The crank arm type aerial work platform is a kind of aerial work platform. It is composed of a folding arm and a telescopic arm. It can use its own power to walk short distances between work sites or sites. Equipped with a crank arm, it can move operators, Tools, materials, etc. are lifted into the air through the work platform, which can be closer to obstacles for various installation, maintenance and other operations and complete multi-angle cleaning work.
Crank arm type aerial work platform component structure
The overall structure of the crank arm aerial work platform is composed of a special chassis, a working boom, a three-dimensional full-rotation mechanism, a flexible clamping device, a hydraulic system, an electrical system, and a safety device.
Dedicated chassis. It is composed of engine, frame, walking mechanism, steering mechanism, etc.
working equipment. The working device is composed of a turntable, a working boom, and a flexible flexible chain.
Three-dimensional full rotation mechanism. The installation location of the equipment or system is generally determined by two parameters: elevation and direction.
Flexible clamping device. Mainly composed of fixed arm, telescopic arm, clamping soft belt, rocker arm and clamping cylinder.
Electrical and hydraulic systems. The hydraulic system uses a variable plunger pump and a quantitative gear pump to supply oil, driven by the engine.
safety devices. Equipped with an electric emergency system for forcibly stopping various movements of the driving system and working devices in an emergency.
There is a detection device under the lifting device to prevent the lifting mechanism from colliding with the boom mechanism during misoperation and causing damage. Install an anti-tilt sensor on the chassis, when the inclination of the body>5. When the time, the sensor can emit intermittent alarm sound through the buzzer. The range limiting device can automatically detect the extension length and elevation angle of the boom, and limit the operating range within a safe range according to the preset data. When the maximum operating range is reached, the boom movement is automatically stopped.
Working principle of crank arm aerial work platform
The boom system of the crank arm type aerial work platform is mainly composed of a crank arm structure, a telescopic arm structure and a flying arm structure.
The two parallelogram mechanisms of the crank arm type aerial work platform are connected together by the lower hinge structure 7, and together with the connecting rod 5 and the luffing cylinder 8 form a crank arm structure. When the luffing cylinder 8 is extended, the connecting rod 4 makes an upward luffing motion relative to the articulated structure 7. At the same time, driven by the parallelogram mechanism, the connecting rod 3 synchronously luffs and the connecting rod 1 is pulled through the connecting rod 5. 1 and connecting rod 2 therefore move upward relative to the vertical plate 6 of the turntable. Conversely, when the luffing cylinder 8 is retracted, the connecting rod will move in the reverse direction, that is, the downward luffing movement.
Benefits of crank arm aerial work platform
The crank arm type aerial work platform has more excellent ductility and performance. It is suitable for all jobs. The crank arm cart has the multi-directional positioning function of upward, downward and spanning, and is suitable for working spaces that are difficult to access.
Precise positioning: The self-leveling platform can be rotated 90 degrees to both sides. On different models, the short arm can move vertically from 130 degrees to 139 degrees. On the rotating arm, the 1.22 meter short arm can move 180 degrees horizontally to expand the work. range. The proportional controller allows you to control the speed of each function and make smooth and precise adjustments in crowded areas.
Reliable electric drive system: The crank arm type aerial work platform is equipped with a DC electric drive system, which can be used in construction environments that require no noise and zero emissions.
Compared with the straight arm type, the crank arm type is more flexible, safer and more efficient, and can perform 360-degree continuous rotation without dead angles. Therefore, the crank arm type aerial work platform is useful in the high-altitude depth exploration operation of special-shaped buildings. Advantage.
Is the articulated aerial work platform special equipment?
Since the crank-type aerial work platform is a hoisting machine, according to the special definition of the special equipment safety law for hoisting machines (electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects, the load range is greater than or equal to 0.5 tons From the point of view of the lift truck), the load capacity of the crank arm aerial work platform is usually under 0.5 tons, so the crank arm aerial work platform is not a special equipment.
Boom type aerial work platform brand
There are domestic and foreign brands of crank arm aerial work platforms. Here are a few well-known brands:
Brand of domestic crank arm aerial work platform:
Dingli crank arm aerial work platform
Zhejiang Dingli is the leading manufacturer of aerial work platforms in China and the only listed company in the industry. Its articulated aerial work platforms are available in three types: generator, battery and spider, totaling 8 models. The maximum working height ranges from 15.6m-43m, and all 名媛直播 have passed CE certification.
Xingbang crank arm aerial work platform
The Xingbang crank arm aerial work platform is divided into two types: diesel drive and electric drive. There are 6 models. The maximum working height is from 16m-46m, and the crank arm aerial work platform of 15m-18m is replaced and upgraded to a floating cylinder. The cross-country performance of the machine walking; the crank arm aerial work platform above 18 meters is equipped with Cummins electronic control engine, which has better performance.
Imported electric crank arm aerial work platform:
Genie crank arm aerial work platforms are divided into self-propelled and trailer-type. Among them, self-propelled is divided into two types: diesel drive and electric drive. There are 20 types of Z series, and the maximum working height is from 11m-41m. The Z series articulated aerial work platform provides upward, downward and spanning multi-directional positioning functions as well as excellent extension functions. It is suitable for indoor and outdoor use, even for construction sites without power supply.
There are two models of trailer-mounted crank arm aerial work platforms. The maximum working height ranges from 12m-17m. It uses a DC/gasoline hybrid engine, which is suitable for high-performance applications where driving speed, lifting speed and rough ground tolerance are important.
