What is a Hydraulic Freight Elevator?
Elevator is a system that provides the most effective transportation of people or goods in vertical architecture. With the use of elevators, time and cost savings, especially energy, are also provided.
In general terms, freight elevators are products that are used effectively in lifting and carrying weights that are difficult to lift and carry with human power. Elevators are produced to have different mechanical properties according to the area in which they will be used. These features, which constitute the working principle of the elevator, greatly affect the usage process.
The main feature of the hydraulic freight elevator is that it has a working principle based on a hydraulic system. Lifting process is done in the safest and most effective way in the elevator with hydraulic system. It can be used easily in different work areas and is effective in continuing the work flow more rapidly and systematically.
Hydraulic Elevator Working Principle and Technical Features
- A hydraulic freight elevator is a type of elevator that sends the cabin to a lifting system with the help of a pump, together with the movement of the hydraulic fluid. It works with the coordinated and automatic actuation of the elements in the hydraulic system.
- During the descent, the cabin's own weight and the effect of gravity are used.
- The engine is usually located on the lowest starting floor. Next to the engine, there is the hydraulic system on the oil boiler, the hoses through which the hydraulic fluid passes, and the control panel.
- In a hydraulic elevator, the pump is electrically actuated and pushes the oil so that the pistons move the elevator platform.
- With the elevator installation, floor distances are adjusted so that the platform can stay on that floor safely, whichever floor the load is desired to be taken. Anti-fall lock system is used.
- Elements such as chain, cylinder and shaft are included in the production process in a quality that will ensure the safety of the system.
- The limit switch transforms the mechanical displacement movement into an electrical signal, providing height sensitivity.
Hydraulic Elevator Usage Areas
Hydraulic freight elevators are products that are preferred especially in the process of safely transporting weights up to 1500 kg. Thanks to its high security, it is effective in lowering and lifting loads with the lowest risk. The hydraulic freight elevator usage area can be defined as all sectors and business areas that require the safe transportation of heavy loads.
Price Advantages and Disadvantages of Hydraulic Lifts
Advantages:
A remarkable feature of hydraulic freight elevators is that they use engine power when going up and they have a mechanism that makes use of gravity during descent. With this working principle, it saves energy consumption.
Thanks to the sensor that provides a controlled descent during descent, the security system that is expected in the freight elevator is included in the hydraulic freight elevators.
With the overflow valve, the formation of high pressure that threatens the safety during the lifting of the hydraulic freight elevator is prevented.
It is effective in creating working environments in accordance with occupational health and safety laws.
The manual emergency valve is designed to be used in emergency situations. Earthquake, fire, etc. It is used in emergency situations and provides the opportunity to go down to the nearest floor.
Hose burst valve, which is also important for safety, is also found in hydraulic freight elevators. The hose burst valve functions to prevent the load from falling by cutting off the oil flow in case of a hose burst for any reason.
The maintenance and repair process is much easier and offers long-lasting safe use.
It also provides an advantage as the risk of failure is very low.
Disadvantages:
Compared to other freight elevators, it has the feature of being a more expensive freight elevator at the initial installation stage.
It moves slower than other freight elevator types.
