Background
An arc elevator is one type of elevator, which refers to a device that is capable of transporting people or objects in a vertical direction. It is typically composed of one or more motors, cables or hydraulic systems and associated control systems. Elevators are widely used in buildings, construction sites, warehouses, etc. for moving people and goods from one floor or location to another floor or location in a convenient and efficient manner. The arc elevator is used as a lifter, and people can be transported up and down by vertically running and stopping at different floors. Compared with the traditional linear elevator, the arc elevator is characterized in that the car door and the floor door adopt arc designs.
The arc elevator is an elevator form with unique design, and the car door and the floor door of the arc elevator are designed in an arc manner, so that the arc elevator is more attractive compared with the traditional linear elevator. The design is common in places such as high-grade shops, hotels and the like, and adds modern sense and fashion sense to the building. The linkage assembly between the arcuate elevator and the car door is typically comprised of a motor, guide rail, and linkage. When a passenger presses a door opening button on a floor door or reaches a target floor, after a signal is detected by a sensor, the motor drives a connecting rod and a guide rail, so that the car door and the floor door are simultaneously opened or closed. This ensures that passengers get in and out of the elevator safely.
