Eight major applications of eight major systems for elevators

The four major spaces of the elevator, the eight major systems, the four major space-based computer room parts of the eight application technologies, the well and pit, the car, and the landing.

Eight system traction system: The main function of the traction system is to output and transmit power to run the elevator. The traction system is mainly composed of a traction machine, a traction rope, a guide pulley, and a reverse pulley.

Guide system: The main function of the guidance system is to limit the freedom of movement of the car and the counterweight so that the car and the counterweight can only move up and down along the guide rails. The guide system consists of guides, guide shoes and guide rails.

Car: The car is an elevator component that carries passengers and goods and is the working part of the elevator. The car consists of a car frame and a car body.

Door System: The main function of the door system is to seal the entrance to the landing and the entrance to the car. The door system consists of car doors, landing doors, door openers and door locks.

Weight balance system: The main function of the system is to relatively balance the weight of the car. During the operation of the elevator, the weight difference between the car and the counterweight can be kept within the limit, so as to ensure that the traction drive of the elevator is normal. The system is mainly composed of counterweights and weight compensation devices.

Electric drive system: The function of the electric drive system is to provide power and implement elevator speed control. The electric drive system consists of a traction motor, a power supply system, a speed feedback device, and a motor speed controller.

Electrical Control System: The main function of the electrical control system is to exercise and control the operation of the elevator. The electrical control system is mainly composed of a control device, a position display device, a control panel (cabinet), a leveling device, a selector and the like.

Safety Protection System: Ensure the safe use of the elevator and prevent all accidents that endanger personal safety. Lift speed limiter, safety gear, rope clamp, buffer, safety touch panel, landing door lock, elevator safety window, lift overload limit device, limit switch device.

Eight major application technology 1, all-digital passenger identification technology (all passengers before entering the elevator to identify, including eyeball recognition, fingerprint identification)

2. Digital intelligent safety control technology (through passenger identification system or IC card and digital monitoring equipment, refusing to enter from outside)

3. The fourth-generation machine room-less elevator technology (the main engine must be separated from the guide rail and the car. There is no resonant resonance, and the speed can reach 2.0M/S or more. The maximum can be used in more than 30 floors.)

4. Two-way safety protection technology (two-way safety pliers, two-way speed limiter, which must be used in Europe, China is being widely used)

5, rapid installation technology (change the past elevator installation method, can quickly assemble)

6. Energy-saving technologies (using energy-saving technologies to make elevators more energy-efficient)

7, digital monitoring technology (completely using a computer for elevator monitoring and control)

8, wireless remote control and alarm device (when the elevator produces a fault, the elevator can send fault information to the mobile phone through the wireless device, and send a signal through the mobile phone for simple control of the elevator.)
