Folding arm lift is a 360 ° rotating lift off people or goods of hydraulic lifting tool. Folding arm lift with mobile convenience, simple operation, a large work surface, a good balance of performance characteristics, in the case of uneven road surface, which can simultaneously support four legs, one leg support can also facilitate operational use, which are widely used in the station , docks, public buildings and other needs in high-altitude operations industries and fields. Chinese name: folding arm lift applies to: municipal, power, street type: hydraulic lift tool features: easy to move, easy to operate one-use folding arm aerial vehicles are widely used in municipal, electricity, street lighting, advertising, communications, photography, installation and maintenance of gardens and climbing operations, cross folding arm aerial vehicles [1] through, docks, airports, ports, large industrial and mining industries. For the wild variety of rugged terrain, a wide range of space operations, mainly used in construction, bridge construction, shipbuilding and construction, airports, mines, ports, telecommunications and power facilities and outdoor advertising engineering machinery and equipment. Diesel folding arm lift: no external power supply, erection suitable for field work at height, walking and diesel powered lift, big power, walking speed. Trailer folding arm lift: can be hung on the car, synchronized with the car, suitable for field-altitude operations. Lift: 1, 2 with 380-220V power supply, power supply is not convenient, you can use the battery-driven lift. Good looks, easy to walk. Car folding arm lift: the Boom Lift installed in the car, the use of power-driven car lift. Field far away for high altitude operations. 2 Features (1) new self-propelled hydraulic special chassis. Developed with independent intellectual property rights of self-propelled aerial work platform trucks, using a hydraulic integration, reliability, design and computer-aided design technology, successfully developed a full hydraulic drive, self-propelled special chassis, breaking the previous domestic aerial work platform lift trucks or cranes can only adopt restrictions on vehicle chassis modified design. (2) with load driving, good job stability. Chassis structure breaks the traditional design theory and methods, on the train platform by optimizing the overall layout and load distribution, reducing the center of gravity shifted. The unique wide-angle hinge point backwards type structure, a reasonable set of multiple counterweight module, effectively balance work torque. Using H-type variable cross cut of composite box beam frame and high load solid rubber tires, increasing the overall stiffness of the chassis, ensure the machine running, the stability of the job process, to achieve a high-altitude platform truck with load driving capabilities. (3) multi-function, multi-purpose operating system. Through the front bracket arm, lifting devices can be quickly installed or manned platform, material lifting, lifting and manned aerial work and other functions, as well as an extended job fast switching devices and various working device provides the interface . (4) a unique three-dimensional rotation lifts devices. Three-dimensional rotation lifts device designed to automatically keep both gesture by lifting materials, but can be adjusted to any height requirements for lifting material in the space, anywhere and in any direction, speed, precise control sensitive, fretting performance, meet the large cave on aerial work and ventilation pipe installation requirements. Three works by the vane pump hydraulic oil to form a certain pressure, the oil filter, explosion-proof solenoid valve, throttle valve, check valve, balance valve into the lower end of the cylinder, so that the hydraulic cylinder piston moves upward , heavy lifting, the upper end of the hydraulic cylinder return oil through flameproof solenoid valve to the tank, which is adjusted by the rated pressure relief valve, pressure gauge readings by observing the pressure gauge. Hydraulic cylinder piston downward movement (both heavy fall). Explosion-proof hydraulic oil through solenoid valve into the upper end of the hydraulic cylinder, hydraulic cylinder through the lower back to the oil balance valve, check valve, throttle, explosion-proof solenoid valve to the tank. In order to decrease the weight stable, safe and reliable braking, set the balancing valve, balancing loop back to the oil on the road, keep up the pressure, so that the rate of decline from the weight change, the throttle valve regulates the flow, speed control movements. In order to secure the brake to prevent accidents and increase check valve, namely hydraulic lock, ensure that when an unexpected burst hydraulic lines can safely self-locking. Installed voice alarm overload, overload or equipment failure to distinguish. 4 With the current development of the purchase method of social science and technology, more and more widespread use of aluminum lift, whether it is architecture, civil engineering, and people's daily lives are inseparable hydraulic lifting machinery, many businesses have to seize this opportunity to invest in building plant, along with rain after lifting machinery companies like bamboo shoots in the major industrial city of the provisional legislature, but the lifting machinery industry is still unusually hot, in short supply, it can be seen from the side, and now the rapid social development, promote the development of the industry and the people demand, however, as buyers lined How to choose a good company merchandise lifting machinery become an important topic. A: Optional lifting machinery, not blindly buy, to do adequate market research, as well as site visits to determine the size and extent of the company's credibility. This is first and foremost is a must, and now the market many small businesses to cut corners in order to reap the violence, so that the lifting of product quality is greatly reduced, although they will sell very cheap, but this time with the machinery is not long, but the risk factor great. Therefore, as the purchase price can not covet a little cheaper and lead to greater small regret. II: Comprehensive survey data you choose better cost lifting machinery, from the selection of its technical parameters as well as the practicality and versatility, usually aluminum lifting machinery, there are many, including the (car lift, fixed lifts, hydraulic lifting platform, scissor lift, etc.) for each of the technical parameters and has a slightly different purpose, but there are many features similar place, therefore, as a customer you want to buy with the purpose that you buy a mechanical lift what to do, and what kind of lifting machinery to meet your needs and use more. Three: Finally, after the arrival of equipment, unpacking inspection to check whether the random technical information is complete, random parts, tools, accessories are consistent with inventory, equipment and accessories for damage, defects, etc., and make unpacking acceptance record
