Working principle of construction elevator

Construction elevator is a common name, and its standard name should be construction elevator, which belongs to a kind of lifting machinery and equipment.

The construction elevator adopts modular structure. Because it is used in the construction process, the elevator will move continuously with the construction project, so its structure must be easy to disassemble and assemble. For example, after this site is used, the elevator will be dismantled and transported to another site to reassemble the elevator accessories for further use.

So, what is the working principle of this construction elevator? The main load-bearing structure of the construction elevator is self-contained and has low dependence on the building. Forced driving is often used, and the driving device is installed on the hanging cage. Through the rack-and-pinion transmission system, the two cooperate with each other, thus realizing the lifting of the elevator. You may have seen gears and racks in mechanical clocks. The gears are round, and the racks are straight, and they mesh with each other to realize movement.

The working principle of common elevators in our residential and commercial buildings is different from that of construction elevators. Elevator parts are mostly fixed on the building, and the main load is borne by the building. Its up-and-down movement is realized by wire rope.

There is a car in the elevator and a counterweight on the other side. You should notice that when the elevator goes up, there is a heavy object on the other side. They are connected by wire rope. The wire rope is driven by the driving device in the elevator machine room, which makes the elevator car and counterweight move up and down on the guide rail in the hoistway.

The construction elevator has safety equipment such as overload prevention, fall prevention and limit device. For example, in the elevator, there is a device to detect the weight. Once the weight of the car exceeds the specified range, the elevator cannot be started. There are settings in the elevator that strictly limit its travel. After the cage reaches the top, there is a limit to prevent it from exceeding the travel range.

There are also many elevator safety measures commonly used in our life, such as weight, speed, position, state and other monitoring measures, which will require higher and more accurate.
