Today, we will introduce and familiarize you with the common types of high-altitude work platforms. The high-altitude work platform originated in Europe and America, and is known as Aerial Work Platform or AWP in English. A high-altitude work platform is a specialized equipment used for high-altitude operations, mainly for high-altitude operations in the fields of construction, equipment maintenance, equipment installation, and building cleaning. In China, it can also be called high-altitude work platform, lift truck, elevator, lifting platform, etc. To be precise, the high-altitude work platform we usually refer to refers to high-altitude work equipment with a moving speed of less than 10km/h, which can be used for personnel to climb and work at heights, and has a carrying capacity of less than 500kg. Therefore, calling a high-altitude work platform a high-altitude work vehicle is actually an incorrect name. The movement speed of aerial work vehicles is relatively fast. According to national regulations, they need to be registered with professional departments and undergo special inspections by the local quality supervision bureau every year. Operators must hold a special equipment operation certificate.

Classification of high-altitude work platforms:

The lifting forms of high-altitude work platform arms can be divided into:

1. Personal mobile single type

2. Curved arm high-altitude work platform

3. Straight arm high-altitude work platform

4. Scissor type aerial work platform

5. Trailer type aerial work platform

6. Spider style aerial work platform

7. Mast type aerial work platform

The birth of high-altitude work platforms has greatly improved production efficiency, and most importantly, ensured the safety of high-altitude workers. Today's high-altitude work platforms are designed to be more user-friendly, precise, high-tech, and mobile while ensuring safety. High altitude work platforms can be divided into personal single mast sleeve (or column) high-altitude work platforms, double mast column high-altitude work platforms, scissor type high-altitude work platforms, curved arm high-altitude work platforms, and straight arm high-altitude work platforms based on the form of the boom.

The world's first scissor lift aerial work platform was launched by UpRight Inc in 1972, the world's first straight arm aerial work platform was launched by JLG in 1970, and the world's first curved arm aerial work platform was launched by Genie in 1985. Therefore, the three American brands UpRight, JLG, and Genie have become the three major brands of aerial work platforms in the world. With the development of the economy. Many European brands have emerged, such as Haulote from France, Nifty from the UK, MANTIOU from France, ATN from France, SKYJACK from Canada, BASKET from Italy, IMER from Italy, AIRO from Italy, HAB from Germany, PB from Germany, Kletzler from Germany, and other foreign brands. At the same time, high-altitude work platforms in China are constantly developing, giving birth to many domestic brands.

With the development of global architecture and the rise of high-rise buildings, the maintenance and cleaning of indoor buildings have become difficult. Spider style aerial work platforms, originally designed for high-altitude operations such as building maintenance, have emerged. FACLON, a Danish company, launched the earliest spider style aerial work platform in the 1970s, followed by the birth of German TUPEN, Italian Palazzani, Italian EASYLIFT, Italian BASKET, and Italian CMC spider style aerial work platform brands. The characteristics and working principle of high-altitude work platforms are a type of lifting equipment composed of a walking mechanism, hydraulic mechanism, electric control mechanism, and support mechanism. Hydraulic oil is pressurized by a vane pump and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve, causing the piston of the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure is adjusted through an overflow valve. The reading value on the pressure gauge is observed.

The principle of high-altitude work platform products is divided into curved arm high-altitude work platforms, scissor type high-altitude work platforms, mast type high-altitude work platforms, and straight arm high-altitude work platforms according to their working methods. The aerial work platform is a replacement product of the folding arm lift (lifting platform) and the scissor lift (lifting platform). It can be widely used for decoration and renovation of stations, docks, airports, hotels, postal and telecommunications, municipal gardens, grain depots, cleaning companies, public building facades, or installation and maintenance of power systems, etc. This elevator has the advantages of light weight, self-propelled operation, electric starting, self-supporting legs, simple operation, large working surface, especially the ability to cross obstacles for high-altitude operations.

1. High altitude work platforms can be divided into four wheeled mobile, two wheeled towed, car modified, electric scooter, assisted self-propelled, and lifting heights ranging from 4 meters to 18 meters. This series of products has a load capacity ranging from 0.1 to 0.8 tons, and can also be customized according to user requirements, with a maximum load capacity of 10 tons.

2. High altitude work platforms are widely used for factory maintenance in industrial and mining enterprises, municipal construction, and decoration in hotels and guesthouses, with reliable quality and complete performance.

3. Users can choose the power mode and configuration according to their own usage scope:

① The power system includes: battery DC power supply, single-phase or three-phase power supply, and diesel engine.

② Walking: assisted self-propelled, two wheel traction, self driving, and car modified.

③ Support legs: mechanical support legs, hydraulic support legs, ordinary hand cranked support legs, and pull-out support legs.

④ Control system: explosion-proof electrical control system, remote control system, PIC control system.

⑤ Hydraulic pump station: domestic lifting platform dedicated pump station, Italian imported pump station

⑥ External protective devices: organ cover type, mesh type, iron plate sealed type.

The high-altitude work platform is widely used in various industrial enterprises and production lines such as automobiles, containers, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different working heights. At the same time, it can be equipped with various table forms (such as ball bearings, rollers, turntables, rotation, tilting, expansion and contraction), and combined with various control methods (separation, linkage, explosion-proof). It has the characteristics of smooth and accurate lifting, frequent starting, and large load capacity, effectively solving various lifting difficulties in industrial enterprises, making production operations easy and smooth. The high-altitude work platform mainly achieves the function of lifting and lowering through the pressure transmission of hydraulic oil. Its scissor mechanical structure provides high stability for the lifting of the elevator. The wide work platform and high load-bearing capacity make the high-altitude work range larger and suitable for multiple people to work at the same time. It makes high-altitude operations more efficient and safer.
