing of tractors, forklifts, automobiles, aerospace, and industrial production lines. Today, hydraulic technology continues to develop and is effectively applied in the field of elevator drives, especially in ultra-compact elevator systems using hydraulic technology.

Structure of a 200kg Hydraulic Elevator

• Central control panel: The central control panel is installed outside the elevator shaft, at the lowest floor, with a maximum distance of 7m. Inside the panel are the following main components:

• Motor: The pump that generates the thrust force on the piston, allowing the elevator to move up and down smoothly.

• Hydraulic oil reservoir: This is where lubricating oil is stored, serving both as a pressure-generating fluid in the cylinder and to help machine parts operate more smoothly.

• Control system: Responsible for controlling all elevator operations to ensure they run smoothly, accurately, and as intended.

• Hydraulic valve system: Helps fluid flow in the correct direction to the required locations.

• Hydraulic piston: The hydraulic piston is the component that directly acts on the elevator cabin to create the elevator's movement. This component typically has a maximum length of 18m, a diameter of 100-200mm, and a pipe diameter of 5mm.

• Mechanical system: The elevator's mechanical system includes components such as the cabin frame, guide rails, guide shoes, landing doors, etc. These components work together to ensure the elevator moves in a straight line without deviating from its intended path.

• Elevator cabin and shaft frame: These are the parts that directly facilitate user movement. These components are interconnected to ensure safety and convenience throughout the ascent and descent.

Operating Principle of a 200kg Hydraulic Elevator

Hydraulic elevators operate based on thrust from hydraulic fluid (usually oil). Learn more about the operating principles of hydraulic elevators through the two cases below:

• As the elevator ascends: The pump pushes hydraulic fluid through the pipes into the cylinder. The pressure building up in the cylinder generates a thrust force that pushes the piston, thereby propelling the entire cabin vertically upwards. When the cabin reaches the selected floor, the system stops the pump and closes the valve to keep the cabin stationary in the correct position.

• When the elevator is descending: At this time, the control system will open the solenoid valve, allowing the oil in the cylinder to flow back to the reservoir. With the thrust from the piston gone, the cabin will slowly descend and stop precisely at the desired floor thanks to the valve closing at the right moment. In case of overspeeding, the safety valve will automatically lock, preventing the cabin from continuing to move and minimizing risk to users.

Advantages and Disadvantages of 200kg Hydraulic Elevators

200kg hydraulic elevators are becoming increasingly popular due to their compact design, making them suitable for family homes and buildings with limited space. Let's explore the outstanding advantages and disadvantages of this 200kg hydraulic elevator model:

Advantages of a 200kg Hydraulic Elevator

• Low investment cost : When installing a hydraulic elevator, you may not need to build a machine room or dig a pit. This significantly reduces installation costs compared to cable-driven elevators.

• Smooth and quiet operation: The 200kg hydraulic elevator operates smoothly and quietly thanks to its piston and hydraulic oil mechanism. With a noise level of only about 40-48 dB, equivalent to normal conversation, this ensures a peaceful environment for the whole family, avoiding discomfort during daily use.

• Energy saving: This type of elevator consumes only about 50% of the electricity compared to other conventional elevators, thanks to its operating mechanism which only consumes power in the upward direction.

• Automatic Rescue System (ARD): This system will automatically bring the cabin to the nearest floor for safe evacuation in the event of a power outage.

• Emergency stop button: Located inside the cabin, this button immediately stops the elevator's operation in emergency situations.

• Overload warning and landing door lock: Automatically detects when the weight limit is exceeded and a mechanical locking system ensures absolute safety at landing doors.

• Infrared sensors: These help detect obstacles at the elevator door, preventing hand or body entrapment during entry and exit.

• Door not fully closed safety feature: If the cabin door or landing door is not completely closed, the elevator will not operate to ensure user safety.

• Safety brake: The mechanical braking mechanism will automatically activate if the cabin exceeds its design speed, ensuring the cabin does not fall freely.

• Emergency valve: Allows the cabin to be lowered manually in case of an emergency.

Disadvantages of 200kg Hydraulic Elevators

• Limitations on the number of floors: 200kg hydraulic elevators are generally only suitable for houses and buildings with a maximum of 5 floors because the piston may malfunction if the number of floors is too high. Additionally, elevator journeys exceeding 5 floors will consume more electricity.

• Environmentally unfriendly: Because hydraulic elevators use oil to operate, oil leaks can occur during use, potentially damaging the ground or the floor. This can easily recur even after prompt repairs and negatively impact the elevator's lifespan.

• Noise from the pump: During operation, the pump and motor can produce noise. Therefore, avoid placing it near bedrooms or common living areas to ensure a quiet home.

• High maintenance and repair costs: Although the initial investment cost is cheaper than cable-driven elevators, most components are imported, so repairs will be limited and expensive.

Technical Specifications of the 200kg Hydraulic Elevator

200kg hydraulic elevators are typically installed in small or renovated homes. Therefore, to maximize space and natural light, it's advisable to use a steel or aluminum frame and glass walls for the elevator shaft. The technical specifications of a 200kg hydraulic elevator are shown in the table below:

Since a 200kg hydraulic elevator can only accommodate a maximum of two people at a time, many families of three are also interested in the 250kg hydraulic elevator model .

Price List for 200kg Hydraulic Elevators

The current price for a 200kg hydraulic elevator ranges from 275,000,000 to 900,000,000 VND . This price depends on factors such as the type of frame and shaft, the number of floors served, the cabin size, the elevator shaft, and the type of landing doors, etc. Below is a price list illustrating various types of 200kg hydraulic elevators for your reference to help you make an informed choice:
