[Self Crank aerial vehicles] which uses a hydraulic integration, reliability, design and computer-aided design technology, is a fully hydraulic drive, self-propelled special chassis  breaking the previous high-altitude operations lifts only use domestic cars or restrict crane chassis modified design. 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. Job car uses a unique wide-angle hinge point backwards type structure, a reasonable set of multiple counterweight module, effectively balance work torque. Using H-type variable cross-section of the composite box beam frame and high load cut rubber tires, increasing the overall stiffness of the chassis, ensure the machine running, stability  work process to achieve a high-altitude operations lifts load driving capabilities. [Self Crank aerial vehicles] can be quickly installed by lifting devices or manned platform front-end bracket arm , achieve material lifting, lifting and manned aerial work and other functions at the same time as an extended working device  well kinds of work fast switching device provides the interface. Three-dimensional rotation Aerial 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 good performance, to meet the large cave on aerial work and ventilation pipe installation requirements. [Own] Crank aerial vehicles use diesel or battery-driven, flexible, self-crank type aerial vehicles are widely used in municipal, electricity, street lighting, roads, docks, advertising, gardens, residential property, factories and mines and other industries workshop The wide range of lifting operations.
