Let’s look at 3 key aspects of the screw elevator structure.
Installing an elevator in a home or building doesn’t necessarily require maximum speed. Importantly, the size of the elevator, aesthetics, and safety for occupants are crucial. KALEA Lift’s vision is to enhance daily life, and we offer elevator solutions designed to make a positive difference in people’s lives through increased comfort and beautiful design. Screw elevators are known for their safety, aesthetics, ease of installation, and many other advantages. What makes the screw elevator structure so special? Read the article below to learn more.
1. What makes the screw elevator structure so special?
Screw elevators utilize screw technology. The screw elevator structure is a perfect blend of a motor system and a screw, bolt, and belt system that creates movement. The device moves up and down in the direction of the engine through a gear system, creating rhythm, consistency, and safety for users. A screw elevator consists of three main parts: the screw, bolts, and belt.
1. Special Safety Braking System Integrated into Screw Elevators This type of elevator is extremely safe. It has comprehensive emergency systems, such as communication and emergency signaling systems, in case of unforeseen events while using the elevator. Thanks to its special structure, screw elevators offer high performance and safety. You don’t have to worry about the elevator falling because the screw shaft can support several tons of weight, as tested in Sweden. It provides an exceptional user experience. This is why this type of elevator is popular and widely installed in homes and buildings up to 6 stories high today.

2. Structure and Operating Principle of Home Screw Elevators
Home elevators with screw technology operate on the principle of circular motion. This allows the engine to work while the elevator moves up and down smoothly. The elevator is driven by a screw through the rotation of a nut on the screw shaft. Due to its unique driving principle and design, screw elevators are ideal for homes as they do not require an elevator shaft, pit, or machine room. Screw technology is a leading advanced passenger elevator technology today, integrating numerous outstanding safety features for a comfortable and confident travel experience.
Safety-focused, driven by a screw system. Certified by European Machinery Directive 2006/42/EC according to European manufacturing standards, ensuring system stability and achieving global certifications. Most importantly, the screw elevator standard we have obtained is EN 81-41 and undergoes further inspection SIL-3 a final manual for safety integrity checks in all critical components. Therefore, all KALEA Lifts, originating from Sweden, have the highest safety standards, receiving various European certifications before production.

3. What are the benefits of the screw home elevator structure?
It can be seen that the home elevator market is currently booming with a wide variety of types, sizes, manufacturing processes, materials, and designs. Choosing the right type of elevator requires homeowners to understand the advantages and limitations between different types of elevators for different home structures. Due to its unique operating principles, home elevators using screw technology have many outstanding advantages and are popular with customers today. These advantages include:
Screw-type home elevators come with safety features.: Screw elevators are designed to be non-removable, guaranteeing the strong and stable threads of the screw for smooth and reliable operation, avoiding problems.
Suitable for various areas: Screw elevators are designed to require only 1 square meter of installation space, making them suitable for many projects, especially those with limited space. They save space, eliminating the need for a machine room; tractor equipment and electrical cabinets are integrated into the pit. This allows the elevator to operate at full efficiency without consuming space for a machine room. Ideal for low-rise buildings.
High Aesthetics: This enhances the aesthetic value of the construction and reflects the owner’s status.
Installation and Maintenance Mode: Screw elevators have a shallow pit or require no excavation, no pit construction, and no machine room, making installation very easy and quick. Elevator maintenance cycles vary by brand. However, screw elevators generally require relatively infrequent maintenance, typically only 1-2 times per year. Safety, aesthetics, and minimal installation space are key advantages of screw elevators.
