The Complete Guide to Elevator Knowledge: From Principles to Safety, Read This One

I. The Basic Structure of an Elevator: Eight Systems Working in Harmony

A modern elevator is a complex mechatronic product composed of mechanical and electrical parts-1. Functionally, an elevator consists of the following eight major systems-25:

1. Traction System — The "heart" of the elevator. Its function is to output power, converting electrical energy into mechanical energy to drive the car. It mainly consists of the motor, brake, gearbox, traction sheave, wire ropes, and deflector sheaves-25. The working principle is "friction drive"—the motor drives the traction sheave to rotate, and the friction between the wire ropes and the traction sheave generates traction force, moving the car and counterweight (connected at opposite ends of the ropes) in opposite directions-23.

2. Guide System — The "track" of the elevator. Its function is to restrict the degrees of freedom of the car and counterweight, ensuring they move along the guide rails. It consists of guide rails, rail brackets, and guide shoes-25.

3. Car System — The passenger "cabin." Composed of the car frame and car body, this is the part that directly carries passengers-25.

4. Door System — The safety "gateway." Its function is to ensure safe passenger entry and exit, consisting of door frames, door panels, automatic door locks, car doors, and door operators-25.

5. Weight Balance System — The energy-saving "secret." Its function is to balance the weight difference between the car and the counterweight, with a balance coefficient typically of 40%–50%-25. It is precisely because of the counterweight that the motor requires only minimal power to drive the elevator.

6. Electric Drive System — The power "source." It provides power and controls the elevator's speed, consisting of the traction motor, power supply system, speed control devices, etc.-25.

7. Electrical Control System — The "brain" of the elevator. It controls and manages elevator operation, including control panels, floor indicators, control cabinets, etc.-25.

8. Safety Protection System — The "defense line" for life. It ensures safe elevator use, preventing and eliminating all safety hazards during operation-25.

II. Elevator Safety Protection: Three Lines of Defense for Every Ride

Many people have concerns about elevator safety, worrying about "elevator free-fall." SOLKER Elevator tells you that such concerns are unnecessary—modern elevators have at least three safety defense lines-38.

First Defense Line: Speed Limiter. A speed limiter is an overspeed detection device, typically installed in the machine room or at the top of the hoistway-. When the elevator overspeeds or loses control, it cuts off the safety circuit through an electrical switch, thereby cutting off the system power and forcing the elevator to stop immediately-38.

Second Defense Line: Safety Gear. If the car continues to fall at high speed after the speed limiter sends a stop signal, the safety gear is triggered—it firmly clamps the car onto the guide rails, bringing the elevator to an immediate stop-38. The speed limiter and safety gear work together as a linked protection device in case of overspeed or loss of control-.

Third Defense Line: Buffer. The buffer is installed on the floor of the pit at the bottom of the hoistway-. When the car lands on the buffer, it absorbs and dissipates all inertial and impact forces, keeping them within the range bearable by the human body-38.

In addition, elevators are equipped with a series of other safety measures: landing door locks and car door electrical interlock devices (ensuring the elevator cannot start when doors are not closed), photoelectric door safety protection devices, car overload alarms, power supply phase failure protection, and more-25. SOLKER Elevator tells you that a qualified home elevator must meet the most stringent safety standards—international certifications such as EN 81 and ASME A18.1 are basic requirements-12-19.

III. Home Elevator Drive Systems: Traction vs. Forced-Drive

For homeowners considering installing a home elevator, choosing the right drive system is a key decision. There are two mainstream drive systems for home elevators-23:

Traction Elevators are the classic choice with a century of proven technology-23. Key advantages include: quiet and smooth operation (permanent magnet synchronous gearless machines eliminate mechanical gear friction noise)-23, energy efficiency (using a counterweight to balance the car's weight, the motor requires only about 1kW of power, with monthly electricity costs typically not exceeding 20–30 RMB)-23, and long service life (the counterweight system ensures balanced forces, extending lifespan to more than double that of counterweight-less platforms)-23.

Forced-Drive Elevators (also known as positive-drive elevators) are suitable for space-constrained installations, requiring no counterweight and featuring a more compact structure-23.

SOLKER Elevator tells you that different homes and different building structures suit different drive systems. SOLKER offers a rich product lineup—the model-mini series (forced-drive elevator) and the model-S, model-Q, and model-A series (traction elevators)-23—to meet diverse needs ranging from compact spaces to spacious villas.
