The invention of fixed electric lifting platform of skyscrapers makes skyscrapers possible. Passenger transportation is also the most common use of elevators. Passenger lift capacity is related to building area and use. The carrying capacity of general passenger elevators varies from hundreds of kilograms to more than 2,000 kilograms. Lifts used in buildings below four floors may be hydraulic. The speed of elevators used in buildings below 10 stories is generally 1.5 m/s (300 feet/minute). Speed of more than 10 stories can reach 2.5 meters per second (500 feet per minute) to 6 meters per second (1200 feet per minute).

Most high-rise office buildings are equipped with passenger lifts. In order to increase the speed, efficiency and usable area of the elevator, most high-rise buildings will divide the elevator into arrays, each group is responsible for part of the floor, and according to different time and different floor usage patterns, make different adjustments and dispatches. There are also very tall skyscrapers where passengers need to use non-stop high lift trucks, first from the ground to the high-rise air lobby, and then transfer to different floor elevators to their destinations. A few high-rise buildings are equipped with the latest type of elevator, which can be used to pre-call the designated floor in the office floor or hall.

Stainless steel carriers are widely used in factories, hotels, buildings, shopping malls, stations, airports, stadiums and so on. It can be used for the installation and maintenance of maintenance equipment, paint decoration, lamp replacement, electrical appliances, cleaning and maintenance, power lines, lighting appliances, elevated pipelines, etc., and high-altitude cleaning, etc. High-altitude work done by a single person. It can conveniently enter and exit general doorways and corridors, and can enter general elevators into multi-storey buildings for operation. It uses two-phase power supply as power, continuously variable speed, so that users can work safely, more conveniently and noisily at high altitude. Easy to use, is the ideal climbing equipment.
