Definition
Elevator should be defined as: a platform or a semi-enclosed platform lifting machinery or device that carries people or goods up and down the vertical passageway. It is a whole consisting of platforms and the equipment, motors, cables and other auxiliary equipment used to manipulate them.
A Brief History of the Development of Lifts
The earliest appearance of similar elevators can be traced back to ancient China and European countries. At that time, tools such as potter's wheels were used to transport people and goods vertically. The modern elevator is a product of the invention of the steam engine in the nineteenth century. In 1845, the first hydraulic elevator was born, and the liquid used at that time was water. In 1853, the American Elisha Otis [Elisha Otis] invented the automatic safety device, which greatly improved the safety of the steel cable traction elevator. On March 23, 1857, a five-story store in New York, USA installed the first passenger elevator using Otis safety devices. Since then, the use of lifts has been widely accepted and developed at a high speed. The original lifts were propelled by steam engines, so the buildings they housed had to be fitted with boiler rooms. In 1880, the German Siemens invented the elevator using electricity, and since then the veritable "elevator" has officially appeared. Since then, the use of lifts has been widely accepted and developed at a high speed.
In modern times, what we use to lift goods is a kind of wooden ladder, which is very inconvenient to use and dangerous to climb. The first city in China to install lifts is Shanghai. In 1907, two Otis lifts were installed in the six-storey Huizhong Hotel. The first commercial elevator in Taiwan was installed in 1932 during the Japanese occupation period. It was located in the "Juyuan Department Store" in Taipei City, and it was called Liulong at that time. At present, the elevators produced in China have different product models, and the lifting heights range from 4 meters, 6 meters, 18 meters or even hundreds of meters. Use domestic and foreign advanced hydraulic, motor, pumping station systems, hydraulic system explosion-proof devices and hydraulic self-locking devices. It has the irreplaceable advantages of other products such as novel design, reasonable structure, balanced lifting, simple operation, and convenient maintenance. Widely used in plant maintenance, industrial installation, equipment maintenance property management, warehouse, aviation, airport, port, station, machinery, chemical industry, medicine, electronics, electric power and other high-altitude equipment installation and maintenance.
Now, the development of elevators is at a peak state. Since most manufacturers or individuals choose multi-storey buildings in order to improve the utilization rate of the site, a device is also needed to facilitate the lifting and lowering of goods. Due to the high cost and low carrying capacity of ordinary elevators, it is not suitable for loading goods of tens or hundreds of tons, so hydraulic lifts with high carrying capacity have been developed by cargo lift supplier to assist production and cargo transportation. The hydraulic lift is safe and has a large load capacity, and it is easy to maintain, which makes this special industry develop faster.
The Classification of Lifts
(1) According to the different structure of the lift:
Scissor lifts, cylinder lifts, aluminum alloy (column) lifts, articulating arm lifts (renewal of folding arms), guide rail chain lifts (elevators, freight elevators), steel cable hydraulic lifting devices.
1. Scissor lift
(1) Classification: Hydraulic scissor lift for sale are divided into mobile scissor lift platform and fixed scissor lifts; the mobile scissor lift platform are divided into traction and self-propelled scissor lift.

Different power forms can be selected according to different requirements (such as: three-phase AC power supply, single-phase AC power supply, DC power supply and internal combustion power, etc.), equipped with a manual hydraulic device, it can work as usual in a power failure or no power supply place, and can be extended and retracted The platform can be extended to the required position when the platform length is insufficient, thereby improving work efficiency. It is an ideal equipment product for modern tall buildings and equipment, and a must for safe and civilized production at high altitudes.
(4) Uses: Suitable for large-scale high-altitude continuous operations in airport terminals, aircraft repairs, stations, docks, shopping malls, stadiums, residential properties, factories and mine workshops, etc. Some products have the function of automatic walking, which can walk fast and slow under different working conditions. Only one person in the air can operate the machine to continuously complete up and down, forward, backward, turning and other actions. When the machine is at a standstill, the wheels are always in the braking state, and can reliably brake on a 6-degree slope. High-quality rubber wheels with large diameter and wide width enable users to effectively protect the ground and increase the friction of braking at the same time.
2. Cylinder lift
(1) Introduction: The cylinder-type elevator is a multi-stage hydraulic cylinder that rises upright. The hydraulic cylinder is made of high-strength materials and good mechanical properties. The tower-shaped ladder-shaped protective frame makes the lifting platform more stable. Even at an altitude of 20 meters, you can feel its superior smooth performance. It is mainly used for installation and maintenance of power lines, lighting appliances, overhead pipelines, etc., and high-altitude operations such as high-altitude cleaning.

3. Purpose
Articulated boom aerial work platforms can be divided into two types: straight arm and curved arm according to the arm extension mode. They are mostly used in places with high height requirements such as shipyards. This type of machine is safe and easy to move, but the cost is high. Widely used in factories, automatic warehouses, parking lots, municipalities, stations, airports, theaters, exhibition halls, docks, construction, decoration, logistics, electricity, transportation, petroleum, chemical industry, hotels, gymnasiums, industrial and mining, enterprises, etc. repair. It is the best choice for maintenance of machinery, paint decoration, replacement of lamps, electrical appliances, cleaning and maintenance, etc. It can be designed and manufactured according to individual needs. This type of lift is commonly used by fire brigades.
According to the different ways of movement, it can be divided into
1. Mobile lift
The newly designed new generation of products adopts new alloy profiles. Due to the high strength of the material, the deflection and swing of the lifting platform are extremely small. Its light appearance can exert the highest lifting capacity in a very small space. Makes it easy for one person to work at heights and is mobile for work.
2. Fixed lift
The fixed lift is a kind of lift with good lifting stability. It cannot be moved and can only be fixed for work, making it easy to work at heights. It is mainly used for the transportation of goods between production lines or between floors; materials on-line and off-line; adjustment of workpiece height during workpiece assembly; high-level feeder feeding; component lifting during large-scale equipment assembly; large-scale machine tool loading and unloading; storage loading and unloading The site is matched with forklifts and other handling vehicles for fast loading and unloading of goods.
According to the requirements of use, the fixed elevator can be equipped with auxiliary devices for any combination. For example, the elevator car can be used in conjunction with the conveying equipment at the entrance and exit, so that the conveying process is fully automated, and the operator does not need to enter the elevator, thereby ensuring the personal safety of the operator. And it can realize the transportation of goods between multiple floors to improve production efficiency; electrical control mode; working platform form; power form, etc. The correct selection of various configurations can maximize the function of the elevator and achieve the best use effect. Optional configurations for fixed lifts include artificial hydraulic power, movable flaps that are convenient to overlap with surrounding facilities, rolling or motorized roller tables, safety touch strips to prevent feet from being rolled, organ-type safety shields, and manual or motorized rotary workbenches , Hydraulic overturning table, safety support bar to prevent the elevator from falling, stainless steel safety net, electric or hydraulic elevator walking power system, universal ball table.
