Interior decoration often encounter headache, if the ordinary ladder can not reach! How to solve it?
The simple way is to tie two ladders, which are tightly wound on the top and connected with 1.2m rope on the bottom to form a simple triangle support. The ladder should be about 4.5m high. In this case, how about safety? It's inconvenient to move alone.
I suggest a safe way: use electric lifting platform. The electric elevator has the advantages of small size, light weight, convenient movement, stable lifting, small swing, large load, large platform area, excellent stability, flexible operation and convenient implementation. Its lightweight appearance can give full play to the highest lifting capacity in a very small space. In case of power failure, the product is equipped with emergency lowering device, safety device to prevent overload of elevator, leakage protection device and phase loss protection device, and safety explosion-proof device to prevent rupture of hydraulic pipeline.
Electric lifting platform is widely used in factories, hotels, buildings, shopping malls, stations, airports, stadiums, etc. It can be used for maintenance of machines and tools, paint decoration, replacement of lamps and lanterns, electrical appliances, cleaning and maintenance, installation and maintenance of power lines, lighting appliances, overhead pipelines, and high-altitude cleaning. Working at height by single person. It can easily enter and exit the general doorway corridor, and enter the general elevator to send it to the multi-storey building for operation; it uses two-phase or three-phase power supply as power, stepless speed change, making the user's high-altitude operation safer, more convenient, and less noise. It is an ideal equipment for climbing operation.
The invention of the lifting platform of skyscrapers makes skyscrapers possible, and passenger transport is the most common use of elevators. The passenger capacity required by the passenger lift is related to the building area and purpose. The carrying capacity of the general passenger lift varies from hundreds of kilograms to more than 2000 kilograms. The elevators used in buildings below the fourth floor may be hydraulic. Lift speeds for buildings below ten floors are generally 1.5 m / S (300 ft / min). More than 10 floors can reach speeds of 2.5 m / S (500 ft / min) to 6 m / S (1200 ft / min).
Most high-rise office buildings are equipped with passenger lift platforms. In order to increase the speed and efficiency of the elevator and the usable area of the building, most high-rise buildings will divide the elevator into an array, each group is responsible for some floors, and make different adjustments and scheduling according to the use mode of different floors at different times. In some very high skyscrapers, passengers need to use the non-stop fast elevator. First, they go to the high-rise air lobby from the ground (that is, the high-rise elevator lobby, sky lobby), and then transfer to the elevator between different floors to the destination. A few high-rise buildings are equipped with the latest elevator, which can use the elevator pre calling system, and the designated floor can be pre called in the office floor or hall.
I used to ride in the "cab" of the passenger lift platform of some luxury clubs, which was decorated beautifully, some of which were decorated with marble or even gold. Some passenger elevators also have air-conditioning and TV sets for passengers to watch. Some passenger lift cars are transparent. They are placed beside the exterior wall of the building for objective light.
The freight lifting platform is a kind of special lifting machinery which must be controlled by hand. The freight lift is generally larger and more loaded than the passenger lift, ranging from 2000 to 5000 kg, most of which are traction type. Generally, there is no good decoration in the freight elevator to avoid damage when transporting goods. Generally, there are special elevator control personnel on duty and controlled elevator door switches.
There is a very small lifting platform for freight transportation, called Dumb Waiter in English, which is specially used for transporting food, cups and plates in multi-storey restaurants. Such lifts will also be used to transport books in multi-storey libraries.
In construction sites, warehouses and other places, sometimes the rack and pinion mesh elevator (commonly known as "cage" in Hongkong) is used to transport goods and let workers ride. This kind of lifting platform does not have a lifting shaft, and uses toothed rail to support and move the car.
There are supermarkets, parking lots, 4S stores and so on. In short, lift is very popular in our life, which is convenient for our production and life.
