The simple way is to tie two ladders, wrap them firmly on the top, and add 1.2 meters of rope below to connect them to form a simple triangular support. The ladder should be about 4.5 meters high.
I recommend using the safe approach: using an electric lifting platform. The electric lift has small size, light weight, easy to move, stable lifting, small swing, large load capacity, large platform area, excellent stability, flexible operation and convenient implementation. Its light appearance allows it to exert the highest lifting capacity in a very small space. In the case of power failure, the product is equipped with an emergency descending device, a safety device to prevent the elevator from overloading, a leakage protection device and a phase loss protection device, and a safety explosion-proof device to prevent the rupture of the hydraulic pipeline.
Electric lifting platforms are widely used in factories, hotels, buildings, shopping malls, stations, airports, stadiums, etc. It can be used for maintenance of equipment, painting decoration, replacement of lamps and lanterns, electrical appliances, cleaning and maintenance, installation and maintenance of power lines, lighting appliances, elevated pipelines, etc., high-altitude cleaning, etc. One-man work at height. It can easily enter and exit the general door opening corridor, and can enter the general elevator to send into the multi-storey operation; the two-phase power supply is used as the power, and the speed change is stepless, so that the user's aerial work is safer, more convenient, and the noise is smaller. Easy and quick to use, it is an ideal climbing equipment.
Lifting platforms used in life
The invention of the lifting platform for skyscrapers made skyscrapers possible, and passenger transport is also a common use of lifts*. The passenger capacity required for a passenger lift depends on the size of the building and its use. The carrying capacity of typical passenger lifts ranges from hundreds of kilograms to more than 2,000 kilograms. Lifts used in buildings below four storeys may be hydraulic. Lifts with less than 10 storeys generally use a speed of 1.5 m/s (300 ft/min). Speeds of 2.5 m/s (500 ft/min) and 6 m/s (1200 ft/min) can be achieved above 10 floors.
Most high-rise office buildings are equipped with passenger lift platforms. In order to increase the speed, efficiency and usable area of the lift, most high-rise buildings will divide the elevator into an array, each group is responsible for a part of the floor, and make different adjustments and schedules according to the usage patterns of different times and different floors. There are also some very tall skyscrapers, and passengers need to use the non-stop fast lifts to go from the ground to the sky lobby on the upper floors, and then transfer to the lifts between different floors to reach their destinations. A small number of high-rise buildings are equipped with the latest type of lifts, and the elevator pre-call system can be used to pre-call the designated floor to be reached on the office floor or lobby.
I have traveled in the "cabs" of the passenger lifting platforms of some luxury clubs, and the inside is beautifully decorated, some with marble or even gold. Some of the passenger lifts are air-conditioned and have televisions for passengers to watch. Some passenger lifts have transparent cars that are placed next to the exterior walls of buildings for sightseeing by passengers.
Freight lifting platform is a kind of freight lifting machinery that must be manually controlled by the lift door, freight lifts are generally larger than passenger lifts and have more loads, ranging from 2000 to 5000 kg, most of them are traction type. There is generally no good decoration in the freight elevator to avoid damage when transporting goods, and there are generally special elevator control personnel on duty to control the elevator door switch.
Rack and pinion lifts (commonly known as "cages" in Hong Kong) are sometimes used in construction sites, warehouses and other places to transport goods and allow workers to ride. This type of lifting platform does not have a lift shaft and uses a rack rail to support and move the car.
There is a very small freight lifting platform, called dumb waiter in English, which is specially used for transporting food, cups and plates in multi-storey restaurants. These miscellaneous lifts are also used to transport books in multi-storey libraries.
There are also in supermarkets, parking lots and so on. In short, lifts are very popular in life, which is convenient for you, me and his production and life.
