Screw elevator: Structure and advantages and disadvantages

Screw drive elevator is an elevator model manufactured to high-end brand standards with modern, advanced technology. The diversity of screw drive elevator designs offers many unique advantages. This elevator model operates based on the combination of an electric motor with a screw drive, belt, and gear system. 

Screw drive technology is used for the elevator motor, so the operation process is extremely safe and smooth. The elevator cabin moves smoothly according to the pre-set operating direction of the elevator thanks to the support of the gear system. 

What is a screw drive elevator?

The biggest highlight in the design of screw drive elevator models is that no machine room installation is required. The elevator pit is not too deep, thus always ensuring the aesthetic appeal of the elevator. Houses with moderate height and not too large an area will be very suitable for using this type of elevator. 

Structure of a home screw drive elevator

Screw drive elevators have a relatively simple structure compared to the Mitsubishi elevator. To ensure stable operation of the elevator motor, strong support from the electric motor system, belt, and screw drive system will be needed. 

• Electromechanical system: Is the main motor of the elevator, the brain that helps the elevator operate smoothly, determining the operation of the elevator. 
• Screw drive system: Consists of a worm wheel and a screw shaft. The screw drive system's structure will bring a special highlight to the elevator. When the electric motor acts on the elevator's bolt devices, it helps the cabin operate up and down smoothly according to user requirements. 
• Drive belt: Is a special structural part of the elevator, closely linked to the operation when the elevator's motor and screw drive operate. The drive belt creates a circular motion, helping the elevator operate continuously, durably, and safely. 
• Safety brake system: Is an indispensable part of a screw drive elevator. It has the function of protecting users' safety when using the elevator. The safety system used for elevators is a braking system, which helps stop the elevator in case of a sudden power outage.

Other parts such as: Ecosilent drive system, control panel, glass wall system, etc., also play an important and indispensable role in the operation of a screw drive home elevator. 

Home screw drive elevator dimensions

Screw drive elevator dimensions will vary depending on the elevator's load capacity. Basic specifications of the screw drive elevator that readers can refer to: 

• Speed: 9m/min
• Overhead height: ≥2400mm
• Pit depth: ≥100mm
• Maximum travel: 18.000mm
• Number of floors served: ≤4
• Shaft dimensions: ≥1.1 m2

Operating principle of the screw drive elevator

Screw drive elevators operate based on the principle of meshing. When the elevator screw drive system connects to the motor, it acts on the belt and screw drive, creating movement. Consequently, the elevator cabin is raised and lowered according to the direction of the motor, which has been set up by the gear system. The systems combine harmoniously and mesh, creating smooth, stable movement for users. 

Operating principle of the elevator series using screw drive technology

Thanks to its optimized structure and operating principle, screw drive technology elevators have minimized malfunctions when the elevator is in operation. In particular, the motor and operating functions of the elevator are environmentally friendly, saving 45% electricity, significantly superior to other elevator models on the market. 

Should a screw drive elevator be installed for home use?

Screw drive type elevator is a model elevator has many advantages such as compact size, easy installation, and good space optimization, making it very suitable for families with small spaces, houses under 6 floors. Renovation projects often have small elevator shaft locations, so using a home screw drive elevator is considered the most suitable choice. Some information about the advantages and disadvantages of screw drive elevators will be available below: 

Advantages of home screw drive elevators

Users have positive reviews and satisfaction when experiencing screw drive elevators. Some advantages below are the answers to readers' questions.
