Aerial work platforms can be seen everywhere in life. It is a product serving mobile aerial work in various industries such as aerial work, equipment installation, and maintenance. This article mainly introduces the classification and working principle of the aerial work platform.
1. Classification of aerial work platforms
1. Scissor aerial work platform
Scissor aerial work platform is a versatile special equipment for aerial work. Its scissor-type mechanical structure makes the lifting platform have higher stability after lifting, a wide working platform and a higher carrying capacity, which makes the aerial working range wider and is suitable for multiple people working at the same time. It makes the aerial work more efficient and safer.
Features:
The lifting mechanism is made of high-strength manganese steel jumbo tube. Equipped with safety protection device to prevent overloading of lifting platform. There is a safety protection valve to prevent the hydraulic pipeline from rupturing. Equipped with emergency descent device in case of power failure. This product is suitable for mobile high-altitude operations such as installation and maintenance of high-altitude equipment in various industries. According to different requirements, you can choose different power forms (such as: three-phase AC power supply, single-phase AC power supply, DC power supply and internal combustion power, etc.), plus manual hydraulic device, can work in the power outage or no power supply place as usual, and can be expanded and contracted The platform can be extended to the desired position when the length of the platform is insufficient, thereby improving work efficiency. It is an ideal equipped product for modern tall buildings and equipment, and is necessary for safe and civilized production at high altitude.
2. Vehicle-mounted aerial work platform
The vehicle-mounted aerial work platform is modified from the supporting platform and the automobile. It takes the power of the car engine, realizes the use of DC DC independent power source, and realizes the rotation and lifting functions of the elevator. It is suitable for high-altitude operation 名媛直播 with a wide working surface and a large range. It has the characteristics of large operation range and long continuous operation time. It is especially suitable for field inspection and street lamp inspection.
The battery-mounted aerial work platform is a special equipment for aerial work modified from a lifting platform and a battery car. It uses the original DC power of the battery car, without the need for an external power supply, to achieve the lifting of the lifting platform and the movement of the whole machine. It is easy to move, has a wide operating flow range, the product has no pollution and no exhaust gas, and has a large operating range and strong fluidity. Especially suitable for cold storage, crowded areas (train station, bus station, airport), etc.
3. Crank arm aerial work platform:

According to the performance, it can be divided into:
1) Mobile aluminum alloy aerial working platform: a new design of a new generation of 名媛直播, using a new type of aluminum alloy profiles, due to the high strength of the profiles, the deflection and swing of the lifting table is extremely small. Its light appearance can exert the highest lifting capacity in a very small space. It makes it easy for a single person to work at heights, and can move to work.
2) Fixed aluminum alloy aerial work platform: a new design of a new generation of 名媛直播, using a new type of aluminum alloy profile, due to the high strength of the profile, the deflection and swing of the lifting table is extremely small. Its light appearance can exert the highest lifting capacity in a very small space. It makes single-person high-altitude operation a breeze, can not move only fixed operation.
3) Telescopic tabletop aluminum alloy aerial work platform: The telescopic tabletop lift is combined with four-wheel mobile or vehicle-mounted customization. The platform can be freely expanded and contracted when working at height, thereby increasing the working range! Can be customized according to the actual situation of the customer.
4) Folding aluminum alloy aerial work platform: a household folding elevator, which belongs to a kind of elevator, especially a household folding elevator. The beam is composed of two steel plates, and it is welded and connected by a number of inverted "U" shaped connection cards, forming a gap in the middle, and the front and rear ends are respectively placed in the track formed by the gap by the trolleys connected by the retractable motor and the electric hoist . Therefore, the defects of unreasonable structure and inconvenient use of the existing domestic elevators are overcome. The utility model has the advantages of reasonable structure, simple manufacture, low cost, convenient use, strong practicability, and can be used by one machine for multiple households or by a single household.
6. Cylinder aerial work platform:
The cylinder-type aerial work platform is a multi-stage hydraulic cylinder that rises upright. The high-strength material of the hydraulic cylinder and good mechanical performance. The tower-shaped ladder-shaped protective frame makes the lifting platform more stable. Even at a height of 20 meters, you can feel its superior smooth performance.
GTC-A single ladder anti-transformation: The most common and most practical, using the GTC-A hydraulic elevator, ascending operation may no longer be an annoyance. It is widely used in stations, docks, hotels, airports and various occasions that require ascending operations.
GTC-B double ladder anti-transformation: new design, double ladder anti-rotation structure, double speed descent system, maximum rise of 35 meters, stable, reliable, beautiful, easy to operate is the biggest feature of GTTY-B hydraulic elevator. Double ladder anti-rotation structure to ensure the safety and stability of the operation. In addition, considering the actual environment on site, the lifting cylinder can be dumped to ensure the maximum range of machine operation.?Applicable occasions: workshops, hotels, buildings, shopping malls, stations, airports, stadiums, etc.
Main uses: installation and maintenance of power lines, lighting appliances, overhead pipes, etc., high-altitude cleaning and other single-altitude operations.
Power options: AC 220V (standard configuration), AC 380V power supply, DC power supply, hand pump.
2. Working principle of aerial work platform
The hydraulic oil is formed with a certain pressure by the vane pump, and enters the lower end of the liquid cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the liquid cylinder moves upward to lift the weight. The return oil at the upper end of the liquid cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. Its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.
The piston of the liquid cylinder moves downward (both heavy objects fall). The hydraulic oil enters the upper end of the liquid cylinder through the explosion-proof electromagnetic directional valve, and the return oil at the lower end of the liquid cylinder returns to the oil tank through the balancing valve, hydraulic check valve, throttle valve, and explosion-proof electromagnetic directional valve. In order to make the weight fall smoothly, and the brake is safe and reliable, a balance valve is set on the return line to balance the circuit and maintain the pressure, so that the falling speed is not changed by the weight. The flow rate is adjusted by the throttle valve to control the lifting speed. In order to make the brake safe and reliable, and prevent accidents, a hydraulic control check valve, that is, a hydraulic lock, is added to ensure that the hydraulic pipeline can be safely locked when it unexpectedly bursts. Overload sound control alarm is installed to distinguish overload or equipment failure.
