Passenger elevators are an integral part of modern life. As Elevator Construction Engineering, we use these technological wonders to enable you to cross the floors of buildings safely and comfortably. Thanks to our safety and innovative approach, every journey is enjoyable and safe.
Elevators are those in which the lifting work is carried out by means of an electrically driven pump that sends hydraulic fluid to a lifter that directly or indirectly affects the cabin. In these elevators, the downward movement is carried out by the weight of the cabin itself. In hydraulic elevators, the machine room is generally located at the first landing level. Here, there is an oil tank and on it, the hydraulic machine (mechanism), the control panel and the hoses through which the hydraulic fluid passes. Inside the elevator shaft; There is the cabin, the counterweight, if any, the cylinder piston system, the suspension mechanism and the buffers.
The pumped oil passes through the hydraulic machine by meeting certain conditions and moves the cylinder through pipes. The cylinder may be directly or indirectly connected to the cabin. The cabin pushed by the cylinder is moved to the required floor with the received control.
Hydraulic elevators are generally used in residences, villas and houses, buildings undergoing renovation, in cases where additional loads are not desired on the building statics (for example, renovation of old buildings), factories, and shopping malls as panoramic. Elevators must generally undergo necessary maintenance on a monthly, 6-monthly and annual basis, as per the contracts made.
Areas of Use
Commercial Buildings:
It is widely used in commercial buildings such as office buildings, shopping malls, hotels and restaurants.
Hospitals:
Hydraulic elevators used for patient transportation in hospitals provide comfort for patients and healthcare personnel.
Warehouse and Production Facilities:
It is widely used in warehouses and manufacturing facilities for material handling operations.
Disabled Access:
Hydraulic elevators are used to facilitate access to buildings for disabled individuals.
Hydraulic elevators stand out for their reliability, energy efficiency and wide range of uses. They provide a safe and effective way to overcome height differences and play an important role in many sectors.
Hydraulic Elevator Basic Elements and Features
Hydraulic elevators have a different working principle compared to other types of elevators. Here are the basic elements and features of hydraulic elevators:
Cylinder (Piston): The main component of a hydraulic elevator, the cylinder or piston is a rod that moves on the elevator car. A cylinder filled with hydraulic oil moves up or down when pressure is applied.
Hydraulic Pump: The hydraulic pump, which is the main power source of the hydraulic system, is a device that pumps hydraulic oil into the cylinder. It can be an electric or motor-driven pump.
Hydraulic Oil Tank: A reservoir where hydraulic oil is stored. This tank balances the oil level of the system and allows the oil to be reused when necessary.
Valves: In hydraulic elevators, valves control the flow of hydraulic oil. These valves are important to ensure the smooth operation of the elevator.
Electric Motor: Providing power for the hydraulic pump, the electric motor plays a critical role in operating the elevator.
Control Panel: The control panel is where the electrical components that control the operation of the elevator are located. This panel may contain buttons, indicators and security systems.
Cables and Ropes: In hydraulic elevators, steel cables or ropes are the components that guide and balance the movement of the cabin and the counterbalance weight.
Hydraulic elevators are preferred especially when the building height and carrying capacity are limited. They can be more cost effective due to their simpler design compared to other types of elevators. However, hydraulic elevators are more suitable for certain applications because they require a machine room and have a slower moving structure.
Advantages
Reliability: Hydraulic elevators have a long life thanks to the robustness of their hydraulic systems. These elevators are resistant to daily use and require little maintenance.
Overcoming Height Differences: Hydraulic elevators are used to overcome height differences inside or outside of buildings. This allows for the quick and safe transportation of people and materials.
Energy Efficiency: Hydraulic elevators offer an advantage in terms of energy efficiency. They can recover energy during lowering, which reduces operating costs.
Quiet and Comfortable: Hydraulic elevators operate quietly and provide a comfortable ride for passengers. This increases the user experience.
Disadvantages
Space Requirements: Hydraulic elevators may require a machine room, requiring more space in the building.
Slow Speed: They may operate slower than other types of elevators, so they may not be preferred in tall buildings or places that require fast transportation.
Risk of Oil Leakage: Hydraulic oil is used in hydraulic elevators and there is a risk of leakage of this oil, which can lead to environmental problems.
Cost: Hydraulic lifts can be more affordable than other types of lifts, but in some cases the installation cost can be high.
These advantages and disadvantages should be taken into consideration when deciding whether hydraulic lifts are preferred depending on specific applications and requirements.
